A performance clutch is designed to provide improved clamping force and/or an alternative friction material to increase the torque capacity of the clutch. This allows the clutch to handle increased engine performance without slipping or failing.

Like with most performance modifications, performance clutch kits come with a compromise. Each clutch is different depending on the level of performance. Some can have slightly increased operating effort and levels of shudder depending on the diaphragm and friction material.

A performance clutch can also cause increased noise in the driveline and twin plate kits can “rattle” when the clutch pedal is depressed due to the floating intermediate plate.

These side effects are generally very minor and are often overlooked due to the benefits of a performance clutch upgrade. If you need help choosing the right clutch for your application get in touch with the PBMS Team here.
