The Mazda Miata NA has earned its place as one of the most beloved sports cars of all time. Known for its lightweight frame, precise handling, and pure driving pleasure, this roadster has remained a favorite among enthusiasts since its debut. But for many, the real fun begins when you start adding performance parts that unlock its full potential. If you’re looking to enhance your Mazda Miata NA’s performance, this guide will walk you through the best upgrades to improve speed, handling, braking, and overall driving experience.

Engine Performance Upgrades
Cold Air Intake Systems: Breathe Easy for More Power
One of the simplest and most effective ways to boost your Miata NA’s performance is by upgrading the air intake system. A cold air intake allows cooler, denser air into your engine, which improves combustion efficiency. This results in more horsepower, better throttle response, and a noticeable increase in acceleration.
Real-life example: Picture yourself on a Sunday drive, hitting the gas pedal and feeling that instant surge of power as the Miata roars to life. That’s the magic of a cold air intake. Brands like K&N and AEM offer high-quality intakes that are easy to install and deliver real-world gains.
Aftermarket Exhaust Systems: Let Your Miata Sing
For enthusiasts who want their car to sound as good as it drives, an aftermarket exhaust system is a must. Replacing the stock exhaust with a performance exhaust not only gives your Miata NA a more aggressive, sporty sound but also improves exhaust flow. This leads to gains in both horsepower and torque.
Imagine the deep growl of a Borla exhaust as you blast through backroads. The sound alone can transform your driving experience, but the added power makes it all the more thrilling.
ECU Tuning: Unlock Hidden Power
Your Miata’s stock engine control unit (ECU) is programmed for a balance between performance and efficiency. But with ECU tuning, you can adjust the car’s fuel and ignition mapping to unleash hidden power. This modification is particularly effective when combined with other upgrades like a cold air intake and exhaust system.
ECU tuning allows you to fine-tune your engine’s performance to match your driving style, whether you want maximum power on the track or smoother acceleration for daily driving.
Suspension and Handling Improvements
Coilover Kits: Master Every Corner
When it comes to handling, the Miata NA is already known for its nimble feel. However, installing a set of coilovers can take things to the next level. Coilovers give you the ability to adjust both ride height and damping, allowing you to fine-tune the suspension for improved cornering and road feedback.
Imagine flying through tight corners on a twisty mountain road, your Miata feeling planted and composed with every turn. That’s the difference a quality coilover setup can make. Popular brands like KW, BC Racing, and Tein offer kits that cater to both daily driving and track use.
Sway Bars and Strut Braces: Tighten Up Your Ride
Upgrading to thicker sway bars reduces body roll, making your Miata feel more stable during hard cornering. Pairing this with strut braces, which stiffen the chassis, further improves handling by increasing structural rigidity.
The result? You can push your Miata harder through corners without sacrificing control, giving you a more responsive and engaging driving experience.
Braking System Upgrades
Performance Brake Pads: Stop on a Dime
If you’re planning to increase your Miata’s speed and handling, upgrading the braking system is essential. Performance brake pads provide better stopping power and improved fade resistance, especially during high-performance driving.
Whether you’re carving through a mountain pass or taking your Miata to the track, performance brake pads ensure that your car stops just as quickly as it accelerates.
Big Brake Kits: Power Meets Control
For those who demand serious braking power, a big brake kit is the ultimate upgrade. These kits offer larger rotors and calipers, providing more braking surface area and reducing brake fade during prolonged hard braking sessions.
While these may be overkill for a daily driver, they’re a game-changer for anyone looking to take their Miata NA to the track.
Wheels and Tires: Grip and Go
Lightweight Wheels: Shed Pounds, Gain Speed
Switching to lightweight wheels can improve both your Miata’s acceleration and braking by reducing unsprung weight. Lightweight wheels also enhance handling, as they make it easier for the suspension to react to the road surface.
Brands like Enkei and OZ Racing are popular choices among Miata owners for their combination of durability and reduced weight. Not only do they improve performance, but they also give your Miata a stylish edge.
Performance Tires: Where the Rubber Meets the Road
Your Miata’s tires are the only part of the car that touches the road, making them one of the most important performance upgrades. Performance tires offer better grip, especially during hard cornering and acceleration.
If you want to get the most out of your Miata’s handling, investing in a set of summer performance tires can make all the difference. For everyday driving, high-performance all-season tires are a good compromise between grip and durability.
Interior and Exterior Performance Mods
Bucket Seats: Stay Planted
As fun as it is to throw your Miata through corners, sliding around in the driver’s seat can get old fast. Bucket seats provide better lateral support, keeping you planted during spirited driving. They also add a race-inspired look to your Miata’s interior.
Whether you’re doing autocross or just enjoying a spirited backroad drive, bucket seats make sure you stay in control.
Aerodynamics: Front Splitters and Rear Spoilers
If you’re looking for that extra edge in stability at higher speeds, consider adding aerodynamic components like a front splitter or rear spoiler. These parts create downforce, helping your Miata stay grounded as you push it to its limits.
Conclusion: Building Your Perfect Mazda Miata NA
The Mazda Miata NA is a platform that begs for customization. Whether you’re looking for more speed, better handling, or just a more enjoyable driving experience, the right performance parts can transform your Miata into a car that’s uniquely yours.
From engine upgrades like cold air intakes and exhaust systems to handling improvements like coilovers and sway bars, there’s no shortage of options to suit your driving style. The best part? You can start small and build your way up, tailoring your upgrades to match your budget and performance goals.
With the right combination of performance parts, your Mazda Miata NA will be ready to tackle anything the road throws its way, whether that’s a weekend track day or your favorite stretch of twisty backroads.
