440 Source Flywheel

Wondering......Does that Kevlar disc require a flywheel with a special face or insert?

Very possible, but what intrigued me was the fact the PP was like brand new, not a scratch. Those clutches didn't spec a special flywheel from what I have seen. The flywheel was toast, just a fair warning. Hope everyone elses experience is better. I am running RXT disc's this time.
