I love the difference... I went from 3.08's to 3.73's. The car revs up so much faster now, and I actually have some power in 4th gear. It cost $440 out the door... including speedo gear and synthetic oil. As soon as I started driving it home, it felt as if I had a little bit of nitrous.. haha. It is definitely worth the money. I'm kind of glad I didn't go with 4.10's because I'd go through the gears too fast for everyday street driving. Just thought I'd share that with you guys. Next is pulleys....
