Here's what I do.
redvette77 told me to use an SL65 AMG Roadster, and it is a magnificent car to drift in.
Stay in 3rd gear manual, while your trigger finger halfway pressed. Aids off.
As the turn approaches, floor it, tap the joystick once to either direction the turn is and your car will turn to the direction.
As soon as you floor it counter steer and hold the counter steer thru the turn then after the turn release the gas and brake.
If you want to drift thru long turns, do the proccess, then as you begin to slide out, release the counter steer and gas for one second, then gas and counter steer at the same time again.
If you counter steer early you will slide out, if you floor it early you will slide out.
You will need practice, best in the raceway. :) Happy drifting! :)
If you want someone to drift with, send a message to forerunnerD. :)
