I have a 2002 GT M5 and I may be wrong but if I remember right it has the tremec 3650. It's late and I'm tired, so I may be way off. I think that they changed the transmission in 2002 or 2001. Not sure which though. Going from 3.25 to 3.55 won't be much of a difference for the amount of money your paying, I'm going to slap some 3.73's in soon on mine. 4.10 is too extreme and 3.55 isn't enough, I like it right in the middle. Just a thought. You also might want to look into the STeeda Tri Ax shifter if oyu haven't already, I think it has a little more comfortable position.
