looks like heaps of fun.. i wonder why do it with such good tyres?? I dont know how relevent it is but after working at a gokart track for two years i learnt 1 thing that if your car is sliding/drifting its just plain slower.. but im sure that does not apply to the donut parts. neal bates and a few other well know drivers used to ocassionaly come to the kart track, hell mark webber even worked there for a little while... but im proud to say that me and the boss beat them all in fastest lap time lol
