Construction & Design:
The ACT XT/Race clutch kit is built with precision engineering and premium materials to meet the demands of high-performance driving. The pressure plate features an exclusive diaphragm design that undergoes a rigorous four-stage heat treatment process, ensuring exceptional strength and longevity. This design increases clamp load while minimizing deflection, which translates to improved clutch life and consistent engagement.
The 4-pad rigid race disc uses select ceramic friction materials known for their high heat tolerance and durability. Its chrome-moly hub is heat-treated to withstand the stresses of aggressive driving, while the lightweight and rigid construction allows for faster, more precise shifts. This combination of materials and design elements results in a clutch kit that balances performance with reliability.
Performance & Sound
The XT/Race 4-pad rigid disc delivers a harsher engagement compared to stock clutches, providing immediate power transfer and quicker shifts essential for competitive driving. While this aggressive engagement may increase gear rattle and pedal effort, it ensures that power is efficiently transmitted without slippage under high load conditions. Drivers can expect a more connected and responsive feel, making it ideal for track and race environments.
Installation & Fitment:
This clutch kit is a direct fit for the Scion FR-S (2013–2016), Subaru BRZ (2013–2020), and Toyota 86 (2017–2020) models, requiring no modifications for installation. Professional installation is recommended to ensure proper clutch adjustment and optimal performance. Due to the aggressive nature of the clutch engagement, some drivability changes such as increased pedal effort and gear rattle may be experienced.
