With a good clutch there's no need for the flywheel to get warped to the point of needing machining on any sort of regular basis.

I loved my Southbend/act streetlite combo, very nice streetable combo. I put a good 40k miles on it and a well over a hundred passes down the track.

It's advised not to mix the SB disks and ACT pressure plates as with some revisions there are release issues and as of the last couple years, ACT PP's seem to like loosing fingers.

Extreme PSI is a very good company to deal with, I've spent a few grand with them with zero issues. But as you know the exchange is killer right now.

Ziggy at RTM will take care of you very well.
