everyone will say 410's...I went 373's...both of these are teeny little gearsets...if you don't hook you should be fine with either....the higher numerically you go, the more teeth, the smaller they get....in the case of our stock rears, that is pretty damn small.

well if you plan on going with the 3.73's ive got a set for a 3 series carrier. bran new never installed i ordered the wrong gear set i ordered 3.73 for 3 series when i was suppose to get for 2 series, so now this is just laying around. The brand is whatever slp sells that where i bought it. might be steep but ill do $200 shipped. pm me if interested but please make sure its a 3 series.

i suggest 3.89 or 4.10s,but i would suggest a 9 inch or 12 bolt also since it looks like you have a pretty healthy motor.

Def 4.10's outta those two. I am thinking i am going to get 4.30's. Seriously who needs to go 200mph? I am sure with 4.10's your rpm on the interstate is still below or at 2500!

Verify that please...

We have 2 overdrives so to speak misewell take advantage of that.
its like having a 4 speed with 2.15 gears...plenty

with a 6spd and 4.10 you should be right at 1900-2000 RPM at 70.

I've heard that the jump from 3.42 to to 3.73 almost isn't worth the cost.

4.10's... but I'd be easy on them unless you get a stronger rear end. That 6 speed isn't going to be as nice on the rear end as an A4 would be.
