i usally do 4500-5k launches. and al i do is, once im ready to launch i let off the clutch alittle until i feel or see the car move and not bump but quckly but smoothly let off the gas....
back when i had my stock tires, i would spin my front tires alittle.. haven't launched it with my new ones.... but thats how you launch it on an Impreza... a MaszdaSpeed 6... not sure...
do yall have transfer cases..? if so ask some Evo drivers. but im sure Phil already helped you out on that.
