So last night I went to the drag strip and ended up hurting my clutch a bit to the point where it's starting to slip when I hit boost, so I want to upgrade to a stronger clutch but maintain the stock feel of a full face. I have a Fidanza flywheel and stock pressure plate, would I have to upgrade my pressure plate when I change to a stronger clutch or is it just better to do so to have more bite? Main question is what full face clutch should I get?

If you're going to be drag racing more, a steel flywheel is a better option than an AL unit- they stand up to the heat of the launch better and hold more inertial energy for the launch. 'Feramic' clutch material often welds itself to AL flywheel inserts (you can't disengage the clutch when that happens) iirc, Spec makes a steel/chromoly, can't remember.

As for clutch, I had a Spec stage 3+, which is a full-faced unit that was really nice. Only caveat is that the spec pressure plate has straps which can be a liability at times- I'd like to see if the SPEC 3+ disc can be used with a South bend strapless Pressure plate, would be a cool combo.

I don't plan on doing a lot of drag racing this was my first time ever doing it but I would like to go once every blue moon and such it was really fun. Also I want something that can handle more power than I have, so I am looking for a clutch that can handle 400+hp or tq if that is what they rate them by. I remember reading different things about Spec but usually the bad things were from Honda owners not Supra owners.

Personally I never had an issue with the 3+, until I tried to no-lift shift at ~550hp in which case it would slip at ~1/2 clutch life. I have heard horror stories about clutch straps breaking and killing bellhousings, but have yet to see it in person. No idea what influences that kind of failure, though.

Steel flywheel also helps to make the car more street friendly, which is something my car currently lacks :(
