a4 launch ok so i have an 02 cam z28 and its auto 
.... if you hold the brake and rev it to about 3000 rpm then at go leter rip does it give you a better launch then just punching it? i raced another cam 02 z yesterday while using the brake method and had about 1 1/2 cars from the launch...i have k@n cia, slp cat backs and speed chip so it might not have been the launch but the mods....anyway does anyone really know which technique will give you a better launch

Factory stall speed is around 1,600 RPM. You will have to play with different RPMs to find the best launch technique for your car/tires.
An auto isn't like a 6 speed. You can't just choose what rpm to launch at, you've got to buy a converter for that. You will easily find out what rpm your car will hold, and if it's not good enough, buy yourself a stall!

I think he is asking opinions on which way launches better.....brake stall it and then launch, or just nail it out of the hole. IMO, one foot on the brake and the other foot giving enough gas to tighten everything up but not spin the tires is the best way. Might be different on cars with a higher than stock stall though, I dont know. Ron

His post is a joke
DON'T do that. Footbrake is the best way.

I've always wondered what would happen if you would accidently put the car in reverse while you are crusing on the highway. Just wondered, would never do it.
I believe tires play a part in this too, with my old car when I tried to foot brake it I would spin all day, but when I was able to just feather it from the start and get traction I did much better. But with my new Z I'm able to launch at higher RPM's and still maintain traction pretty well, and get better launches compared to feathering it until I can get traction, but I have nice tires on this car.. Obviously the best thing you can do for an A4 is a stall, but if you don't have the money... like Me... just use whatever you think works best.
