IDK if this adds to the discussion at all, but back in ’01 we only had sidepods, no nose cone and the rear bumper didnt cover the rear tires. One race we had a rookie join us,on the 2nd heat I pass the finish line and slow because the race is over, his front tires touch my rear tires and his kart launches up onto mine and basically lands on my head and shoulder and was stuck there. The last heat were going into the last turn and he brakes way too soon, and my front tires touch his rears, my kart launches like 8 feet in the air and cartwheels away, while i land on the track, and that was the end of my first go kart.
