I miss the function - it was possible in GT5 prologue. Pull both gear shift paddles for neutral. Could properly clutch kick the car into a drift from any revs.
I have been trying to find a way to do this and the only way i have found is a wheel with a H-pattern shifter and clutch pedal. Cant find neutral on controller or with a wheel with only paddles (even if it has a 3pedal setup)!
