This is no BS. Back in the day when concrete oval was big I was racing a Delta 1/12. I did pretty well with it. One guy commented that "he could win with plywood" then the dares started, oh boy.
I got some 1/4 inch and drew it out over the chassis the bolted the pod on. Raceday came and I felt like an idiot for doing it. 34 entries in that class
I came in 3rd in the A main. I still have the car.
A "LOT" of luck was involved on that one. I guess the others wanted to stay back and wait for the flames.
