. But it really depends on your goals, I would find someone else with an A4 and the MS4 on this forum and ask them how they like their gears, what 60 ft time then run and what kind of gas mileage they get. Get 4.10s, 3.90s or 3.73 gears-If you have a 2 series rear end (factory 2.73 gears) and do not care about mpg (which you shouldn't with a big stall and cam) then go with 4.10s. Everyone who says 4.10s are to much are the ones with 3.73s. Everyone who says go with 4.10s have 4.10s. I trust the guys running the gear to tell me whether or not its okay. If you have a 3 series carrier (factory 3.23 or 3.42 gear) you can get a happy medium between 3.73s and 4.10s by getting 3.90s (available at Thunder Racing). If for some reason you care about gas mileage, then go ahead and get the 3.73s.
I fill up less than every 200 miles with stock internals...
