SB8-XTG4

Overview:

The ACT XT/Race Sprung 4 Pad Clutch Kit is engineered for drivers who demand aggressive performance and reliability from their clutch system. Designed specifically for the Scion FR-S (2013–2016), Subaru BRZ (2013–2020), and Toyota 86 (2017–2020), this kit delivers a robust solution for high horsepower street and race applications. Featuring ACT’s exclusive Xtreme pressure plate and a spring-centered 4-pad race disc, it offers enhanced clamp load, reduced deflection, and superior clutch life under demanding conditions.

This clutch kit is ideal for enthusiasts seeking a balance between aggressive engagement and durability, providing quicker shifts and improved drivability without sacrificing reliability. Whether on the street or the track, the ACT XT/Race Sprung kit ensures consistent performance and smooth operation at high RPMs.

Key Features:

The ACT XT/Race Sprung 4 Pad Clutch Kit incorporates advanced technology and precision engineering to meet the needs of performance drivers. Key features include:

• Xtreme pressure plate with exclusive diaphragm design for increased clamp load and reduced deflection
• Four-stage heat-treated diaphragms for enhanced durability and consistent performance
• Precision cover stampings that provide rigidity and maintain consistent clamp force
• 4-pad spring-centered race disc designed to damp torsional vibrations for quieter operation
• Wraparound spring windows and thicker retainer stampings for improved spring support and reliability
• Spring-centered disc construction that resists failure under harsh conditions
• Use of select ceramic friction materials for high heat tolerance and extended friction life
• Moderate to heavy pedal effort with aggressive engagement for faster shifting
• 100% clamp load tested and dynamically computer balanced for smooth, high RPM reliability

Construction & Design:

The ACT XT/Race Sprung clutch kit is built with precision and durability in mind. The pressure plate features a unique diaphragm spring design that undergoes a rigorous four-stage heat treatment process, ensuring superior strength and longevity. This design increases clamp load while minimizing deflection, which translates to better pedal feel and clutch engagement.

The 4-pad spring-centered race disc is engineered to handle the torsional vibrations common in high-performance driving. Its spring retainers are reinforced with wraparound windows and thicker stampings, reducing stress concentrations and enhancing overall strength. The ceramic friction material selected for the disc offers excellent heat resistance, maintaining consistent performance even under extreme conditions.

Performance & Sound

The XT/Race Sprung clutch kit provides a more aggressive engagement compared to stock clutches, resulting in faster, more precise shifts. While the engagement is harsher, it is well-suited for spirited street driving and track use where quick throttle response is essential. The spring-centered design helps dampen vibrations, reducing gear rattle and noise typically associated with race-oriented clutches, offering a balance between performance and drivability.

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. It is designed to work seamlessly with the factory flywheel and transmission setup. Installation should be performed by a qualified technician to ensure proper clutch alignment and optimal performance.

What's Included:

• Xtreme pressure plate with diaphragm spring
• 4-pad spring-centered race disc with ceramic friction material
• Spring retainers with reinforced wraparound windows
• Installation hardware as required

Ideal For:
