Construction & Design:
The XT/Race kit features a robust construction that prioritizes strength and precision. The pressure plate’s diaphragm is engineered through a meticulous four-stage heat-treating process, ensuring exceptional clamp load and resistance to fatigue. This design minimizes deflection, which helps maintain consistent pedal feel and clutch engagement over time.
The clutch disc utilizes a rigid 4-pad layout with premium ceramic friction materials that provide high heat tolerance and reliable grip during aggressive driving. The chrome-moly hub is heat-treated to withstand the stresses of racing environments, reducing the risk of failure and extending service life. The overall lightweight and rigid design contributes to faster shifts and improved throttle response, critical for competitive driving scenarios.
Performance & Sound
The XT/Race clutch kit delivers a notably harsher engagement compared to stock or street-oriented clutches, which translates to quicker and more precise shifts. This aggressive engagement is ideal for drivers who prioritize performance and control on the track. While the pedal effort is moderate to heavy, the clutch’s design ensures consistent power transfer and reduced slippage under high torque loads.
Expect increased gear rattle typical of rigid race discs, which is a trade-off for the enhanced shift speed and clutch responsiveness. This characteristic sound is often welcomed by enthusiasts as a sign of a serious performance upgrade.
Installation & Fitment:
This clutch kit is a direct fit for the following vehicles without requiring modifications: 2013–2016 Scion FR-S, 2013–2020 Subaru BRZ, and 2017–2020 Toyota 86. Installation should be performed by a qualified technician familiar with performance clutch systems to ensure proper setup and adjustment. Due to the aggressive nature of the XT/Race clutch, it is recommended for vehicles used primarily in racing or high-performance driving environments.
