Hi there what are your thoughts on going one tooth up on the rear sprocket? I brought a 2011 z that had it already done. Should I change it back? Thanks in advance.

going up one tooth basically just corrects the speedometer reading if you using a 190/55 or 200/55 tire. Otherwise if you're still on a stock 190/50 tire, there it's really a noticeable difference. Now, going up/down 3 teeth is definitely noticeable, but again your speedo reading will be off.
