best way to learn is on pure ice.... i learned at night in the parking lot of Monarch.
from a parked position:
1) start with wheels turned 1/2 way to locked position to the drivers side.
2) rev her up and feather off the clutch, swinging the rear out and beginning a regular' donut
3)shift into 2nd
3) w/ each rotation increase the turn-in by 1/4 turn of the wheel while shifting to 3rd and increasing throttle (u may have to feather the e-brake to get a pure axis spin going)
4) keep RPMs about 500-1000 under red-line to maintain.
5) to stop let off accelerator till the car slows, while letting off the wheels slowly increasing the diam. of the turn.
(A4's run s 40/60 power bias so the axis will be off by a little bit. 50/50 is best.)
