Just bought My 02 TA a4 has 3800 stall 4:10 gear. The car puts down 420whp. Looking for the best power from 40- to 140.. Is 3.42 best for the a4 ? I ran a m6 ss the other day from a 40 roll sitting at about 4000 rpms on take off so only in 2end gear for a sec pulled the car a good two car lengths through drive but when I went into od at just over 100 the m6 ss started to reel me in... Wat is the best gear for this type of race against a m6 car with 3.42 gear and basically all the same mods. Thx in advance for any advise.

I personally like a 3.73 in an A4 for a dd street strip. Also I wouldn't recommend going WOT into OD.

3.42s-3.73s are a good all around gear

Thx have 3.42 ready to go in.. Am I going to be week on bottom.. I feel like this thing has tons of power an the 4.10 is robing a lot of the cars1st and 2end potential outside the 1/8 drag strip?? I had a lightly moded 2000 z and it was very strong from 30-40- or even just under 70 it wld kick down and run pretty nice..? Not sure if that car had 3.55 or 3,42? I was dead even with a ws6 m6 car with couple more mods .from 70 and slowly started Walkn @ 130
