thats fine, butif you want proof or your own ideas, you need to see how it acts when taking corners. if you have a video camera or a friend with one. set it on the ground on the racing surface and corner hard; right in front of it. as in, put it on th outside edge of a corner. that way you can see why is spins. with the rusty it is because it becomes way too offbalanced. my towers fixed it.
