I am set on getting 3.73s in my A4 T/A and want to see what you guys run in yours or suggest ? I have been looking at the Richmond 3.73s. Overall I want no wine so I dont mind spending the extra money for that. Also would you guys recomend getting an instalitoin kit as well, like new barrings, seals etc. I will be buying them next weekend so I can break them in before I go to the track which is in a month from today, let me know what you all think, thanks.
