Follow up... The losi wheel balancing kit does not fit traxxas wheels and the frame is too small for MT wheels and tires. So it was a waste of money. Thanks again for every ones help. I wish someone around here knew a little bit more about balancing MT wheels. I don't think I'll be wasting any more money on trying to solve this problem and my wheels wobble so bad that I'm thinking about getting out of the hobby all together. Maybe I'll keep my summit but I think everything else is going to be sold.
