I use to race go carts a few years back but not on the black stuff I joined Dirt Trackers Cart Club, the track was made from the old speedway surface from Claremont Speedway (W.A) Had a KT100 cart cost me $1800 and to race a session all up about $1000 to $1200. Thats how you learn to throttle steer, no better action than the lack of traction Ohhh an the wave of mud when you start rear of field when on P's
