Yeah the hub carriers rub the rims. And all four wheels wobble and have ALOT of slop. Its really a poorly desiged car. Any 15 year old like me could sit down with a peice of paper and make it a nice car. Heck, i'd redesign all of the suspension for free if i could.

I'd fix the slop in all the wheels,
put dish rims on it,
a proline ford f-150 body (Like an rc10 bod),
make the a-arms longer,
move the steering servo under the radio plate,
move the gas tank forward to balance out the chassy,
put proline edges on the front,
put proline step pins on the back,
and put a tuned pipe on it.
