Will any single mass flywheel work on the HR specific clutch. Was thinking about the JWT HR kit and buying a single mass flywheel. I'll save abut $300 if I go this route.

 

Don't know what you mean by "any SMF"? You mean like one from any year Z like an '03-06 DE? NO. You said it already... "HR specific clutch". It requires the "HR specific flywheel" (and CSC and master and....)

And if you are going with JWT, why not get their specific flywheel that matches the clutch? Available lightened or near stock weight nodular iron SMF.

 

Z speed is offering this HR clutch kit with a single mass flywheel.
