The Mazda MX-5 Miata is one of the easiest cars to personalize, and a body kit is usually the first visible change after wheels and suspension. The catch is that "Miata body kit" covers four very different generations, and almost nothing interchanges between them. This guide breaks down which parts fit which Miata, what each piece actually does, and how to choose materials. You can browse everything in one place in our Mazda Miata MX-5 body kits and aero collection.
Which Miata do you have? NA, NB, NC and ND explained
Body panels are generation-specific, so start by confirming your chassis code:
- NA (1989-1997): the original pop-up headlight Miata. Lightweight, simple bodywork and a huge aftermarket for lips, flares and ducktails.
- NB (1998-2005): fixed headlights and a reshaped nose and tail. NA bumpers and skirts do not bolt on.
- NC (2006-2015): a larger car on a different platform. Parts are often split by early (2006-2008) and facelift (2009-2015) bumpers.
- ND (2016-present): the current, smallest-footprint modern Miata. Roadster and RF (retractable fastback) share many front and side parts, but check rear parts carefully.
Always match the year range in the product title to your car before ordering.
Miata front lips and splitters
A front lip sits under the bumper, lowers the visual nose and can reduce the amount of air going under the car. It is the most popular first aero part because it changes the look a lot for little cost. On a lowered Miata, ground clearance matters: driveway angles and parking blocks are the main thing to think about before going deep.
For NA owners building a wide-body look, the NA Roadster wide-body front lip and under diffuser (fiberglass) is designed to pair with wider fenders. If you are unsure whether you want a lip or a full splitter, our front lip vs splitter guide explains the difference.
Miata side skirts
Side skirts fill the gap between the front and rear wheels, making the car look lower and visually tying the front lip to the rear diffuser. On the Miata there are two common styles: full replacement rocker covers and thinner add-on extensions (rocker splitters) that bolt under the factory rocker.
- ND: 2016-2023 ND side skirt extensions in real carbon fiber, glossy or matte.
- NB: 1998-2005 NB side skirt extensions in fiberglass.
- Any generation: universal 78.7 in (2 m) sectional side skirt extensions in ABS, which can be trimmed to length for NA, NB, NC or ND.
More detail on materials and mounting is in our side skirts guide.
Miata rear diffusers
A rear diffuser sits under the rear bumper and finishes the lower line of the car. On a street Miata it is mostly a styling piece; on a track car it works best as part of a complete package with a flat underside. Options on SLR include the ND rear bumper diffuser splitter (carbon fiber with fiberglass backing) and the NA Roadster rear under diffuser with fins in gloss carbon fiber. See what a rear diffuser does for the background.
Miata spoilers, ducktails and wings
The Miata's short trunk lid suits a small ducktail or lip spoiler, and track builds often step up to a wing. Ducktails add a clean, period-correct look; wings are for drivers who want visible rear downforce and do not mind the race-car look. NC owners can look at the 2009-2015 NC rear trunk spoiler wing in ABS (gloss black or carbon-look). Our ducktail vs wing guide covers the trade-offs.
Miata carbon and fiberglass hoods
A replacement hood is a popular ND upgrade for both looks and weight. Carbon fiber is the premium option; fiberglass (FRP) is cheaper and is usually painted to match. For the ND there is a 2016-2025 ND Roadster and RF carbon fiber hood and an ND fiberglass replacement hood. Read our carbon fiber hood guide for fitment and install tips, including hood pins and latch checks.
NA Miata fender flares and wide body
Wider wheels and aggressive offsets eventually need more room than the factory arches give. Bolt-on flares are the classic NA solution: the 1989-1997 NA fender flare kit (4 pieces, fiberglass, black) covers all four corners. Flares usually require cutting or rolling the factory fender lip, so plan wheel and tire sizes first. Our fender flares guide explains bolt-on flares vs wide fenders.
ABS vs fiberglass vs carbon fiber: which material?
- ABS plastic: flexible and forgiving on scrapes, often ready to install. Best for daily-driven lowered cars.
- Fiberglass (FRP): lightweight and affordable, but more brittle and normally needs prep and paint. Common for wide-body and race-style parts.
- Carbon fiber: the lightest and most premium look, best for hoods and visible trim. Costs more and needs UV-protected clear coat to stay glossy.
Install tips for a Miata body kit
- Test-fit every part before paint or drilling.
- Use the factory mounting points where they exist, and add support brackets for lips and splitters.
- Expect some trimming and adjustment on fiberglass parts; a body shop can blend gaps.
- Check ride height: low lips and skirts on a lowered car need care on steep ramps.
Miata body kit FAQ
Do NA and NB Miata body kits interchange?
No. The NB has different bumpers, headlights and rear styling, so NA bumpers, lips and diffusers do not bolt on. Some universal parts, like trim-to-fit side skirt extensions, work on both.
Will ND Miata Roadster parts fit the RF?
Front lips, side skirts and hoods are often shared between the ND Roadster and RF, but rear parts can differ. Check that the listing names RF before buying.
What is the best first body kit part for a Miata?
A front lip or side skirt extensions. They change the stance of the car the most for the money and install with basic tools.
Do I need to paint a Miata body kit?
Fiberglass parts usually need paint. ABS parts are often finished in black, and carbon fiber parts are normally left in their clear-coated finish.
Where can I find Miata body kits?
SLR carries front lips, side skirts, diffusers, spoilers, hoods and fender flares for every generation in the Miata body kits and aero collection.
