both, they look cool. However... to drift with control and skill, you need a TON of grip, like; a lot of pro spec cars won't be set up all that differently to a circuit racing car. Maximum grip means maximum speed, angle and control. It's why there's drift specific tyres which are uber soft, to allow for all the grip that's needed
Forget the carpark heroes, for drifting on track you want no camber on the rear, loads on the front and grippy sticky tyres all round
Edit, funnily enough, I think I'm actually suffering from a mistake. I've taken TOO MUCH weight out from the rear, so the car is prone to spinning out really easily. Slippery back end is slow and unpredictable, grippy back end is fast and predictable
