Compatible with a stock flywheel or Dinan Stage 1 Lightweight Flywheel. This application requires machining to the stock flywheel for clearance (Lightweight Flywheels purchased after October 2011 will not require machining). Highly recommend for use with Dinan Lightweight Flywheel. The kit does NOT include release/throwout bearing or installation hardware. Dinan recommends replacing the release/throwout bearing, clutch fork, and slave cylinder when performing a clutch replacement. BMW OEM parts are compatible and recommended with the clutch kit.
