One thing I would add, if bumpy track is to be used it would need stipulating as cars without suspension are soon off this stuff as it's made for Raid vehicles, it may put some people off.

Actually Ninco "Raid track" for example, is used as a stage in the current "Slot Rally UK" events (as I can testify ), in which some cars even without suspension were run, although not perhaps as smoothly as running cars fitted with suspension.
