Black_03GT

Well im going to buy some gears tomarrow. Im curious, 3.73s or 4.10s?

im kina thinking 4.10s but i was wondering the differences in gas milege, how much faster, .etc in both of them over the stock gears.

Also, how much is my speedo going to be off before i can get a tuner to fix it?

Go at least 4.10`s or nothing. Loss of gas mileage might be 1-2 mpg. IMO, you should get the tuner and gears at the same time. www.mustangtuning.com and www.rpmoutlet.com have gear/tuner package deals.

4.10s for sure.

if you drive easy which will be hard too. your fuel mileage will b minimal. but remember what code always says "dont fear the gear" i love my 4.30s
