2006 Mazda MX-5 Miata Sport — Sunlight Silver

What sets this one apart

Sport Suspension Package

The 2006 Miata Sport came with the coveted Suspension Package — a rare factory combo that most NC Miatas didn't get. Bilstein monotube shocks paired with stiffer springs and a limited-slip differential transform it into a genuine driver's car straight from Hiroshima.

Shock absorbers Bilstein Monotube
Front suspension Double Wishbone
Rear suspension Multilink
Spring setup Sportier rate vs. base
Differential Clutch-type (plate) LSD
Final drive ratio 4.10 : 1
Brakes — front 11.4" Ventilated Discs
Brakes — rear 11.0" Solid Discs
Steering EHPAS Rack & Pinion
Turns lock-to-lock 2.7 turns
Tires P205/45R-17
Wheels 17 × 7J Alloy

Bilstein Monotube Technology

Unlike twin-tube shocks, Bilstein's monotube design uses a single chamber with a floating piston separating oil from high-pressure gas. This prevents aeration (aka "fade") during hard cornering, giving this Miata consistent, predictable damping whether autocrossing or carving a backroad.

Clutch-Type LSD

The limited-slip differential is the secret weapon. When one rear wheel starts to slip, the LSD transfers torque to the wheel with more grip. The factory NC unit is a plate (clutch-type) LSD, not the Torsen design used in the NA/NB — a meaningful spec change for this generation. On the 6-speed Sport, this is only available on manual transmission cars — making it exclusive to drivers who row their own gears.

Manual-trans only option in 2006

Engineering Highlights

When Mazda introduced the NC for 2006, it wasn't a refresh — it was a ground-up rethink. These are the specific engineering decisions Mazda's own launch materials highlighted.

🏎 Nürburgring-Tested

Mazda's launch testing reportedly had the redesigned NC lapping the 13-mile, 73-turn Nürburgring Nordschleife roughly 15 seconds faster than the outgoing NB it replaced — a meaningful real-world validation of the new chassis, not just a marketing number.

⚖️ "Gram-by-Gram" Weight Strategy

Despite growing in every dimension, the NC added only about 27 lbs over the outgoing NB thanks to a deliberate component-by-component weight discipline. Aluminum was used for the engine block, hood, trunk lid, rear brake calipers, and front suspension control arms.

🔩 47% Stiffer Body Structure

Extensive use of high-tension steel increased torsional rigidity by 47% and flex stiffness by 22% over the previous generation. A stiffer chassis directly improves how precisely the car responds to steering, braking, and power input.

📍 Front-Midship Engine Layout

The engine was moved 5.3 inches further back compared to the outgoing generation, sitting almost entirely behind the front axle line. Combined with relocating the fuel tank and battery closer to the car's centerline, this lowers rotational inertia (yaw) for quicker, more predictable direction changes.

⚙️ Aluminum Power Plant Frame (PPF)

A rigid aluminum backbone structurally unites the engine, transmission, and differential into a single assembly. This largely eliminates drivetrain twist and lag, helping power reach the rear wheels the instant the throttle is applied.

🪡 Z-Fold Soft Top

The redesigned soft top uses a spring-assisted frame and single locking latch, allowing it to be raised or lowered from the driver's seat in seconds with one hand — and folds flush enough that no separate tonneau cover is needed.

🪑 Interior Redesigned Around Driver Biomechanics

Mazda used biosensor studies of driver movement to refine the shape of the gearshift knob, the position of the foot pedals, and the steering wheel's tilt range — aiming for the seating position to accommodate roughly 95% of male drivers without compromise.

🛞 Double-Wishbone Front / Multilink Rear

A fully independent suspension uses aluminum double-wishbone geometry up front and a multilink setup at the rear, both paired with gas-filled shocks — the foundation the optional Bilstein/LSD Suspension Package builds on rather than replaces.

The full package

What You've Got

🏁

2.0L MZR Engine

The 2.0L DOHC 16-valve four-cylinder with Variable Valve Timing (VVT) makes 170 hp — a meaningful jump over the 1.8L NB. The short-throw 6-speed makes the most of every gear.

🌬️

Soft Top Convertible

The classic manual folding soft top takes seconds to drop. Wind-in-the-hair is the whole point of the Miata, and the 2006 does it better than ever with improved NVH sealing over the NB.

🪑

Sport Interior

Urethane-wrapped steering wheel, body-hugging sport seats, and a tight, driver-focused cockpit. The Sport kept things simple — no leather, no Bose — just the essentials done right. Every control falls perfectly to hand.

🔴

4-Wheel Disc Brakes + ABS

Diagonal hydraulic dual-circuit ABS with 11.4" vented front rotors provide serious stopping power. The Sport package's firmer suspension means better weight transfer and brake feel.

💡

EHPAS Steering

Electro-Hydraulic Power Assist Steering gives you genuine road feel — it's not the numb electric assist of most cars. The 2.7 turns lock-to-lock ratio makes it wonderfully direct.

🛞

17-inch Alloy Wheels

The Sport trim stepped up to 17×7J aluminum alloys wrapped in P205/45R-17 rubber — larger than the base model's 16s, with a sportier sidewall profile to match the Bilstein tuning.

Miata Facts

Best-Selling Sports Car Ever The Mazda MX-5 Miata holds the Guinness World Record for best-selling two-seat sports car. Over 1 million sold globally by 2016 — and still going.

The NC Was Bigger The 2006 NC generation was the first Miata big enough to comfortably fit taller drivers. It grew 2.3 inches in wheelbase over the NB, making it more usable without sacrificing the fun.

Jinba Ittai Mazda's design philosophy means "horse and rider as one." This Miata was engineered so the driver doesn't just drive it — they wear it. The seating position, wheel angle, and controls all reinforce this.

Miata is Always the Answer Since the early 2000s, the phrase "Miata is Always the Answer" has been the unofficial creed of the sports car internet — a tongue-in-cheek truth about how versatile and capable the little roadster really is.

Silver is the Rarest Flex Sunlight Silver Mica is one of 8 exterior colors offered on the 2006 NC. Silver Miatas photograph incredibly — that complex metallic mica shifts from platinum to slate depending on the light.

52/48 Balance Near-perfect front-to-rear weight distribution. Most sports cars don't achieve this. Combined with the LSD and Bilstein shocks, this is the reason the Miata handles like it's on rails.

Global Production Milestones

The Miata holds the Guinness World Record for best-selling two-seat sports car — and Mazda has tracked every major production milestone along the way. Here's the timeline, straight from Mazda's own announcements.

531,890

May 2000 — First Guinness Record

600,000

January 2002

700,000

April 2005 — Just Before NC Launch

800,000

January 2007 — Early NC Era

900,000

February 2011

1,000,000

April 2016 — The Millionth MX-5

1,200,000+

As of 2025 — 35th Anniversary Year

📍 Where 2006 Sits in the Timeline

A 2006 Miata was built right at a major inflection point: the NC generation launched in August 2005, and Mazda crossed 700,000 cumulative units that same April — meaning every 2006 model year car was among the very first NC-era cars built after that milestone. By the time the NC's facelift arrived in 2009, total production had already passed 800,000.

Why This Matters

These aren't rough estimates — they're official Guinness World Records milestones, announced by Mazda at the time each threshold was crossed. The pace tells its own story too: it took the Miata about 11 years to go from zero to its first Guinness record (531,890 units), but under a year to add each subsequent 100,000-unit milestone during the NC and early ND years. The platform didn't slow down — it accelerated.

2006 NC1 Palette

Exterior Colors

Eight colors were available for the 2006 NC1. Several were exclusive to the launch year — never offered again on the NC.

Sunlight Silver Metallic

Code: 22V · ★ This build

Available 2001–2008. One of the most popular NC colors. Shows body lines beautifully in direct light.

Brilliant Black

Code: A3F · 2006–2014

The longest-running NC color. High maintenance but striking. Shows swirls easily — clay bar is your friend.

True Red

Code: A4A · 2006–2015

The only red available the entire NC run. Classic, vivid, unmistakably Miata. Ran all the way through the NC3.

Copper Red Mica

Code: 32V · 2006–2013

A deeper, more complex red-brown that shifts color in different light. Underrated — looks stunning in sunlight.

Winning Blue Metallic

Code: 27B · 2006 only ⚠️

A 2006-exclusive color. Never came back. Deep navy-to-blue metallic. NC1-only cars in this color are increasingly rare.

Nordic Green Mica

Code: 27C · 2006 only ⚠️

Another 2006-exclusive. A dark forest green mica that was replaced by Highland Green in 2007. Extremely rare today.

Marble White

Code: A5M · 2006–2009

Clean, classic white. Not a bright white — more of a warm off-white. Discontinued after 2009, replaced by Crystal White Pearl.

Galaxy Gray Mica

Code: 32S · 2006–2008

A darker, cooler gray than Sunlight Silver. NC1/NC2 only. Replaced by Liquid Silver in 2009 for the facelift.

⚠️ = 2006 NC1 exclusive — never offered on NC2 or NC3 · Velocity Red Mica (27A) was also available on the 3rd Gen Limited special edition only

Bolt Pattern

⚠️ NC Uses a Different Bolt Pattern Than Other Miatas

The NC switched to a 5×114.3 bolt pattern — shared with the contemporary Mazda6 and RX-8 — and is incompatible with NA, NB, and ND wheels, which all use 4×100. Wheels do not interchange across NC and other Miata generations.

Common Upgrades

225/45R17 on a 17×8 ET45 wheel — the most widely reported "safe" daily upgrade, about a 3% diameter increase over stock with no fender modification needed
Conservative offset range for wider stance without rolling fenders: ET40–ET48 depending on width
Keep total diameter change within ±3% of stock to preserve speedometer accuracy and OEM suspension geometry
Always verify the exact spec against the door jamb sticker — it's the definitive source, not a generic chart

Keep it healthy

Maintenance Intervals

🛢 Engine Oil

Every 5,000–7,500 miles with full synthetic. Track use: every 3,000 miles regardless.

Spec: 5W-30 full synthetic (Mazda factory spec)
Capacity: 4.5 qts with filter
Drain plug torque: 23–30 ft-lbs (new crush washer each time)
Filter: accessible easiest through front left wheel well

5W-20 is listed in some sources but 5W-30 is the NC spec

⚙️ Transmission Fluid

Every 30,000–45,000 miles. Many NC owners report dramatically smoother shifting after a fresh fill — especially important on the 6-speed.

Spec: 75W-90 GL-4 gear oil
Capacity (6-speed): ~2.2 qts
Recommended: Motorcraft XT-M5-QS, Redline MTL, Motul Gear 300
⚠️ GL-5 oils can harm brass synchros — stick to GL-4
Remove fill plug before drain plug — don't get stranded with an empty trans and a frozen fill plug

Fresh gear oil is the cheapest handling upgrade on an NC

🔴 LSD Differential Fluid

Every 30,000 miles — and this is the one most NC Sport owners neglect. The factory NC differential is a clutch-type (plate) LSD, which depends on clean, correctly-spec'd fluid with the right friction modifier to operate quietly and predictably.

Spec: 75W-90 GL-5 (differential requires GL-5, unlike the trans)
Capacity: ~1.0 qt
Recommended: Redline 75W-90, Motul Gear 300, Royal Purple Max-Gear
⚠️ Do NOT use standard GL-4 here — the diff needs GL-5
⚠️ Clutch-type LSDs typically need a friction modifier additive — check if your chosen gear oil already includes one
Symptoms of neglected LSD fluid: clunking under load, chatter in tight turns

GL-4 for the trans. GL-5 for the diff. Don't mix them up.

🌡 Coolant

First change at 120,000 miles or 10 years, then every 60,000 miles or 5 years after that. The FL-22 long-life formula is designed to last far longer than conventional coolant — don't flush it unnecessarily.

Spec: Mazda FL-22 long-life coolant (look for "FL-22" on radiator cap)
⚠️ Non-FL22 coolant can cause serious damage — don't use generic green antifreeze
Mix 50/50 with distilled water
Also: inspect NC power steering rack for fluid weeping past 80k miles

FL-22 only — it's on the radiator cap

🛑 Brake Fluid

Every 2 years or 24,000 miles. More frequently if the car sees track use — brake fluid absorbs moisture and its boiling point drops with age and heat cycles.

Spec: DOT 3 or DOT 4
Track/spirited use: upgrade to DOT 4 high-performance (Motul RBF 600, ATE Type 200)
Bleed all four corners; start at the corner farthest from the master cylinder
NC uses a dual-circuit hydraulic system — inspect reservoir level seasonally

Old brake fluid boils on track — flush it every 2 years minimum

⛓ Timing Chain — No Belt!

The NC's 2.0L MZR uses a timing chain, not a belt. This is one of the NC's biggest advantages over the NA and NB — no scheduled replacement needed under normal conditions.

✅ No timing belt replacement interval — ever
Chain is designed to last the life of the engine with proper oil changes
Listen for rattling at cold start — a sign of chain tensioner wear at very high mileage
NA and NB used a timing belt (interference engine) — a snapped belt = bent valves
⚠️ The NC's MZR is actually an interference design — the chain's reliability is what protects the engine, not a forgiving piston/valve clearance

One of the best reasons to own an NC over an NA/NB

⚡ Spark Plugs

Every 60,000 miles with iridium plugs (factory fitment).

Spec: iridium plugs — NGK ILKAR7L11 or OEM equivalent
Gap: 0.044 in (1.1 mm)
Modified or boosted cars: go one heat range colder
Don't use standard copper plugs at 60k intervals — iridium only for that interval

60k miles on iridium plugs is fine — don't over-service them

💨 Air Filter & Others

A few other items worth tracking:

Air filter: replace every 30,000 miles (clean at 7.5k and 22.5k intervals)
⚠️ NC has no cabin air filter — none of the NC models were equipped with one
Power steering fluid: inspect every 30,000 miles
Tire rotation: every 7,500 miles
Soft top: clean and condition vinyl every 3–4 months
Inspect rear window zipper and tension strap annually

The soft top is the most neglected NC maintenance item

Read the data plate

VIN & Build Sheet Reference

Every NC Miata's VIN follows the same 17-character format. Here's how to decode it — and what it can't tell you.

J M 1 N C 2 5 F X 6 0 X X X X X X

Positions 1–3: WMI

JM1 = Japan, manufactured by Mazda

Positions 4–5: Model

NC = Third generation MX-5 (2006–2015)

Position 6: Body Code

2 = Convertible soft top body style

Position 7: Restraint System

5 = Active belts with dual front and side airbags

Position 8: Engine

F = 2.0L MZR DOHC VVT (all NC trims, all years)

Position 9: Check Digit

X = Mathematically derived from all other VIN digits — used to verify the VIN is valid and unaltered

Position 10: Model Year

6 = 2006 model year

Position 11: Assembly Plant

0 = Hiroshima (Ujina Plant) — every NC Miata, every market, built at this single plant

Positions 12–17: Production Sequence

6-digit production sequence number unique to each vehicle — confirms exact build order within the model year

⚠️ What the VIN Does NOT Tell You

The VIN does not encode trim level (Sport vs. Touring vs. Grand Touring), exterior color, or whether a car has the Suspension Package. That information lives only on the build sheet / door jamb sticker and the original window sticker (Monroney). Two NC1s with identical VIN structures can be completely different cars underneath — always verify trim and options against the actual door sticker, not the VIN alone.

By the numbers

Is the Sport Actually Rare?

"Rare" gets thrown around loosely in car communities. Here's what's actually documented about NC1 production and option distribution.

2006 NC1 Trim Levels

Club Spec, base MX-5, Touring, Sport, and Grand Touring — plus the 3rd Generation Limited as a sixth, ultra-limited variant.

Trims Eligible for Suspension Pkg

Documented in period Mazda literature: the Suspension Package (Bilstein + LSD) was manual transmission only and explicitly not available on Club Spec, base MX-5, or Touring. Sport was the only trim where it was a true option — Grand Touring and Limited got it standard.

750

US-Bound 3rd Gen Limited

Out of 3,500 built worldwide for the NC1's launch, only 750 3rd Generation Limited Editions were brought to the United States — by far the rarest documented 2006 variant.

2006-Exclusive Colors

Winning Blue Metallic and Nordic Green Mica were both dropped after the 2006 model year — never offered again on any later NC.

What This Actually Means

A 2006 Sport with the Suspension Package isn't a numbered limited edition, and Mazda never published exact production splits by trim and option combination for the NC1. What's verifiable is narrower than that: the Suspension Package was deliberately restricted to a small subset of available configurations — manual-only Sport, Grand Touring, and Limited — by Mazda's own published option literature. That makes a manual Sport with the package a genuinely uncommon combination relative to the far more common Touring and automatic cars that made up the bulk of NC1 sales, even without an exact production number to cite.

What it cost new

2006 Trim Pricing

Original MSRP for every 2006 configuration, manual and automatic. Club Spec, Base, and 3rd Gen Limited were manual-only; Touring, Sport, and Grand Touring each offered an automatic for a $1,100 upcharge. Prices exclude tax, title, license, and the $560 destination charge.

Trim	Transmission	MSRP	Notable Standard Equipment
Club Spec	5-spd manual	$20,435	16" wheels, no A/C, stripped-down weekend-racer spec — manual only, no automatic offered
Base (MX-5)	5-spd manual	$21,435	A/C added, urethane wheel — manual only, no automatic offered
Touring	5-spd manual	$22,435	Fog lights, cruise control
Touring	6-spd automatic	$23,535	Same as manual — automatic models rated at 166 hp instead of 170
Sport (this build)	6-spd manual	$22,935	17" alloys, Bilstein + LSD Suspension Package optional (manual only)
Sport	6-spd automatic	$24,035	Suspension Package not available — automatic Sport rated at 166 hp
Grand Touring	6-spd manual	$24,435	Leather, Bose audio, Suspension Package standard
Grand Touring	6-spd automatic	$25,535	Suspension Package retained — automatic GT rated at 166 hp
3rd Gen Limited	6-spd manual	$26,700	Chrome accents, special wheels, manual only — 750 of 3,500 worldwide came to the US
MSRP figures per Edmunds/TrueDelta 2006 pricing data. Automatic upcharge was a flat $1,100 across all eligible trims. Destination charge was $560 for the 2006 model year ($1,040 to Alaska on some trims). Add roughly $500 for the Suspension Package on Sport where optioned.

The field in 2006

Competitor Context

When the NC launched in 2006, it entered a briefly crowded roadster segment. Here's how it stacked up — and why it's the only one still in production.

Honda S2000

2000–2009 · AP1/AP2

The S2000 was the enthusiast's choice: a 2.2L VTEC revving to an 8,200 rpm redline, 237 hp, and razor-sharp handling. More expensive (~$34k vs ~$22k for the Miata), harder to drive at the limit, and notoriously unforgiving below the VTEC crossover point.

✅ More power (237 hp vs 170 hp)
✅ Higher revving, more exotic feel
❌ ~$11k more expensive at base
❌ Peaky power band — frustrating in traffic
❌ Stiffer, less forgiving at the limit
❌ Discontinued 2009 — no parts pipeline

Verdict: a racecar for the road. Miata is the better daily driver.

Pontiac Solstice / Saturn Sky

2006–2010 · Kappa Platform

GM's answer to the Miata launched the same year as the NC and looked stunning — especially the Sky. But beneath the sheet metal were unresolved dynamics, a trunk that shrinks dramatically with the top down, and a complicated convertible top that required stepping out of the car to operate.

✅ Striking looks — especially the Sky
✅ 260 hp GXP/Redline turbo arrived for 2007 (base 2006 made 177 hp)
❌ Cramped interior, complex top operation
❌ Trunk space collapses to ~2 cu ft with the top down
❌ Less refined handling than the Miata
❌ Killed by GM bankruptcy in 2009

Verdict: beautiful but flawed. GM's collapse sealed its fate.

BMW Z4 (E85)

2003–2008 · 3.0i / 3.0si (2006 lineup)

The Z4 was the premium option — more GT than sports car, offering 3.0L inline-six power, a longer wheelbase, and much more interior refinement. Starting around $39k vs the Miata's $23k, it served a different customer entirely.

✅ More refined, better long-distance cruiser
✅ Inline-six sound and power
❌ ~$16k+ more expensive
❌ Much heavier — less agile
❌ Higher maintenance and repair costs

Verdict: a different class of car. Apples to oranges.

Nissan 350Z Roadster

2003–2009 · Z33

The 350Z Roadster packed a 3.5L V6 with 300 hp in 2006, making it more muscle car than sports car. Heavier, wider, and more powerful — but not more fun, and nowhere near as communicative as the Miata.

✅ Significantly more horsepower
✅ V6 sounds great at high revs
❌ Over 1,000 lbs heavier than the Miata
❌ Much less steering feel and feedback
❌ Higher running costs

Verdict: fast in a straight line. The Miata wins everything else.

Why the Miata Outlasted All of Them

Reliability

The MZR 2.0L is one of the most over-engineered, underworked engines in sports car history. High-mileage examples regularly exceed 200k miles with nothing but oil changes. The S2000's VTEC and the Kappa's turbo couldn't say the same.

The Right Weight

At ~2,500 lbs, the NC was heavier than the NA/NB but still lighter than every competitor on this list except the S2000. Weight is the enemy of fun — Mazda never forgot that.

Balance & Feedback

52/48 weight distribution, EHPAS steering with genuine road feel, and a chassis tuned for rotation and balance — not straight-line speed. The NC communicates more in one corner than the 350Z does in a full lap.

Value Over Time

The Solstice and Sky are forgotten. The S2000 is a cult car with climbing prices and dwindling parts. The 350Z Roadster rusts. The NC Miata — especially a Sport with Suspension Package — is now genuinely appreciating.

The economics

What It Actually Costs to Own

Everything above is about the car. This is about the wallet — insurance, parts, and where the value is actually heading.

🛡 Insurance

Older NC model years insure noticeably cheaper than newer ones. Industry rate comparisons put a 2010 NC around $900–1,000/year for full coverage with a typical driver profile — well below what a current-year Miata costs to insure, and far below most sports cars in general.

Among sports cars broadly, the Miata consistently ranks as one of the most affordable to insure
Lower horsepower and a strong safety record both work in its favor with insurers
Actual rates vary heavily by location, driver age, and driving record — get a real quote, this is a ballpark only

One of the cheapest sports cars in America to insure, full stop

🔧 Parts & Repair Costs

A 5-year total ownership cost study put a new Miata at roughly $42,000 all-in (depreciation, insurance, fuel, interest, maintenance) versus roughly $68,000 for a comparable BMW Z4 over the same period. NC parts specifically benefit from huge production volume and a massive secondary market.

Shared 2.0L MZR architecture across multiple Mazda models keeps parts plentiful and inexpensive
Strong used/salvage parts ecosystem — body panels, interior trim, and electronics are easy to source
Independent mechanics are comfortable working on Miatas — no dealer-only specialty service required

Among the cheapest sports cars in the world to actually own

📈 Resale & Appreciation Trend

This is the most interesting number on this page: Hagerty's market data shows 2006 model-year NC Miatas have appreciated as much as 51% since 2020 — while 2015 (final-year NC) examples are down 20% over that same span. Early NC1 cars are pulling away from the rest of the generation.

NC values broadly: typically $7,000–$16,000 depending on year, mileage, and condition
Younger buyers are driving increased interest in the NC specifically — it's transitioning from "used car" to "future classic" in real time
Clean, low-mileage Sport and Grand Touring trims with the Suspension Package command a premium over base/Touring
Manual transmission cars consistently outsell and out-value automatics in the resale market

2006 specifically is the NC's strongest-appreciating model year

⚖️ vs. the S2000, Dollar for Dollar

The clearest illustration of Miata value: market data has shown an average 2006 Miata priced around $9,000, while a comparable 2006 Honda S2000 averages roughly $23,000 — a gap of well over $14,000 for the same model year.

That price difference could fund serious suspension, brake, and exhaust upgrades on the Miata side
The S2000's smaller production numbers and cult following keep its prices elevated
For pure dollar-per-smile, the NC remains hard to beat

Same era, same idea, less than half the price

The Bottom Line

A 2006 Miata Sport sits in a genuinely rare spot for a 20-year-old car: it's cheap to insure, cheap to fix, and — unusually for something this old — may be worth more next year than it is today. Most cars this age are pure depreciation. This one might not be.

Speak the language

Glossary

This page uses a lot of Miata-specific shorthand. Here's what it all means, in one place.

LSD

Limited-Slip Differential. Splits power between the rear wheels intelligently — when one wheel starts to lose grip, it sends more power to the one that still has traction, instead of just spinning the loose one uselessly.

Clutch-Type (Plate) LSD

The type of LSD used in the NC Miata's factory differential. Uses a stack of friction plates, pressed together under load, to limit how much one wheel can outspin the other. Different from the gear-driven Torsen LSD used in the earlier NA/NB Miatas.

PRHT

Power Retractable Hard Top. A folding metal roof that opens and closes automatically at the push of a button — first offered on the NC starting in 2006, an alternative to the standard manual soft top.

EHPAS

Electro-Hydraulic Power Assist Steering. A steering system that uses an electric pump (instead of one belt-driven off the engine) to provide hydraulic assist — saves a small amount of power while still delivering genuine road feel.

VVT

Variable Valve Timing. Lets the engine adjust when its intake valves open and close depending on RPM and load — improves both low-end torque and high-RPM power compared to a fixed-timing engine.

MZR

Mazda's engine family name for the NC's 2.0L inline-four. Shared (in different displacements) across several Mazda models of the era — known for being simple, durable, and easy to maintain.

DOHC

Dual Overhead Camshaft. The engine has two camshafts per cylinder bank — one for intake valves, one for exhaust — allowing more precise valve control than a single-cam design.

Monotube Shock

A shock absorber design with a single oil-filled tube (rather than two nested tubes). Dissipates heat faster and resists fade better under hard, repeated use — the design Bilstein uses on the Sport Suspension Package.

Jinba Ittai

Japanese for "horse and rider as one." Mazda's core design philosophy for the Miata — the idea that car and driver should feel like a single, connected unit, with every input feeling direct and immediate.

NA / NB / NC / ND

Mazda's internal chassis codes for the four Miata generations, in order: NA (1989–1997), NB (1999–2005), NC (2006–2015), ND (2016–present). Enthusiasts use these codes more often than model years.

Curb Weight

The weight of the car as it sits ready to drive — full fluids, full fuel tank, no passengers or cargo. The standard number used to compare how heavy or light different cars are.

Wheelbase

The distance between the centers of the front and rear wheels. A longer wheelbase generally means a more stable, planted ride; a shorter one usually means quicker, more agile handling.
