Key Features:

Built with advanced materials and precision engineering, the ACT XT/Race Rigid 4 Pad Clutch Kit offers the following key benefits:

• Xtreme pressure plate with exclusive diaphragm design for increased clamp load and reduced deflection
• Four-stage heat-treated diaphragms for superior strength and longevity
• Precision cover stampings enhance rigidity and ensure consistent performance
• 4-pad rigid race disc constructed with high-quality ceramic friction materials for excellent heat tolerance
• Heat-treated chrome-moly hub for enhanced strength and durability
• Lightweight, rigid disc design promotes faster shifts and smooth operation
• Moderate to heavy pedal effort with aggressive engagement suited for race conditions
• 100% clamp load tested and dynamically computer balanced for high RPM reliability
• Extended friction life supported by ACT’s exclusive diaphragm design

Construction & Design

The ACT XT/Race kit is meticulously engineered to deliver maximum performance and durability. The Xtreme pressure plate utilizes a unique diaphragm spring design that increases clamp load while minimizing deflection, which helps extend clutch life under extreme conditions. Each diaphragm undergoes a rigorous four-stage heat treatment process to ensure consistent strength and reliability.

The clutch disc features a rigid 4-pad layout with premium ceramic friction materials selected for their high heat tolerance and consistent engagement characteristics. The chrome-moly hub is heat-treated to withstand the stresses of aggressive driving, while the lightweight design reduces rotational mass, allowing for quicker throttle response and smoother shifting.

Performance & Sound

This clutch kit is designed for aggressive engagement, resulting in a harsher pedal feel and increased gear rattle compared to stock setups. The rigid 4-pad disc promotes faster, more precise shifts, making it ideal for track and race environments where quick gear changes are essential. While engagement is firm, the clutch maintains smooth operation and reliable power transfer at high RPMs.

Installation & Fitment

The ACT XT/Race Rigid 4 Pad Clutch Kit is a direct fit replacement for the 2011–2016 Scion tC, requiring no modifications for installation. It is recommended that installation be performed by a professional or experienced technician to ensure proper alignment and optimal performance. This kit is intended for race use only and may not be suitable for daily driving due to its aggressive engagement and pedal effort.

What’s Included

• Xtreme pressure plate with diaphragm spring
• Rigid 4-pad ceramic friction clutch disc
• Heat-treated chrome-moly hub
• Installation hardware (where applicable)
