4.30s all the way if you spray it at the track just run 28inch slicks. i have 4.10s now and if anything happens to them 4.30 are going in. its not that bad you will wish you went 4.10s or 430s after you put them 3.73s in trust me
I have a set of motive 3.90s in my 02 GT and I love them!! I dont have any problems with them and there is no whine at all. I was unsure about which gears to get but I'm glad I went with the 3.90s
