Spec 04-10 BMW 325 2.5L/3.0L E90/E91 Stage 2 Clutch Kit

The SPEC Stage 2 clutch is a premium, heavy-duty clutch upgrade designed for the 2006+ N52 E9X BMW 325i, 328i, and 330i models. It is engineered to handle increased horsepower and aggressive driving conditions where the factory clutch may slip. This kit includes a single carbon-Kevlar clutch disc rated for 485 ft-lbs of torque, a heavy-duty pressure plate, and a heavy-duty throw-out bearing. The kit is compatible with both the stock dual-mass flywheel or a lightweight aluminum single-mass flywheel. It's noted that the stock dual-mass flywheel is a known point of failure due to rubber damper discs that wear out over time, especially with heat and aggressive driving. Replacing the flywheel simultaneously with the clutch is highly recommended to avoid repeat labor. The lightweight aluminum single-mass flywheel option provides quicker acceleration and faster revving but may introduce more "gearbox chatter" or noise compared to the stock dual-mass unit. For daily driving, the stock flywheel might offer a more comfortable experience, while the aluminum option is suited for a more aggressive, sports car feel. SPEC Clutch is a recognized supplier in the tuner market, known for providing superior performance, drivability, and longevity.
