My brand new kevlar clutch disc judders
You either did not resurface the flywheel correctly or contaminated the disk with fingerprints, oil or grease causing the disc to glaze. Remember flywheels used with kevlar discs must be carefully resurfaced and the clutch must be broken in with easy driving for 500 miles. Any fingerprints or oil must be carefully cleaned off with contact cleaner or brake cleaner before installation. A lightly glazed Kevlar disc can sometimes be restored with light blasting with glass beads.
My metal disc judders
This is normal, metal discs usually have no marcel spring and no hub springs. Live with it or make less power and put in a sprung hub, marcel equipped clutch disc.
My solid hub, all metal, three puck disc clutch judders and jerks real bad
This is normal. A race disc in not streetable. Don’t be a sissy.
Hopefully the information that has been presented in this series has given you enough knowledge to know what sort of clutch will work for you and will enable you to judge how a clutch will work based on its construction and materials. Happy motoring!
