I know back when the bullhead came out I actually bought one of them instead of a clod. Since I was not going to use the semi body( or Clod for that matter) The Bullhead had better motors and also had metal chassis supports where the links for the axles mounted so you would not pull the ball studs through the plastic. the Bullheads withthe Johnsons were a bit faster than the mabuchis( spelling?) in the clods at the time. I was going to use the bigfoot Parma body anyway. I just painted the chassis black,
BTW did the latest Super Clod had the metal chassis bracing??( this pretty much got rid of the need for the likes of the ESP chassis brace)
