My friend has a 2.73 gear A4. He wants to know if he should go to a 3.73 or a 3.42. He dont want to shift out of drive in the 1/4. Will the 3.73 allow him to make it all the way thru the 1/4 without shifting out of drive? I have a 3.73 in my car but i havent ran it in the 1/4 yet, still breaking in the motor.
