Simple answer, no. It would need a complete overhall, and there just aren't enough aftermarket parts made for it. Even if there were, there would be nothing left of the original vehicle by the time you were done.
Please don't even try....I have a c64-1 because of all the favorable reviews out there.
First mod I had to do was put red electrical tape at the outer most parts of the axle housing to stop them from splitting open. There was more....but if this pic doesn't stop anyone from buying 1 maybe they deserve....a truck that has 2 steering modes, only 1 of which can be used. The sharp angle causes tire rub and strain so the truck shuts down....conveniently that unusable mode is the default at start up and you must remember to change it if you wanna go more than 5 ft before having to restart.
