hi, i was curious what gears i should get for my 2012 gt mustang (automatic 3.15). At the moment the only upgrade is magnaflow competition catbacks. I do plan to supercharge it with a ford racing 624hp supercharger. what gears would yall suggest i get. Oh and this isnt a daily driver so mpg doesnt matter too much. 3.55s? 3.75s? Let me know what you think!
