Question SPEC clutch install help...

Need some installation instructions (ASAP):

what is torque spec for pressure plate to flywheel screws? flywheel to crankshaft screws?
safe to reuse old fasteners?
what is the break-in procedure? i am upgrading to a Stage 3 carbon disc...


thanks!

Flywheel/flexplate bolts...74 ft-lbs
PP bolts.....22 ft-lbs

Reuse the bolts if they are in good condition.

Break in...... take it easy the first 400 miles.....this is pre SPEC

I've been told it's good to put anti-sieze on the bell-block bolts as well.

I read somewhere that you shouldn't re-use the bolts if they've been torqued down more than 2 times...cheaper insurance to just get some new ones. I'm sure they'll be fine, and I forgot where I read that.
