One of my friends has a '72 2002 that he wants to setup for racing IT next season. It already has bilstein shocks, h&r springs, poly bushings, volvo four piston brakes in front (is this IT legal?) and it will be rolling on 15" wheels with toyo ra1's (we race with WCMA, so 15" is legal)
Now, WCMA has a catch class called ITGT that is for cars that don't fit IT but aren't fast enough for GT, and we're considering putting a baby6 in the car so it can at least keep up to the IT pack.

What's involved in making a car like this competitive with the other cars that will be running IT?

Thanks!
