well a year or two back, i had only been racing a few months and after i replaced my yokomo cutom car with a pro4 i really struggled to get round the track without one little scrap of the bucky wooder board that my club use as markings
so my dad made me these parts which really did help with the 'chrash testing' lol
it really does work if you want to try and make some
but if not the best thing you can do is slow down, dont rush and gradually speed up, there will come a point where you wont ever feel like chrashing... obviously it will still happen thou
i did have to replace the car with a new one though when i decided it was time to take them off because they had increased the wear rates dramatically... just think, if something doesnt brake in a chrash, it means something else has taken a big impact, and become slighty imperfect...
