This clutch disk is made by the original supplier to BMW SACHS. It is identical to the original BMW part.
Important Note: When replacing your clutch, it's not enough to just replace the disk! It is imperative that you also replace the pressure plates and the diaphragm spring.
it's also important that your clutch cable is properly adjusted. This is important so that the clutch actuation mechanism has full movement. Failure to perform these tasks may result in premature failure, wasted effort and money.
