Enthusiasts love the Miata for its lightweight frame, retro pop-up headlights, and iconic roadster charm. However, a few exterior upgrades can modernize and personalize the car, giving it a fresher, more aggressive appearance. Beyond aesthetics, these modifications can enhance performance and aerodynamics, improving the overall driving experience. So, whether you’re aiming for a track-ready look or a sleek daily driver vibe, let’s explore some of the best exterior mods to elevate your NA Miata.

Body Kits

Body kits are among the most transformative upgrades you can make to your Miata. Adding a body kit redefines the car’s stance, making it look lower, sportier, and much more aggressive. But body kits aren’t just about looks; they can also improve aerodynamics by reducing drag, making the car feel more stable at higher speeds. For NA Miata owners, the CarbonMiata Body Kit is a popular option. This kit includes a front lip, side skirts, and a rear lip. Each of these components contributes to a cohesive, streamlined appearance that makes the Miata look more “planted” on the road.

The CarbonMiata kit is available in fiberglass and carbon fiber, both durable and lightweight options. Carbon fiber, however, has a unique woven pattern that adds a distinctive, high-end look. Installation can be relatively straightforward, although aftermarket kits sometimes require minor fitment adjustments. Tools like a drill, measuring tape, and perhaps a Dremel for precise adjustments will come in handy. Checking alignment and drilling points before fully securing each part can ensure a perfect fit. This body kit is the foundation of a bolder, more refined Miata aesthetic, setting the stage for other exterior mods.

Diffusers

A diffuser is an excellent addition to any Miata looking to sport a track-inspired look while also benefiting from a functional aerodynamic upgrade. Diffusers help reduce air turbulence under the car, which can improve stability and may even provide a slight increase in fuel efficiency. The R Theory Version 1 Diffuser is a solid option for the NA Miata, offering a refined yet sporty look without overwhelming the car’s profile.

This specific diffuser is smaller than some other options, making it a subtle choice that still adds plenty of style. Installation involves removing the rear bolts and attaching the diffuser with the included brackets. It’s helpful to use a jack stand to set the desired height and ensure sufficient ground clearance, especially if the Miata has been lowered or has an aftermarket exhaust. The R Theory diffuser, combined with other rear modifications like the ducktail trunk, gives the Miata a track-ready look that’s both stylish and functional.

Spoilers

Spoilers bring both aesthetic appeal and performance benefits to the Miata. They add a sporty, aggressive touch while generating downforce, which enhances road grip and stability, especially during spirited drives or track days. The CarbonMiata RS-Type GT Wing is a great spoiler option for NA Miata owners who want both form and function. Designed specifically for the Miata, this GT wing provides a sleek, track-inspired look and balances well with the car’s shape, ensuring it doesn’t overpower the Miata’s classic lines.

Constructed from carbon fiber, the GT Wing is lightweight, helping to maintain the car’s agile performance. The installation is straightforward, with a few tools and some patience required to get it perfectly aligned. Once installed, the GT wing provides additional stability by increasing downforce, especially noticeable when cornering or driving at higher speeds. This spoiler is a worthwhile addition for Miata owners looking to boost their car’s performance and style in one go.

Front Lip

Adding a front lip is one of the quickest ways to give the Miata a more aggressive front-end look. A front lip extends below the bumper, visually lowering the car’s stance. The classic eBay front lip is a popular, budget-friendly option that still delivers a substantial aesthetic upgrade. While lower-cost options like these may require a bit of improvisation for a perfect fit, the difference they make is well worth it.

Installing a front lip is straightforward, typically requiring bolts or screws to secure it to the bumper. Some adjustments may be needed to align the lip properly, as aftermarket lips are not always a perfect match. The result? A front end that looks sportier and more aggressive, bringing the whole look of the car together.

Lighting Upgrades

Upgrading the NA Miata’s headlights to LEDs can bring a more modern look while offering practical benefits like improved visibility and lower energy consumption. LED headlights are brighter and last longer than halogen bulbs, making them a smart investment for both style and safety. For Miata owners who want to keep the pop-up headlights but enjoy LED benefits, pop-up to LED conversion kits are available and easy to install, providing a fresh look with an iconic twist.

LED upgrades not only look great but also provide much better lighting for night driving. These upgrades enhance visibility on darker roads, helping keep you and your Miata safe.

Wheels and Tires

Wheels are a powerful visual statement, and they can also greatly influence performance. Rota RB wheels are a popular choice among Miata owners due to their classic design that complements the Miata’s vintage aesthetic. The Rota RBs are also lightweight, which improves handling, braking, and acceleration by reducing rotational mass.

Pairing lightweight wheels with high-performance tires can dramatically improve grip and handling, making the Miata even more fun to drive. Performance tires help get the most out of the wheels’ benefits, so it’s worth investing in a quality set to maximize your Miata’s potential.

Exhaust Systems

Upgrading the exhaust is a classic move for Miata enthusiasts, and the RoadsterSport 3 exhaust is a great option for those wanting an aggressive yet refined sound. This exhaust adds a deep, sporty tone without being overly loud, making it perfect for both daily driving and spirited weekend drives.

Performance-wise, the RoadsterSport 3 reduces backpressure, which can lead to a slight increase in horsepower and better throttle response. Installation is straightforward, and the RoadsterSport 3 fits the Miata’s design while giving it an exhaust note worthy of a performance car.

Additional Styling Enhancements

For those wanting extra flair, there are a few smaller mods to consider. An offset license plate bracket relocates the license plate for a clean, JDM-inspired look on the front end. Delrin door bushes can reduce door flex, giving the car a more solid feel when closing the doors. If you’re tall, removing the stock sun visors and adding blanking plugs can also give better visibility and a tidier interior appearance.

By upgrading your NA Miata’s exterior, you’re not only modernizing the car’s look but also improving its performance and functionality. Each of these mods, from body kits to lighting and wheels, can help create a Miata that’s uniquely yours. This mix of aesthetic and functional modifications brings out the best in the Miata, enhancing its classic design while adding a personal touch. So go ahead, get started with these mods, and make your NA Miata the roadster of your dreams.
