I have a jdm Ep3 primarily for track (not concerned with high revs or fuel consumption). On the track I drive on, 4th gear is the highest gear I get to, and the race starts as a rolling start so don't have a first gear move off situation. Everyone in my circles is advising to go 6.33 final drive to maximize acceleration -sounds like it makes perfect sense to me -it's just that when I research I don't see anyone really using the 6.33. Anyone have any experience with or thoughts on this?
