what is the stock diff ratio in the 07 mustang gt and also if u buy a 9 inch rear end what better 3.73 or 4.10[/img]

cams-shelbycobra07 · October 7th, 2007, 11:23 PM

Just wondering, but y buy a 9 inch rear end? y not just build up the one you have?

ujslost · October 8th, 2007, 07:19 PM

it would be a hell of alot cheaper.
If ya give me your vin I might can tell you what gears you have. Im guessin 3.31s

06RedfireGT · October 8th, 2007, 09:56 PM

If it is an 07 it has 3.31, and the 8.8 thats in there is pretty tough. It will take a hell of a lot more than the stock motor. I woulnd't worry about it.

yea the 3.55's are an opt

gtcs mustang 13 · October 14th, 2007, 11:00 PM

ok since i got the 3.31 if i where to put 4.10 what would that do and what should i accept

MustangMatt96GT · October 14th, 2007, 11:19 PM

make it a whole new car! Much better acceleration, and the seat of the Pants Dyno will show like plus 50 horsepower!

4.10s FTW

06RedfireGT · October 15th, 2007, 10:14 AM

Yes the 4.10s will make a massive difference.

gtcs mustang 13 · October 16th, 2007, 02:44 PM

If installed properly by a good professional that you trust, then you shouldn't have any problems at all.

gtcs mustang 13 · November 20th, 2007, 03:59 PM

lil red · November 20th, 2007, 04:51 PM

go with a 3.78. trust me. we tested it and its the best all around way to go on the new gt's

you mean 3.73's?

gtcs mustang 13 · November 20th, 2007, 05:57 PM

ok so 3.73 will give me good accel and good top end

leebunnyz · November 20th, 2007, 07:52 PM

if your staying n/a i would go with 4.10's. if your eventually going F/I i would go with 3.73's.

gtcs mustang 13 · November 20th, 2007, 08:52 PM

what is the difference in 4.10s and 3.73
in accel and top end

leebunnyz · November 20th, 2007, 09:30 PM
