I would get the stock EXT2 parts and wheels that were "taken out".
Parts List: Duratrax Evader EXT2 EP RTR
I'm pretty sure the EXT2 plastics are Duratrax's MagnaFlex material. Which is a good thing for "bashing". They aren't as hard/stiff as the original Evader ST material (which most of will fit the EXT2).
The EXT2 stock six split spoke wheels hold up fine under normal power (so I'm told). The Evader ST wheels will also work, but I don't really recommend the rear Evader ST wheels. Depending on how much power you got going through the RC will determine the longevity of the rear wheels. Wheels for the Losi XXXT will also work and have the about the same offset as original Duratrax wheels. Associated RC10T4 wheels will also work. The only thing with the T4 front wheels is the offset. You will widen the front end a bit using them.
