The Mazda RX-7 FD is a legendary sports car known for its lightweight design and rotary engine. For enthusiasts looking to enhance their track performance, there are several modifications that can significantly improve handling, power, and overall driving experience. This article explores the best performance mods for the FD RX-7, focusing on suspension upgrades and power enhancements.
Suspension Upgrades
One of the most critical aspects of performance driving is suspension. Upgrading the suspension can lead to better handling, improved stability, and enhanced driver feedback. Here are some of the top suspension modifications for the FD RX-7.
- Coilovers: Upgrading to adjustable coilovers allows drivers to fine-tune ride height and damping settings for optimal track performance.
- Anti-Roll Bars: Stiffer anti-roll bars help reduce body roll during cornering, providing more predictable handling.
- Upgraded Bushings: Replacing worn rubber bushings with polyurethane options improves responsiveness and reduces flex in the suspension components.
- Strut Braces: Adding front and rear strut braces increases chassis rigidity, enhancing cornering stability.
Power Enhancements
To maximize the potential of the RX-7’s rotary engine, various performance modifications can be made to increase horsepower and torque. Below are some of the most effective power enhancements.
- Aftermarket Turbocharger: Upgrading to a larger turbocharger can significantly increase power output, especially when paired with proper tuning.
- Intake and Exhaust Systems: A high-flow intake and exhaust system reduce back pressure and improve airflow, leading to better engine performance.
- ECU Tuning: Custom ECU tuning optimizes engine parameters for maximum performance, especially after modifications.
- Intercooler Upgrade: A larger intercooler helps keep intake temperatures down, improving efficiency and power during track use.
Brake System Improvements
Performance modifications should also extend to the braking system. Enhancing the brakes ensures that the car can handle the increased speeds and demands of track driving.
- Upgraded Brake Pads: High-performance brake pads provide better stopping power and fade resistance during intense driving.
- Slotted or Drilled Rotors: These rotors improve heat dissipation and reduce brake fade, enhancing overall braking performance.
- Stainless Steel Brake Lines: Upgrading to stainless steel lines improves brake feel and reduces flex under hard braking.
- Brake Fluid: Using high-temperature brake fluid can prevent brake fade during extended track sessions.
Weight Reduction Techniques
Reducing weight can dramatically improve the performance of the RX-7. Here are some effective methods to shed pounds from the vehicle.
- Lightweight Wheels: Switching to lightweight wheels reduces unsprung mass, improving handling and acceleration.
- Carbon Fiber Components: Replacing stock parts with carbon fiber options, such as hoods and spoilers, significantly reduces weight.
- Interior Stripping: Removing unnecessary interior components can lower weight, but consider the impact on comfort and usability.
- Battery Relocation: Moving the battery to a lighter location can improve weight distribution and lower overall weight.
Final Thoughts
The Mazda RX-7 FD is a fantastic platform for track enthusiasts looking to enhance their driving experience. By focusing on suspension upgrades, power enhancements, brake improvements, and weight reduction, drivers can unlock the full potential of this iconic sports car. Each modification should be carefully considered based on personal driving style and track requirements to achieve the best results.
