I think youll be pleasently surprised when you take it to a well prepped track the first time, it should be so sticky that itll take your shoes off your feet if you try walking down the first 20' of the race track. Hell, I could spin em in my fiero on the street for a month (not racing) before I took it to the track and blew up my tranny launching at 2k rpm. Good Luck! tell us how you do!
if thats not good enough... relocate the battery, ladder bars or 4-link, stickier tires, 90/10 shocks in front, any weight reduction that you can do, etc.
