I have an old Super Athlete that is still running like a champ. Everytime I take it off-road (just playing around, i am not a racer), I end up breaking something. Problem is, I am running very low on parts. So I would like to turn it into a parking lot car. I think I should change the shocks, wheels, and tires, any other recommendations? Where can I find the shocks, wheel/tires? Thanks for any help in advance.
