- Dual clamp load heavy-duty pressure plate engineered for maximum clamp force and reliability
- Aggressive on/off clutch engagement with minimal chatter for precise control
- Unsprung design that reduces rotating mass, improving throttle response and acceleration
- Engineered specifically for the Subaru BRZ’s FA20 engine and rear-wheel-drive setup
- Quality checked and signed off by expert engineers with over 60 years of collective experience
- Designed to withstand the rigors of high RPM and high torque race environments
Construction & Design:
The Ironman Unsprung Clutch Kit features a robust construction combining premium materials and precision engineering. The friction disc uses American Sintered Iron, known for its excellent heat resistance and wear characteristics, ensuring long-lasting performance even under extreme stress. The dual clamp load pressure plate provides a heavy-duty clamping force that maintains clutch engagement integrity during aggressive driving and high torque loads.
The unsprung design reduces the overall rotating mass of the clutch assembly, which enhances engine responsiveness and acceleration. This design choice also contributes to the kit’s durability by minimizing stress on the clutch components during rapid engagement and disengagement cycles common in racing scenarios.
Performance & Sound
The clutch engagement is deliberately aggressive, offering a distinct on/off feel preferred by racers for precise control during launches and gear changes. While clutch chatter is minimized, some light engagement noise and gear rattle may be experienced due to the nature of the high-performance materials and design. These characteristics are typical for race-focused clutch kits and do not indicate any defect or malfunction.
Installation & Fitment:
This clutch kit is designed as a direct fit for Subaru BRZ models from 2013 to 2016 equipped with the 2.0L DOHC FA20 engine and rear-wheel-drive configuration. Installation should be performed by a qualified technician familiar with performance clutch systems. No modifications to the transmission or drivetrain are typically required, but proper break-in and adjustment procedures should be followed to ensure optimal performance and longevity.
It is critical to select the correct clutch kit for your vehicle’s power output and intended use. Using an inappropriate clutch can lead to premature failure, transmission damage, and voided warranties. If uncertain, consult Action Clutch directly for expert guidance.
