I'm thinking of getting a 13 or 14 automatic GT and adding 3:73 or 4:10 rear. Since it's to be a daily driver don't want to be too far out. Any thoughts ?
Opt for the 3.73 gear man, I just had mine done and it is great. First gear is very tall in these new Mustang's so 4.10's are too much unless you are doing quite a bit of drag racing. I have driven both and that would be my honest opinion.
