I want to have the gears changed in my 08 but am unsure of what ratio to go with. The car is a garage queen and I am not coscerned with mileage (even with todays fuel prices). I have read numerous threads and am undecided between 3.73's or 4.10's. The car just driven to events, sunny weekend days, and will see the track maybe twice a year. I am leaning towards going with 4.10's but I have read that the autos don't perform with them as well as they do with the 3.73's. The car is all stock except for an 08 Bullitt intake and a Bama tune. I am not one to fear the gear. My last car an 03 Mach1 had 4.30's and were perfect for that car and mods. This will be the final mod for this car for many years. I would appreciate any input.
