Cool!
Paul: Yeah man... your buggy will drift with PVC tyres! Take a rear and a front wheel off, go into a hardware store, and find some PVC that *just* fits over your rims. Measure the widths of the rims, cut it up, wrap tape around the rim, and wedge the PVC over it. Getting your rubber tyres off might be an issue... from memory yours are glued on? (they're supposed to be)
GTRL: Drifting with PVC tyres on a RWD car is next to impossible, but it'll be fun to watch anyway! I'm leaning towards the netball courts in Curl Curl if there is no track to go on. I'm going to sus out St Ives onroad today!
