TC8-HDR4

Overview:

The ACT HD/Race Rigid 4 Pad Clutch Kit is engineered for serious enthusiasts and racers driving the Scion tC from 2011 to 2016. This clutch kit combines ACT’s renowned Heavy Duty pressure plate with a rigid 4-pad race disc, delivering aggressive engagement and enhanced clamp load for superior performance under demanding conditions. Designed to withstand high heat and stress, this kit is ideal for drivers seeking quicker shifts, improved durability, and a more direct driving experience on the track or spirited street use.

With a focus on maximizing clutch life and reliability, the ACT HD/Race kit offers a balance of moderate pedal effort and aggressive engagement, making it a perfect upgrade for those who want to push their Scion tC’s performance without sacrificing consistency.

Key Features:

This clutch kit incorporates advanced technology and materials to ensure top-tier performance and durability:

• Heavy Duty pressure plate featuring ACT’s exclusive diaphragm design for increased clamp load and reduced deflection
• Four-stage heat-treated diaphragms for enhanced strength and longevity
• Precision cover stampings to provide rigidity and consistent performance
• 4-pad rigid race disc constructed with high-quality ceramic friction materials for excellent heat tolerance
• Heat-treated chrome-moly hub for superior strength and durability
• Lightweight, rigid disc design enabling quicker shifts and smooth operation
• Harsher engagement suited for aggressive driving and racing applications
• 100% clamp load tested and dynamically computer balanced for smooth high-RPM reliability
• Backed by ACT’s industry-leading one-year warranty

Construction & Design:

The ACT HD/Race Rigid 4 Pad Clutch Kit is meticulously engineered with premium materials and precision manufacturing. The pressure plate’s diaphragm spring undergoes a rigorous four-stage heat treatment process, ensuring exceptional clamp force and resistance to fatigue. The cover is stamped with precision to maintain structural integrity and consistent performance throughout its lifespan.

The 4-pad rigid race disc features ceramic friction materials selected for their high heat tolerance and durability, making it well-suited for high-stress environments. Its chrome-moly hub is heat-treated to withstand the rigors of aggressive driving, while the lightweight design reduces rotational mass, contributing to faster engine response and shift times.

Performance & Sound

This clutch kit delivers a more aggressive engagement compared to stock setups, resulting in quicker, more precise shifts that enhance driving dynamics. The rigid 4-pad disc design may increase gear rattle and produce a firmer pedal feel, characteristics favored by racers and performance enthusiasts. While the engagement is harsher, the clutch’s design ensures reliable power transfer and extended friction life, thanks to ACT’s exclusive diaphragm technology.

Installation & Fitment:

The ACT HD/Race Rigid 4 Pad Clutch Kit is a direct fit for Scion tC models from 2011 through 2016. Installation typically requires standard clutch replacement procedures without the need for modifications. However, due to the aggressive nature of the rigid disc, some driveline noise and increased pedal effort should be expected. It is recommended that installation be performed by a qualified technician to ensure optimal performance and longevity.

What's Included:

• ACT Heavy Duty pressure plate with diaphragm spring
• Rigid 4-pad ceramic friction race disc with chrome-moly hub
• Installation hardware (where applicable)
• Detailed installation instructions

Ideal For:

This clutch kit is ideal for Scion tC owners who demand enhanced performance for light to moderate racing, autocross, or aggressive street driving. It suits drivers seeking faster shifts, increased clamp load, and a more direct clutch engagement. Due to its race-oriented design, it is recommended primarily for track use or performance applications rather than daily commuting.

ACT (Advanced Clutch Technology) engineers performance clutches and flywheels built for consistent engagement, higher torque capacity, and durability in street and race use. The brand emphasizes quality and reliability and is widely used by enthusiasts who need driveline components that can handle repeated hard launches, shifts, and track abuse.
