Construction & Design:
The ACT Race Rigid 4 Pad Clutch Kit is meticulously engineered for maximum performance and durability. The Heavy Duty pressure plate features a unique diaphragm spring design that increases clamp load while minimizing deflection, which helps extend clutch life and maintain consistent engagement. Each diaphragm undergoes a rigorous four-stage heat treatment process to ensure exceptional strength and reliability under extreme conditions.
The clutch disc itself is built with a rigid 4-pad ceramic friction material that offers high heat resistance and aggressive engagement characteristics. The chrome-moly hub is heat-treated to withstand the stresses of racing and high-performance driving, providing long-lasting durability. The lightweight design reduces rotational mass, allowing for quicker throttle response and faster shifts.
Performance & Sound
This clutch kit delivers a harsher engagement compared to stock setups, which translates to faster and more precise shifts favored in racing scenarios. Drivers can expect increased gear rattle typical of rigid disc designs, which is a trade-off for the enhanced performance and quicker clutch response. Pedal effort remains light to moderate, making it manageable for daily driving while still offering aggressive engagement for spirited use.
Installation & Fitment:
The ACT Race Rigid 4 Pad Clutch Kit is a direct fit for 2004 to 2006 Scion xA and xB models, designed to replace the factory clutch without requiring modifications. Installation should be performed by a qualified technician to ensure proper alignment and optimal performance. The kit is recommended for race use only due to its aggressive engagement characteristics and potential for increased spline wear.
