The Clutch Masters FX850 twin-disc street and race kit for 2005–2007 Audi S4 (B7) 4.2L uses a high-strength billet aluminum cover, twin discs and a steel flywheel to increase clamping force while keeping pedal effort reasonable. The QR Quick Release system improves engagement consistency and reduces clutch noise; options include DLX damped configurations. This kit is intended for use with compatible Clutch Masters flywheels rather than OEM units.
