Top-Rated MX5 Parts to Upgrade Your Mazda’s Performance

The Mazda MX-5, often affectionately known as the Miata, has long been celebrated as one of the most engaging and fun-to-drive sports cars on the market. Since its debut in 1989, the MX-5 has captured the hearts of enthusiasts with its lightweight design, balanced handling, and spirited performance. However, even a car as iconic as the MX-5 can benefit from strategic upgrades to elevate its performance to new heights. Whether you’re a weekend warrior hitting the track, a daily driver looking for more thrill, or a dedicated tuner aiming to extract every ounce of power, investing in top-rated MX5 parts can transform your Mazda into a precision machine.

In this comprehensive guide, we’ll explore the best performance upgrades available for the MX-5 across its generations—NA, NB, NC, and ND. We’ll delve into categories like suspension, exhaust systems, brakes, intake and engine enhancements, and more. Drawing from expert recommendations and real-world user experiences, these upgrades not only boost horsepower and torque but also improve handling, braking, and overall driving dynamics. And when it comes to sourcing reliable components, look no further than specialists offering the Best MX5 Parts, where you’ll find a wide selection tailored to your Mazda’s needs.

Before diving in, it’s worth noting that performance upgrades should be approached thoughtfully. Consider your driving style, budget, and local regulations. Many of these parts are bolt-on for easy installation, but some may require professional tuning or alignment. Always prioritize quality to ensure safety and longevity. Now, let’s break down the top-rated MX5 parts that can supercharge your Mazda’s performance.

Suspension Upgrades: The Foundation of Better Handling

One of the first areas MX-5 owners target for upgrades is the suspension system. The stock setup is competent, but aftermarket options can dramatically sharpen cornering, reduce body roll, and provide a more connected feel to the road. Top-rated choices include coilover kits, sway bars, and bushings.

Coilovers are a standout upgrade, allowing adjustable ride height and damping for personalized setup. Brands like Bilstein, KW, and Ohlins offer kits specifically for the MX-5. For instance, the Bilstein B16 PSS10 coilover system is highly praised for its balance of comfort and performance. It features 10-way adjustable damping, enabling you to dial in stiffness for street or track use. Users report improved turn-in response and reduced dive under braking, making your Mazda feel more planted during aggressive maneuvers. Priced around £800-£1200, it’s a worthwhile investment for enthusiasts.

Sway bars, or anti-roll bars, are another essential. Upgrading to thicker bars from companies like Racing Beat or Hotchkis can minimize understeer and enhance neutrality. The Hotchkis Sport Sway Bar Set, for example, increases front bar diameter by 25% and rear by 50%, resulting in flatter cornering without sacrificing ride quality. Installation is straightforward, often taking just a few hours with basic tools.

Don’t overlook polyurethane bushings. Replacing rubber ones with stiffer polyurethane from Energy Suspension reduces flex in the chassis, leading to more precise steering. This upgrade is particularly beneficial for older NA and NB models where bushings may have deteriorated over time. Combined, these suspension mods can shave seconds off lap times and make everyday driving more exhilarating.

Exhaust Systems: Unleashing Power and Sound

A performance exhaust is one of the most popular MX-5 upgrades, offering gains in horsepower, torque, and that intoxicating exhaust note. The factory exhaust is restrictive to meet emissions standards, so aftermarket systems improve flow for better engine breathing.

Cat-back exhausts are a great starting point. The Borla Cat-Back Exhaust for the ND MX-5 is top-rated, delivering up to 10-15 horsepower gains while producing a deep, aggressive tone without drone. Constructed from stainless steel, it’s durable and corrosion-resistant. For NB and NC owners, the MagnaFlow Street Series provides similar benefits, with mandrel-bent tubing for optimal flow.

If you’re chasing more power, consider a full header-back system. Goodwin Racing’s RoadsterSport series is renowned among Miata communities for its lightweight design and tunable sound levels. Headers from brands like Cobalt or DC Sports replace the stock manifold, reducing backpressure and allowing the engine to rev freer. Expect 5-10% power increases, especially when paired with a tune.

Sound is subjective, but many owners appreciate the raspy growl these systems provide, enhancing the driving experience. Installation varies—cat-backs are DIY-friendly, while full systems might need a lift. Always check for compatibility with your model’s emissions requirements.

Braking Enhancements: Stopping Power for Confidence

Performance isn’t just about going faster; it’s about control. Upgrading brakes ensures you can harness that extra speed safely. The MX-5’s stock brakes are adequate, but for spirited driving or track days, bigger rotors and better pads are game-changers.

Big brake kits (BBKs) from Wilwood or StopTech are highly recommended. The Wilwood Superlite 4-Piston Kit for the MX-5 features larger vented rotors and multi-piston calipers, reducing fade and improving pedal feel. It’s lighter than stock, aiding unsprung weight reduction for better handling. Users rave about the shortened stopping distances—up to 20% in some tests.

For a budget-friendly option, upgrade to slotted or drilled rotors with performance pads. EBC’s Yellowstuff pads paired with their Ultimax rotors offer excellent bite and dust resistance. These are ideal for ND models, where the increased engine power in later versions demands more stopping capability.

Braided stainless steel brake lines from Goodridge eliminate sponginess, providing a firmer pedal. This mod is inexpensive (under £100) but transformative. Remember, proper bedding-in of new pads is crucial for optimal performance.

Intake and Engine Upgrades: Breathing Life into Your Powerplant

To squeeze more power from the MX-5’s naturally aspirated engine, focus on intake and engine components. Cold air intakes (CAIs) draw cooler, denser air, boosting throttle response and horsepower.

The K&N Typhoon Intake System is a top pick, adding 5-8 horsepower through its high-flow filter and heat shield. It’s CARB-legal in many regions and easy to install. For turbo aspirations, consider forced induction kits.

Superchargers and turbos take performance to another level. Rotrex supercharger kits from companies like Kraftwerks deliver 200+ horsepower reliably on stock internals. The TD04 turbo kit from BOFI Racing is favored for ND models, offering bolt-on installation and tunable boost levels up to 10 psi.

ECU tuning is essential with these mods. Systems like ECUtek or VersaTuner allow custom maps for optimized fuel and ignition timing. A tuned ND2 can hit 220 horsepower safely.

Other engine parts include lightweight flywheels (ACT or Fidanza) for quicker revs and oil coolers for sustained track performance.

Wheels, Tires, and Aerodynamics: The Finishing Touches

No performance build is complete without wheels and tires. Lightweight alloys from Enkei or OZ Racing reduce rotational mass, improving acceleration and handling. Pair them with sticky tires like Michelin Pilot Sport 4S for ultimate grip.

Aerodynamic add-ons, such as splitters and spoilers, enhance downforce. The APR GTC-200 wing provides adjustable angles for track tuning.

Conclusion: Elevate Your MX-5 Experience

Upgrading your Mazda MX-5 with these top-rated parts can turn a great car into an extraordinary one. From suspension tweaks for razor-sharp handling to exhaust and engine mods for raw power, the possibilities are endless. Start small or go all-in—either way, you’ll rediscover the joy of driving.
