The Clutch Masters FX850 twin-disc race kit for 2005–2007 Audi S4 (B7) 4.2L pairs twin discs with a billet or steel flywheel and a high-strength billet aluminum cover. Machined covers reduce flex for consistent engagement, and the QR Quick Release system helps even engagement and quieter operation. Note: this conversion kit will not work with an OEM flywheel and is built to be used with Clutch Masters-specific flywheels.
