[Supras] Clutch and flywheel for track use??

[Walker, Brian (Rich. Dist)]

I'm looking to upgrade my clutch (feels like it's finally slipping, does
fine for auto-x but stops pulling on track around 5k in 3rd and above)
and was going to replace the FW with something to drop weight and
quicken revs. I was looking for a chromoloy FW, found one on Ebay from
CBHaus but I've never heard of them. I also noticed several of the Al.
pieces have a steel face, maybe this would be fine? Jun is listed as
being for the 1Jz.

As far as clutch, I'm looking for something that will engage smoothly
and hold a decent amount of power (the one's advertising 20-30% over
stock don't sound like an upgrade as the stocker holds more than 30%
over stock) It looks like the Carbon disk setups (Exedy, Tilton, TRD)
are only for 1Jz and probably way out of my range. Any opinions on Spec
or Centerforce?
Thanks for any help,
Brian
