This track was made to prove/disprove a theory. Can a car produce enough downforce to drive upside down. Turns out, no, it cant, as far as I can tell. Play with it. It has just he basics, no lights, no nice textures, just enough to get it running in game. Its basically a very long tube with a road around it. The Max8 file is included so you can modify it or do whatever you like. The tube maping sucks but then again, it all sucks. Its just to see if a car can drive upside down. MUST USE IT WITH THE AIW EDITOR, IT HAS NO AIW FILE so it wont open in normal rF.
