Tires!

BFgoodrich comp t/a drag radials. :hail2: . i love mine. Get them nice and hot at the track and they work like magic. The MT e/t drag radials are supposed to be really good as well. They look sweet too.
 
If you have a smaller wheel, such as a turbine, or a weld 15 in wheel, it will consequently lower your gear ratio as compared to using a 16 in pony or anything largeer with the same tread depth. When you go to the track, you should use your smallest wheels with drag radials or slicks. This also gives you more room on a stock wheel well to put higher profile tires. I think Nitto drag radials would be good, I wouldn't put slicks on a stock 130,000 mi. car like mine.
