A4...Gears?

What gears are you guys running with your A4's? I just put a shift kit in mine and it made a big difference in the 1-2, and the 2-3. Not much of a difference in the 3-4 though. I have the 2.73 rear gears now and want something for the strip but also need to drive it on the free way. I have read a lot of post about rpm ranges and the difference between the 3.73 and the 4.10 is only about 200 rpm at 60-70mph. Let me know what you guys are using and if you like it, or what you would do different.

I went with 3.73's it seems to be the populat gear to go with. I think 4.10's would be a bit too much for the amount of hiway driving I do.

3:42'S make the perfect gear for highway and the track and going from 2:73's you will notice a big difference.

3.73 all the way..@ 75mph my rpm's sit around 2500-2600. Noticed a slight diff in gas milage but real minor. If you drive a ton of hwy go with 3.42. Anythings better then the 2.73..

3.73. Great gear for A4 26" tire. If you start getting enough power where it becomes a problem, throw a 28" tire on.

I am running 323's... not much "if any" difference in the 342's... I am also running a 3600 stall, car runs VERY good, high 11's in the 1/4.. and still get 20-21 mpg hwy @ 280-300 miles to a tank of fuel... Not too shabby if you ask me...
