Just got the Comp Clutch Flywheel and SBC Clutch. Does the Flywheel come with the correct Step Height for our cars? Or do I need to have it machined?

When I bought my CC flywheel the step was short at .6065 out of the box. I bought it from TMZ Performance & contacted them. At the time they had several flywheels on the shelf & measured theirs & they all measured short too. Contacted CC for help & they said that I would have to pay to get the step remachined. I bought an ACT Streetlite & it measured correctly at .610. I would measure your CC Flywheel & check. My ACT flywheel's quality was very noticeably better than the CC Flywheel I had, measured both. I did my measuring on a CMM & besides the step size measurement I checked flatness & parallelism.

Yeah... the digital calipers i had measured from .600 - .630... I was waiting on getting a better set. But I called CC and they stated I don't need to get it machined and it comes pre-stepped for our cars...

But I'll get it measured again to verify.

Thank you guys!

Caliper is not the right tool. Depth mic is what you need.

You are correct. I was waiting to get my hands on a set today... but figured I would get an estimate with the calipers...
