get the 3.31s, save the $100, go on americanmuscle.com, purchase 4.30s, have local stang club refer you to installer, have them installed

I recently had an auto v6 with 4.10s and man i burned through gears what seemed to be pretty quick. is there really that much of an advantage to having the 4.3's? is first gear gone in an instant or what? i just want a little more info so i know what i get is what i truley want. thx man

4.30s are about 2 mph less then 4.10s, and you can start off in second for DD, the t3650 in the GTs is also a .62 5th gear, where as autos are .75, so with 4.30s in a GT you will still be under 3000 rpms at 80 with stock rubber

@sycd: yeah, I guess. when I check out the other preformance packages, it also states 2006, but they specify that some items can't be used on 07 models.
anyway, it will be installed trough the dealer, so it's up to them to tell me if it's not working, I'll have it dyno'ed just to be sure....
