Tires are the biggest factor. long time ago, but read a magazine article (Grassroots Motorsports?) comparing a bone stock car vs a competive AutoX car. Of the 5 sec in difference, about 4.5 was the gummy tires.
That being said, I'm headed to the street tire class. 1 kid in college, and another coming up. Doing the financial math sucks.
