What is the top end of a 03 GT with 3.73 gears as the only mod? My buddy has just changed the gears in his 03 and was wondering if he hurt his top end or improved it. Has anybody ran a GT with these gears that fast? I was thinking that the 3.73 would help him out because he would be able to whined 5th higher and get more power. What do you guys think?
