I have the heavy duty pressure plate and modified street disc and love it. Im still on the stock turbo so Im not making much power but it is so much better than the centerforce crap that was in there. It has a very smooth engagement and almost feels like a stock clutch. One bad thing I had was I had to replace the slave cylinder after a couple thousand miles, probably was the original one with 90k miles.
When I was looking for the best price, I found this site and got it from there
