SB13-HDG6

Overview:

The ACT HD/Race Sprung 6 Pad Clutch Kit is engineered for drivers seeking a robust, high-performance clutch solution for their Scion FR-S, Subaru BRZ, or Toyota 86. Designed to handle increased horsepower and aggressive driving conditions, this kit features ACT’s renowned Heavy Duty pressure plate combined with a 6-pad sprung race disc. It delivers a balance of durability, heat tolerance, and precise engagement, making it ideal for both spirited street driving and competitive racing environments.

With its advanced diaphragm design and spring-centered disc, this clutch kit offers improved clamp load and reduced deflection, resulting in extended clutch life and consistent performance under demanding conditions. Whether upgrading for track use or enhancing daily driving performance, the ACT HD/Race Sprung 6 Pad Clutch Kit provides reliable, aggressive engagement with moderate pedal effort.

Key Features:

This clutch kit incorporates several advanced technologies and design elements to optimize performance and durability:

• Heavy Duty 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
• 6-pad spring-centered race disc designed to damp torsional vibrations and resist failure under harsh conditions
• Wraparound spring windows and thicker retainers provide enhanced spring support and reduce stress concentrations
• Use of select ceramic friction materials for high heat tolerance and maximum performance
• Light to moderate pedal effort with aggressive clutch engagement for faster shifting
• Recommended for larger clutch sizes to better absorb heat during high-load applications
• 100% clamp load tested and dynamically computer balanced for smooth operation at high RPMs
• Backed by ACT’s industry-leading one-year warranty

Construction & Design:

The ACT HD/Race Sprung 6 Pad Clutch Kit is meticulously engineered with premium materials and precision manufacturing processes. The Heavy Duty pressure plate features a diaphragm spring that undergoes a rigorous four-stage heat treatment to enhance durability and clamp force consistency. This design reduces deflection, ensuring the clutch maintains optimal contact and performance over time.

The 6-pad sprung race disc incorporates a spring-centered hub to effectively dampen torsional vibrations, reducing the risk of premature failure during aggressive driving. The wraparound spring windows and reinforced retainers increase the strength and reliability of the springs, allowing the clutch to withstand the rigors of both street and track use. The ceramic friction material is selected for its ability to tolerate high temperatures while delivering consistent engagement and friction life.

Performance & Sound

The engagement of the 6-pad sprung race disc is notably more aggressive than standard clutch discs, providing quicker and more precise shifts. While this results in a harsher engagement feel, it significantly improves throttle response and power transfer, especially in high horsepower applications. The clutch produces an OE to mild gear rattle sound, which is typical for performance-oriented sprung hub designs and does not affect reliability.

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 alignment and torque specifications. The kit replaces the factory clutch assembly and is compatible with stock flywheels, although resurfacing the flywheel is recommended for optimal performance and longevity.

What's Included:

• ACT Heavy Duty diaphragm pressure plate
• 6-pad sprung race clutch disc with ceramic friction material
• Spring retainers with wraparound spring windows
• Installation hardware (where applicable)
• Detailed installation instructions

Ideal For:

The ACT HD/Race Sprung 6 Pad Clutch Kit is ideal for enthusiasts and racers who demand a durable, high-performance clutch capable of handling increased power and aggressive driving. It suits high horsepower street vehicles, track day cars, and mild to moderate race applications where quick shifting and reliable engagement are critical. Drivers looking to upgrade from the factory clutch for improved heat tolerance and clutch life will find this kit an excellent choice.

ACT (Advanced Clutch Technology) engineers performance clutches and flywheels built for consistent engagement, higher torque capacity, and durability in street and race use.
