Im doing the math on upgrading my rally the way id want it and its not going to be cheap. I want to use all traxxas parts. I want aluminum castors and carriers, sway bars, big bores and the centre diff... All this is going to cost about $150 if I buy it new and if I can find decent deals on e-bay. Im thinking it might be better to just buy a slash 4X4 platinum, strip all the platinum parts, replace them with my stock parts and sell it off. I think I could probably do it for less than buying the parts. Anyone have the same thought?
