Supporting Mods for Daily-driven Rx-7 Ls Swap: Clutch, Brakes, and Suspension Upgrades

by

The Mazda RX-7 is a beloved sports car known for its lightweight chassis and rotary engine. However, many enthusiasts are opting for an LS swap to enhance performance and reliability. When undertaking this modification, it’s crucial to consider supporting mods that ensure the vehicle remains a daily driver. This article explores essential upgrades for the clutch, brakes, and suspension to complement an RX-7 LS swap.

Clutch Upgrades

One of the first components that need attention in an RX-7 LS swap is the clutch. The stock clutch may not handle the increased power and torque of the LS engine, leading to premature wear or failure. Upgrading the clutch is essential for reliable performance.

  • Performance Clutch Kits: Consider a high-performance clutch kit designed to handle the increased power of the LS engine. Brands like Exedy and Spec offer options tailored for this swap.
  • Lightweight Flywheel: Upgrading to a lightweight flywheel can improve throttle response and reduce rotational mass, enhancing acceleration.
  • Hydraulic Clutch Conversion: If the RX-7 is still using the factory cable clutch, a hydraulic conversion can provide smoother engagement and better pedal feel.

Brake Upgrades

With the added power from an LS engine, the stock brakes may struggle to provide adequate stopping power. Upgrading the braking system is vital for safety and performance.

  • Big Brake Kits: Invest in a big brake kit that includes larger rotors and calipers. Brands like Wilwood and Baer offer kits specifically for the RX-7.
  • High-Performance Brake Pads: Use high-performance brake pads that can withstand higher temperatures and provide better bite.
  • Stainless Steel Brake Lines: Upgrading to stainless steel brake lines can improve pedal feel and reduce brake line expansion under pressure.

Suspension Upgrades

A proper suspension setup is crucial for handling and ride quality, especially with the added weight of an LS engine. Upgrading the suspension will enhance the driving experience and ensure the RX-7 remains enjoyable on daily drives.

  • Coilover Kits: Consider a quality coilover kit that allows for adjustable ride height and damping. Brands like BC Racing and KW offer excellent options for the RX-7.
  • Upgraded Sway Bars: Installing stiffer sway bars can reduce body roll and improve cornering stability.
  • Performance Bushings: Replace old rubber bushings with performance polyurethane bushings for better handling and responsiveness.

Conclusion

Upgrading the clutch, brakes, and suspension are essential steps in making an RX-7 LS swap a reliable daily driver. By investing in quality components, you can enhance performance and ensure that your RX-7 remains enjoyable on the road. Whether you’re commuting or hitting the track, these supporting mods will make a significant difference in your driving experience.
