While you're at it, why not spend a little time working on that suspension? If you're spinning all the way through first then you are giving up a lot of ET. What is your normal 60' time? How much does it vary? If you can get hooked up you can easily pick up a few tenths if you had a crap 60' time like you said in your sig. Go in with some buddies and get a set of slicks mounted on some light rims. You can swap them out at the track in about 5 minutes and see a major difference.
