This range of clutch friction plates complement the DRT clutches perfectly and can also be used in other race clutches. They mark themselves out with either 2.5 mm thick friction plates or the amount of friction plates included (4-5). Plain plates are supplied to ensure that the strength of the clutch system does not make it unusable. Even then the outer friction plate and the spacer gasket are usually also necessary.
The DRT plain plates are available in different thicknesses. This enables even more combinational possibilities through experimentation with different friction plate thicknesses. The shorter the clutch action distance, the more direct and powerful the reaction from the clutch. The clutch separation is at its best when the clutch spring action distance is set at a minimum of 1.6 to 1.8 mm.
Conclusion: Now clutches can be set up to suit the exact needs of every motor.
SIP-TIP: Lubricate the friction plates thoroughly and check that the top plain plate of the assembled clutch cluster does not have contact with the outer friction plate. Adjust to fit. Always use a new woodruff key, clutch nut and a hardened clutch cluster circlip.
