The clutch takes engine power and transfers it down through the drive shaft into the wheels on the road. It also allows you to disengage the engine whilst performing a gear change. Clutches therefore require a lot of grip to maintain this contact, as well as a very fast response. High performance cars have a lot of power, which means that ordinary clutches often have difficulty operating. If the clutch slips then power is potentially lost. However, power clutches have high friction surfaces and more than one contact plate, meaning they are less likely to slip and lose power.
There are many types of clutches, including race-specific clutches, but these are not recommended for road use in most cases. Road clutches come with a power rating, which means you can tell which are suitable for more powerful and high performance cars. If you use a clutch with a lower power rating you’ll find that it wears out very quickly. More powerful clutches like those made by Panther have more tension between the two plates reducing the risk of slip. These are suitable for more powerful car makes and models, including Volkswagen Golf Mk4 .
