Don't waste your time getting gears in an A4, just get a converter and be done with it.

My bad, heres my mods, Hooker LTs, ls6 intake, vig 3200 stall, free mods and 100 dry shot of nos. My best on motor is 12.19@112 and on spray is 11.55@118 with a slipping transmisson which is now fixed. I ask again, what is the diffrence in ET and MPH that someone has seen on going form 3.23's to 3.73's. Thanks.

don't bother swapping gears then, you might drop .15 from the swap.

do 4.10s, those will work out better

4.10's in a stalled a4 that is still on the stock cam....isn't that just a little bit of overkill?

With the converter you have the beauty of the converter slipping to keep you in your powerband betwen shifts....that kind of negates the need for shorter gears.

I just rode in a car that is modded like mine but has 3.73's. He said he picked up about 2 tenths and 2 mph. There wasn't much diffrence in rpm's on the interstate and the car xlr8ed good. The only diffrence that was that noticeable is what speed your car goes into overdrive. I think it dropped about 12mph, oh well, I dont race to many races past 130mph anyway. I'm changing gears.
