Restrictors...smaller tire idea (already mentioned)...&/or mandated PSI minimums; are all simple low cost solutions not too many like to recognize...if the series has wings, what about standing them up at a certain fixed angle so they slow straightway speed??? Higher weight rules (NOT so that we are bolting on LBS of led, but maybe just not skimping in certain areas...thicker panels in lower the "cockpit" area, etc...)...nerf bar/bumper thickness/size rules...etc...
