I Dunno... A bit of glue and some cardboard and it'll be as good as new.
This is a SPEC stage 2 Kevlar faced clutch with aluminium flywheel and is rated to 530ft/lb. Usually a good upgrade for LS1 Commodores running a cam and bolt on mods. A Commodore weighs in at about 600KG more than Phil's Cobra so we reckon there must have been a fault with this one.
Cheers
