Description
 

ClutchMasters build clutch kits for a broad range of BMW applications in multiple stages to suit your driving needs, from street to devoted track car. Each "Stage" is specifically designed and engineered for specific power outputs, street/track uses, and driving styles and needs. These clutches represent years of R&D work to create a solid clutch kit that's easy on your drivetrain but get the power to the ground effectively.

These kits start out as new Sachs clutches. The kit isn't just a beefed up Sachs unit, the real magic is in the casting of the pressure plate that clamps on the disc. The ClutchMaster's Power Plus pressure plate uses a high leverage design with a ductile iron casting to significantly increase plate load while keeping excessive pedal pressure at a bare minimum. Not only does this feature reduce aggressive pedal pressure that can wear your leg out on the street and track, it reduces the amount of load against the crankshaft reducing thrust bearing wear, throw-out bearing wear, and crank walk. The pressure plate also features a reinforced, FOUR strap design and heavy duty rivets for increased longevity and strength during hard driving. These areas in a stock pressure plate do no last with aggressive street and track driving.

Stage 4 & 4.5 - Sprung Ceramic 6 & 4 Puck System

The Stage 4 uses the Power Plus pressure plate with a custom, extremely durable, ceramic disc for 170% more holding capacity over a stock clutch assembly. This is a great devoted track clutch for drivers who are rulebook limited to stock diameter clutch kit. It is available in a 4 or 6 puck configuration, with the 4-puck being the more aggressive setup. The disc incorporates a solid hub to work in conjunction with the stock dual mass flywheel design for smooth engagement*. This disc is designed for long life, outstanding holding capacity, and rapid heat dissipation. Warning: Due to the solid (no Marcel) friction rivet design, the Stage 4 disc engages quickly (Stage 4.5 engages even harder) and can cause increased wear on the drivetrain with abusive use. It also may chatter slightly in first and reverse. To help alleviate this problem, ClutchMaster only uses premium ceramic friction material. This kit also works well for devoted track cars that do not have the ability for an extended break in period. Ceramic breaks in easy, especially compared to Kevlar.

Kits include throw-out bearing, clutch disc, pressure plate.

If a ClutchMaster clutch kit is planned to be installed in conjunction with a used flywheel the flywheel MUST be professionally resurfaced beforehand. Failure to resurface a used flywheel will void warranty. Please contact us for further information concerning flywheel resurfacing.

Applications having a stock single mass flywheel will have a sprung hub disc. If your car came stock with a dual mass flywheel but you plan to use an aftermarket single mass unit, please contact us if you plan to use a sprung hub disc. We also carries aluminum single mass flywheel / sprung hub clutch kit combos.

E30 318 (M42) will need a different starter, flywheel, and throw out bearing. Call for assistance.
