Miata Wide Body Kits for the NC Miata!

The NC Miata (2006–2015) is often seen as the underrated middle child in the Miata lineup, but that doesn’t mean it has to stay stock and sleepy. Whether you're aiming to build a slammed show car, a head-turning weekend cruiser, or a functional track machine, a wide body kit can seriously level up your NC’s style and stance. In this guide, we’re diving deep into the best wide body kits and fender flares for the NC Miata, breaking down the pros and cons so you can find the perfect fit for your build.

What Is a Wide Body Kit, and Why Consider One for the NC?

So, what exactly is a wide body kit? In simple terms, it’s a set of exterior parts, usually including overfenders, side skirts, a front lip or bumper, and sometimes a rear diffuser, that extend your car’s body lines outward. This gives your Miata a beefier, more aggressive look. On top of the aesthetic upgrade, a wide body kit also gives you more room to run wider wheels and tires, which can mean better grip and handling (if you’re the type to push limits on track days).

But let’s be real: most people go wide body for the looks. A well-designed kit adds serious curb appeal, turns heads at car meets, and makes your NC look like it’s ready to eat up apexes, even if it’s just parked at the grocery store. The key is to choose a kit that fits your build goals, budget, and how much cutting you’re willing to do.

 1. CarbonMiata Wide Overfenders Kit

The CarbonMiata kit is arguably one of the most popular widebody options for the NC Miata, and for good reason. This 8-piece overfender kit is available in fiberglass, carbon fiber, or carbon-kevlar, giving you some flexibility in weight and finish. It adds around 35mm of width in the front and 45mm in the rear, which means you can run some seriously meaty wheels (think 9–10J with a low offset).

It’s designed primarily for NC2 and NC3 models, though NC1 owners can make it work with some trimming. The overall shape of the kit flows really well with the OEM lines, so it doesn’t look like an afterthought. That said, you’ll have to cut your OEM fenders and drill into the body, definitely not for the faint of heart. But if you’re committed to going full send, the CarbonMiata overfenders deliver big-time in terms of style and function.

2. Firefly-Speedshop Full Body Kit

If you want to go beyond just fender flares and create a fully transformed NC, the Firefly-Speedshop full body kit might be your jam. This one’s a comprehensive aero kit with front and rear bumpers, side skirts, and an optional ducktail spoiler that screams retro racecar. Made from fiberglass (FRP), it fits all NC generations, though you’ll want to specify whether you’re rocking a hardtop or soft top.

The biggest selling point here is how cohesive everything looks once installed. It’s not a mix-and-match setup, it’s a fully realized design from bumper to bumper. Of course, coming out of the UK, it’s not the cheapest option once you factor in shipping and possible import duties. Also, Firefly has a bit of a reputation for slow customer service, so use PayPal or a protected payment method just to be safe. Still, if you’re building a showstopper, this kit is hard to beat.

3. Mazdaspeed Front Bumper Replica by CarbonMiata

Looking for something that steps up your style without going full widebody? The Mazdaspeed front bumper replica is a clean OEM+ option for NC1 Miatas (2006–2008). It mimics the original factory Mazdaspeed bumper, giving your car a slightly more aggressive and refined front end without looking too wild.

Made from either FRP or carbon fiber, this bumper mounts to the OEM points, which means install is fairly straightforward. Just note that it only fits NC1 models without extra mods. It’s a great choice if you want to keep your build subtle but still stand out from the crowd.

4. Couture M Speed Front Bumper (Duraflex USA)

This one’s for the tuner fans. The Couture M Speed front bumper from Duraflex brings big energy to the front end of your NC1. It features large openings for airflow, perfect if you're planning to run a front-mount intercooler or just want a more dramatic look.

Made from Duraflex’s flexible FRP material, this bumper does require some body shop love, expect to spend time sanding, prepping, and fine-tuning the fitment. It sits low, too, so make sure your driveway isn’t too steep. Still, if you want a front end that makes your Miata look like it escaped from a Tokyo drift scene, this is a solid option.

5. TopMiata Fender Flares (Bolt-on)

On a budget or just not ready to cut into your car’s metal? The TopMiata bolt-on fender flares offer a great compromise. These 4-piece flares are made from ABS plastic or fiberglass and give your NC a wider look without the commitment of full overfenders.

They bolt on (though some trimming and alignment are needed), and they work well with stock or mildly lowered setups. Just don’t expect a ton of extra wheel clearance, they’re more for style than serious width gains. But for under $600, they’re an easy way to give your Miata a wider, meaner stance.

6. OEM Front Bumper (Mazda Factory)

Not everyone is chasing wild aero. If you’re restoring a stock NC or just want a clean, factory-fresh front end, the OEM Mazda bumper is still available from sources like YoshiParts. It fits perfectly (as you’d expect), and the quality is top-notch.

That said, it’s not an upgrade, it’s a replacement. You won’t turn heads at cars and coffee, but if you love your NC for its original charm, this is a reliable option.

Quick Comparison Table

Paint or Wrap?

Wrapping is perfect if you want flexibility. You can protect the fiberglass or carbon parts, test out wild colors, and peel it off later if you change your mind. But if you’re aiming for a flawless, color-matched finish that lasts, paint is the way to go. Just make sure the parts are properly prepped, fiberglass especially needs careful sanding and priming.

Installation Tips

Before you grab the drill or the rivet gun, test fit everything. Seriously, don’t skip this. Fiberglass parts often need a bit of love to line up perfectly. If your kit requires cutting your OEM panels (like the CarbonMiata overfenders), make sure to apply rust protection after the cut. For hardware, consider using rivnuts or M5/M6 bolts instead of rivets, makes maintenance way easier down the line. And if bodywork isn’t your thing, hiring a good shop can save you headaches and time.
