Hi Everyone and thanks for the tips. I used buffing wheels with red compound and it worked great.
These are 18" Turbo Twist wheels from a Porsche 993. I found them at a junk yard and nabbed them (with conti sports) for $500. What I like about them is that this gives me the same circumference as the original stock wheels/tires so I didn't have to re-gear the differential to get everything dialed in. With the 3.0 SC engine, there's plenty of power for these. The car handles great and looks cool too.
Thanks again!
Daniel
