The clutch hub is stronger than stock and heat treated. Headed rivets are used to both hold the disc together and serve as positive stops for the sprung hub, which spread out the load encountered during hard shifts and launches.

The pressure ring or the part of the pressure plate which rubs on the clutch disc is made of strong heat resistant nodular iron which also happens to have good friction properties. The pressure ring is attached to the cover via dual drive straps which is twice as strong as the stock single straps.
