a XXX-4 Truggy just sold on ebay. You could do a completed listing search and contact the winner or seller and see what all parts were needed. Appeared he put on a XXXT rear suspension package and offset rims for the front. Thats it.
Another option, get an SBV2 pro and make the changes. you can pretty much bolt on everything you need using the RGT4P truck they sell .
Finally, you could also convert a CRT .5, go with offset rims to use truck tires, and get the longer chassis from RC Monster.
