I have a Jun flywheel and the no the JUN doesn't have to be resurfaced. You can resurface it if you need to though. You can't resurface an aluminum flywheel.

 

that's what i was sayin: it can b. which i think would b more optimal. it would b a pain in the *** to get a new face, when the time comes. with the jun, u buy it, and your set.

 

yes the JUN can be resurfaced; with JWT, you simply replace the friction material. There are plusses to some with one design vs the other.

From personal experience, we always use a 1 piece billet piece whenever offered for street car use. An aluminum flywheel by its nature is made up of components that are bolted together...of course the inherent risk is if the bolts back out....whcih could be a nightmare no matter how you look at it. A 1 piece flywheel obviously does not suffer from this.

As for resurfacing, or replacing the friction material, its pretty much a toss up honestly.....6 of one, half dozen of another....one is neither better nor worse in this regard.

 

I'm waiting for the EXEDY single plate clutch/flywheel combo.
Exedy is great. The flywheel is chromoly and the clutch is sprung and will hold 400hp easily.
