Billet Series Clutch Kit

The Ringer Racing Billet Series Clutch Kit is a premium clutch system engineered for the B7 S4 4.2, built by Clutch Masters exclusively for Ringer Racing. This kit features a heavy-duty billet aluminum pressure plate cover paired with a choice of 850 diaphragms. These diaphragms offer 7-14% more clamp load and holding power than standard Ringer Racing 240mm clutches, establishing it as one of the highest-holding single-disk street clutch kits on the market. The kit includes the Ringer Racing 240mm Billet Series Clutch, a throw-out bearing, and an alignment tool. Buyers can select from various stages, each offering different performance characteristics and material compositions. Options range from Stage 2 (Daily Street Clutch with organic material) to Stage 4+ (Street/Race Clutch with full-face cerametalic material). The stages also differ in diaphragm color (Blue or White), with White diaphragms indicating increased clamp load and pedal resistance. Torque ratings vary by stage, with the Stage 2 clutch holding up to 600 ft-lbs at the flywheel, and the Stage 4+ clutch rated for an impressive 1125 ft-lbs. For installation, the supplied pressure plate bolts require 25 ft-lbs of torque with a dab of Loctite. Ground shipping within the 48 states is included, with options for expedited shipping.
