    Moser 9", should I get 3.73 or 4.10

    I am ordering my Moser 9" for my Trans Am next month. It is an A4, not a DD and Im 430hp at the rear wheels. I am running 26" tires and the car see's mostly the track. Should I get 3.73 gears or 4.10 gears? I would also like to add a 150 shot of wet nitrous in the future.

    I'd go with 3.73's for an A4.... at the most 3.90's.... just my .02

    Hopefully Nitrous by summer. Do you not think 4.11 is to low for an A4? I was worried about my speed at the trap.

    3.90's IMO.

    Pretty sure that youll run out of motor with N2O and 4.11. Mines an M6 with 150 shot and my shift light comes on as i go through the traps @ 122-123mph. My gears are F**ked up and i need new ones (moser 12 bolt). I know if i go with 4.11 it will require a shift to fith gear in the 1/4.
