What is the primary benefit of a twin disc clutch over a single disc?

A twin disc clutch uses two friction surfaces instead of one. This larger total friction area allows it to handle significantly more torque and dissipate heat more effectively, making it ideal for high-horsepower or track-focused vehicles.

Does this kit include everything needed for installation?

This kit includes the twin disc clutch assembly and a steel flywheel. It is recommended to consult the manufacturer's installation guide to confirm if any additional pilot bearings, alignment tools, or release bearings are required for your specific vehicle.

What is the break-in procedure for this clutch kit?

Race clutch kits often require a specific break-in period to ensure the friction surfaces mate properly. Always refer to the Clutch Masters installation instructions included with the kit for the recommended break-in procedure to ensure optimal performance and longevity.

About this part

Product Details

This Clutch Masters 8.5-inch Race Twin Disc Clutch Kit is built for the 2004-2011 Subaru WRX STi with the 2.5L turbocharged engine and 6-speed transmission. It's a push-type clutch designed for high-performance applications where a stock clutch just won't hold. If you're pushing significant power or plan on track use, this kit offers the robust engagement and torque capacity you need.

This kit features two friction discs, providing a larger surface area for engagement compared to a single disc setup. This increased surface area is key to handling higher torque loads without excessive slipping or premature wear. The steel flywheel included is a solid foundation for the twin-disc assembly, ensuring a stable platform for power transfer. Clutch Masters uses well-built components throughout this kit, aiming for reliable performance under demanding conditions. The push-type design is specific to certain transmission configurations, so ensure this matches your WRX STi's setup.

When installing a twin-disc clutch, especially a race-oriented one like this, it's important to follow the manufacturer's detailed instructions carefully. Proper alignment and break-in procedures are crucial for longevity and optimal performance. This kit is a significant upgrade for those looking to maximize their WRX STi's drivetrain capability.
