The Mazda Miata has long been celebrated as one of the best roadsters on the market, offering a perfect blend of agility, fun, and a timeless design. The Best Miata NB Modifications (1999-2005) model, often referred to as the second-generation Miata, is particularly loved for its light weight, rear-wheel drive setup, and responsive handling. However, for those who want to take their Miata NB to the next level, modifications are key to enhancing performance, aesthetics, and overall driving experience.
In this guide, we’ll explore some of the best Miata NB modifications that every enthusiast should consider, from boosting engine power to improving handling and giving your Miata a unique visual style. Whether you’re a weekend driver or a track-day enthusiast, these modifications can significantly improve your Best Miata NB Modifications performance and appeal.
Performance Modifications for Miata NB
Cold Air Intake
One of the easiest ways to improve the engine’s performance in your Best Miata NB Modifications is by installing a cold air intake (CAI). The Miata NB’s stock intake system is restrictive, and a CAI allows the engine to breathe in colder, denser air. This can lead to improved throttle response, better acceleration, and increased horsepower. Popular options for the Best Miata NB Modifications include brands like K&N and AEM, both of which offer high-quality filters that improve air flow while keeping out contaminants.
Aftermarket Exhaust System
Upgrading the exhaust system is one of the most common and effective performance modifications for the Miata NB. A new cat-back exhaust can not only free up horsepower by reducing backpressure but also enhance the car’s aggressive sound. Brands like Borla, Flyin’ Miata, and MX5 Miata offer exhaust systems specifically designed for the Best Miata NB Modifications. Additionally, going for a header upgrade can provide even more gains in horsepower by improving exhaust flow.
Forced Induction: Turbocharging or Supercharging
For those looking for a significant increase in horsepower, adding forced induction is one of the best Miata NB modifications. Turbochargers or superchargers will significantly boost engine performance, taking your Miata from a modest 140-155 horsepower to over 200 horsepower or more, depending on the setup. Popular kits for the Miata NB include:
- Flyin’ Miata Turbo Kit: Known for its reliability and performance, this kit can offer 200+ horsepower while maintaining the Miata’s responsive handling.
- Jackson Racing Supercharger: A supercharger provides immediate torque and a smoother power delivery compared to a turbocharger, making it an excellent choice for daily driving and spirited driving.
Both options can completely transform your Best Miata NB Modifications performance, turning it into a true powerhouse.
Upgraded ECU Tuning
After upgrading intake, exhaust, or forced induction components, it’s crucial to optimize the car’s performance with an ECU tune. By reprogramming the engine control unit (ECU), you can fine-tune your Miata’s air-fuel ratio, ignition timing, and boost levels (if forced induction is involved). This modification ensures that the engine is running at its optimal efficiency, maximizing the performance gains from other modifications.
Lightweight Flywheel
Replacing the stock flywheel with a lightweight flywheel is a common modification for Best Miata NB Modifications owners who want to improve engine response and throttle feel. A lightweight flywheel reduces rotational mass, making it easier for the engine to rev up and respond to throttle input. This leads to quicker acceleration and improved overall driving dynamics, particularly in spirited driving situations.
Suspension and Handling Modifications
Coilovers or Upgraded Shocks and Springs
Best Miata NB Modifications owners are often looking for better handling and responsiveness. Coilovers are one of the most popular suspension upgrades, offering the ability to adjust ride height and damping settings to suit your driving style. Brands like BC Racing, Tein, and Koni offer coilover kits specifically designed for the Miata NB. If you’re not looking to go the full coilover route, upgrading to performance shocks and lowering springs is an excellent option to improve handling without breaking the bank.
A stiffer suspension setup can drastically improve cornering capabilities and reduce body roll, allowing for more precise control during high-speed turns. Additionally, lowering the car’s ride height can lower the center of gravity, which further enhances handling.
Sway Bars
Upgrading the sway bars (also known as anti-roll bars) is another modification to consider for improving the Best Miata NB Modifications handling. A larger or stiffer rear sway bar can reduce body roll and improve balance, while a front sway bar upgrade can increase front-end grip and reduce understeer. Brands like Progress Technology and Racing Beat offer excellent sway bar options for the Miata NB.
Strut Tower Brace
For those looking to increase chassis rigidity and improve steering response, a strut tower brace is a simple yet effective modification. A strut tower bar connects the two front strut towers, reducing flex and improving the car’s steering feel. This mod is especially beneficial during track days or autocross events where precise handling is essential.
Brake System Upgrades
Upgraded Brake Pads and Rotors
One of the most important modifications for any car that will be driven hard or on a track is upgrading the brake pads and rotors. The stock brake system on the Best Miata NB Modifications is sufficient for everyday driving, but for enthusiasts who plan to push the car’s limits, upgraded pads and rotors are a must. High-performance pads like Hawk HP+ or Ferodo DS2500 provide better stopping power and fade resistance.
In addition to pads, upgrading to slotted or drilled rotors improves heat dissipation and enhances braking performance. Wilwood and StopTech are trusted brands that offer high-performance rotors and caliper kits.
Stainless Steel Brake Lines
Upgrading to stainless steel brake lines is another excellent modification that improves brake feel and performance. Stainless steel lines are more resistant to expansion under pressure compared to stock rubber brake lines, providing a firmer and more responsive pedal feel, particularly in high-performance driving situations.
Aesthetic Modifications
Custom Wheels and Tires
The Best Miata NB Modifications is an incredibly agile car, and customizing its wheels can greatly enhance both its appearance and handling. Lightweight alloy wheels are a popular modification choice. By choosing wheels that are lighter than the stock ones, you reduce unsprung weight, which improves handling and acceleration. Popular wheel brands for the Miata NB include Enkei, Rays, and OZ Racing.
When upgrading your wheels, it’s important to also consider the tires. High-performance summer tires like Michelin Pilot Sport or Bridgestone Potenza can drastically improve grip, especially when combined with lightweight wheels.
Body Kits and Aero Enhancements
If you’re looking to give your Best Miata NB Modifications sportier or more aggressive look, consider adding a body kit or aero enhancements like a front lip or rear spoiler. These modifications not only improve the appearance of your Miata but can also provide additional downforce at high speeds, improving stability. Many aftermarket manufacturers like Flyin’ Miata and Mazdaspeed offer custom body parts that complement the Miata’s design while enhancing its performance.
Roll Bars and Racing Seats
For a track-focused Miata NB, consider adding a roll bar for safety and a pair of racing seats to reduce weight and improve driving comfort. Hard Dog is a reputable brand that makes high-quality roll bars for Miatas, while Recaro and Sparco offer top-tier racing seats for better support during spirited driving.
Interior Modifications
Short Shifter
A short shifter is a must-have modification for Best Miata NB Modifications owners who want a more connected driving experience. This modification reduces the throw distance between gears, providing quicker, more precise shifts. Kartboy and Racing Beat are popular brands that offer short shifters that fit Miata NB models perfectly.
Lightweight Carpet and Sound Deadening Removal
For those aiming to reduce weight, removing unnecessary interior materials like the carpet or sound deadening can make a noticeable difference. This can improve the car’s responsiveness, especially on the track. Just be aware that this modification will increase road noise and may affect the comfort level for daily driving.
Conclusion: Elevate Your Miata NB with the Right Modifications
