Here is a fix for SC10 rear rims getting damaged at the axle pin slot. === SC10 STOCK rear rims have a longer slot (where the rear axle pin fits in) than T4/GT2 rims. You can take a rear axle pin AND a SC10 rear rim to your local hardware store or auto parts supply and get some longer one's. IF they don't have some that will fit (length) see if they have some twice as long and make two from one. OR!!!!!! Losi rear axle pins will fit.
