I have a 00 t/a, and i plan on upgradeing to a Dana 60, i have an A4 and i would like to know what kind of ratio i should be looking at for the rear end if i plan on driving it on the track on some weekends and using on the street. I have seen others with A4s and built up rear ends, and at 65mph their motor is going 2000 RPM, i think thats alot of abuse on a motor when i will be doing 75-82mph on the hwy. and i might be doing that every day. Any ideas?

i have a stock 10 bolt with 3.73's doing around 75-80 when i drive it everyday on the interstate its right around 2600-3000 rpm's...if 2200rpms concern you i wouldnt get anything higher than 3.42's....my gears are great for acceleration...but lack with top speed....hope that helps out some

I DD my 9'' with 4.11's, and on the highway @ 70 MPH I am at 3000rpms. which is not bad at all considering that I drive a non lock up 4400 converter.

Lowest gear for S60 is a 3.56. I always recommend 3.73 gear with a A4. 78 mph with 3.73's and 26" tall tire is about 2700rpm.

I dailly drive my ss 30-miles each day which is mostly highway. I have moser 4.10's in my A4, my topend is still extremely strong. I don't understand why people think getting higher ratio gears kills your topend. I did have my computer tuned adn rev limiter increased. But everyones opinion is different.

I know the power would be more at a slower speed, but what about ware and tare on the motor, car the motor hold 3000 rpm at 77mph, and last a normal "engine life"? Or does the redline matter where it is? Like 6000 rpm to lets say 7000-7250 rpm.
