Is the reason you couldnt bring it to earlier rounds cos you had to find a new one after converting the other one into a nascar cerb ( i.e it would only turn left of go straight on)
Cheapest race car conversion I ever did............actually made a profit on it
Didn't go very well though mainly cos it only had 3 wheels. Tried this on the Taz during early pre-season testing but it didn't work on that either!!!!
