[QUOTE="Driver72, post: 9786511, member: 105832"] When the 11 GT came out a guy on another forum put together the numbers and made up a downloadable "gear chart" for all. I ran the numbers too but you should edit and do like I did and post with 27.2 inch tire as that's what the OEM 18 and Brembo 19 are. Or if I can find it again, I could just post a link to the "gear chart" this other guy did several months ago for all to download here too. As I've continued to say, the 3.55 ratio to me would be the best choice for dragging, especially when stock or with bolt ons and tune, and maybe even more so with a supercharger as the 3.73's will just equal more wheel spin unless you run slicks. 3.55's will do about 119 mph in 4th (at 6850 redline) (or a bit over 120 if you run to the fuel cutoff) which is perfect for traps in the 117-118 mph range (where you could be with bolt ons and tune). The 3.73's require a shift to 5th on a fast track (even on a stock car) which just kills the run where you shift right in that last 66 feet of the trap speed lights. With light mods you need to shift to 5th well before the stripe and with a 3.55 car you still stay in 4th saving the shift time and loss of acceleration and taller gear ratio 5th bring compared to 4th (meaning you will accelerate faster in 4th with 3.55's than you will in 5th with 3.73's) [/QUOTE]
