    My brother put 4.10's in his A4 - too much IMO. Have you considered a stall?

    4.10's too much? Say it ain't so batman. I love mine. The tires hate it but I love it. I'd do it again in a heartbeat 4.10's all the way. 4.10's + a stall produces ear to ear grins just about everytime. Buuuuuut that is if you plan on upping the rev's some time in the future. 4.10's in an a4 with the stock rpm ranges on standard tires will make you shift into OD before you cross the traps in the quarter which is rough on the venerable 4L60E.
