V-10 Killer

iTrader: (22)

I'm removing my 10 bolt this month and getting my 12 bolt with my tax return check.
I'm still torn between what gear to order with it though.

Here's what I have into and expect from the car:

Currently an A4 (maybe TH400 with GV unit next fall)
I don't trailer the car, and enjoy driving it a lot, so I think 4.11ish gears are out.
I intend to race on either street tires or no taller than 26" slicks, due to the car being lowered.
Will have full BMR/Spohn suspension to compliment it, front and back, with QA1 shocks/springs.
I don't do a lot of weight reduction yet, and if I do, the safety equipment will still bring the car to around 3700lb.
I have a 3200rpm stall converter in it now, but will likely upgrade to ~36-3800 stall nitrous converter.
Car peaks in rwhp at 6600 rpm, peaks in torque at 38-4400 rpm.

What else should I base this decision on?

Thanks everyone.

I would decide about the nitrous if so go with 3:73's IMO.Although if you do a T400 maybe you should rethink the 4:10's not as tall of a fist gear in those tranys. But hey what do I know I am running a 6spd LOL!
