Bekkers lists the following in their catalog:

Bekkers Imports offers a full line of stock, sport and racing clutches from Fichtel & Sachs, the OEM for both BMW and Mercedes. The sport and racing clutches are sold as individual components. Sachs sport and racing clutches are made for applications where the clutch is subject to above-average wear, such as: modified engine output, turbo-charging, autocross & track driving, racing or frequent trailer towing. In most cases, a pressure plate with increased clamping force, combined with a sport clutch disc will stand up to excessive forces. The lightweight pressure plate is made for racing, where reduced rotating mass is desireable. This allows quicker acceleration and deceleration of the engine.
