its always good to have sponge for the racers who are not as good as some of the top lads, if you are a fast enough driver and can pulll out fast times you must be able to be curtious on the throttle ?..
either way i think a small amount of foam is a good idea, the club i race at on a friday night ( SCL model car club ) uses small amounts of foam type stuff u would use on ur old bmx over the handle bar its just right takes the edge of the wall if you crash, but makes it easyier to get away from if you do crash..
