Track-ready Wrx Clutch Upgrade: Upgrades for Improved Heat Resistance and Durability

by

The Subaru WRX is renowned for its performance and handling, especially on the track. However, as enthusiasts push their vehicles to the limit, the need for a reliable clutch system becomes paramount. Upgrading to a track-ready clutch can significantly enhance heat resistance and durability, ensuring that your WRX performs at its best under extreme conditions.

Understanding Clutch Upgrades

A clutch upgrade is essential for those who regularly participate in track events. The stock clutch may not withstand the rigors of high-performance driving, leading to slippage, overheating, and premature wear. Upgrading to a performance clutch can provide several benefits, including:

  • Increased heat resistance
  • Improved durability
  • Better engagement and disengagement
  • Enhanced power transfer

Key Features of Track-Ready Clutches

When selecting a clutch for track use, consider the following key features that contribute to improved performance:

  • Material Composition: High-performance clutches often utilize advanced materials such as ceramic or carbon composite, which can withstand higher temperatures and resist wear.
  • Clamping Force: Increased clamping force helps to prevent slippage under high torque conditions, ensuring that power is effectively transferred to the wheels.
  • Disc Design: Multi-disc setups can provide greater surface area for friction, enhancing grip and durability.
  • Flywheel Compatibility: Upgrading to a lightweight flywheel can improve throttle response and reduce rotational mass, further enhancing performance.

Several brands offer high-performance clutch kits specifically designed for the Subaru WRX. Here are some popular options:

  • Exedy Stage 1 Clutch Kit: Known for its high torque capacity and smooth engagement, this kit is ideal for street and occasional track use.
  • ACT Heavy Duty Clutch Kit: This kit features a higher clamping force and is designed for those who demand more from their WRX during track events.
  • Clutch Masters FX400: A multi-disc clutch that offers exceptional heat resistance and durability, perfect for serious track enthusiasts.
  • Competition Clutch Stage 3: This kit is designed for high-performance applications, providing excellent grip and heat management.

Installation Considerations

Installing a new clutch can be a complex process that requires specific tools and expertise. Here are some considerations to keep in mind:

  • Professional Installation: It is recommended to have a professional mechanic perform the installation to ensure proper alignment and torque specifications.
  • Break-In Period: Many performance clutches require a break-in period to optimize performance and longevity. Follow the manufacturer’s guidelines carefully.
  • Supporting Modifications: Consider upgrading other components such as the flywheel, transmission fluid, and shifter bushings to complement your new clutch.

Maintaining Your Upgraded Clutch

Once you have upgraded your WRX’s clutch, proper maintenance is essential to ensure its longevity and performance. Here are some tips:

  • Regular Inspections: Check for signs of wear, such as unusual noises or difficulty engaging gears.
  • Fluid Changes: Maintain proper transmission fluid levels and change the fluid as recommended by the manufacturer.
  • Avoid Overheating: Use proper driving techniques to prevent overheating the clutch, especially during track events.

Conclusion

Upgrading to a track-ready clutch for your Subaru WRX can significantly enhance its performance by improving heat resistance and durability. By selecting the right components and ensuring proper installation and maintenance, you can enjoy a more reliable and exhilarating driving experience on the track.
