The Action Clutch Stage 1 (1OS) clutch kit with lightened flywheel for the 2003 BMW Z4 2.5L DOHC RWD is built for stock to lightly modified cars. It uses a reinforced steel-backed copper-Kevlar organic friction disc and a single diaphragm heavy-duty pressure plate to preserve an OEM-like pedal feel while increasing holding capacity by about 70%. The kit includes fully enclosed spring retainers for added safety and is recommended for heavy-duty street use and mild track duty.
