I took my GT to the track for the first time last week. I ran a best of 14.7@94. 60' times between 1.9 and 2.5. Had a difficult time hooking up, was smoking tires. My car has stock 2.73 gears. I would like to be able to run 13's. The car is mint with very strong motor. What do you think I would run 1/4 with 3.55 or 3.73 with drag radials? What rpm is the best to shift ? Thanks
