Getting 3.73 gears put in the GT500 tomorrow night and I hope it gives me the help that Mark thinks it will. It shouldn't be much less in second gear than the 3.55 gear was, as the guys with the 3.73 gear say they are about 82-84 mph top speed in second gear at 7400 rpm's. That with the lighter rotors all the way around and the new front stiffer springs should let it turn in a little bit more crisper. Time to find out will be Sunday, every thing should be on except maybe the front springs as they may not get here in time for this Sunday's event but will be on the car for the smokies event.
