I've worked on the rear bumper. I am using a Slash 4x4 bumper, borrowed some ideas I saw on other forums. It's pretty easy really and I don't think it looks to rigged. Although my dremeling of plastic skills suck.
I plan on using the wing mount as the body mount/rear bumper tie in. Looks ok so far.
I ordered a RPM front bumper for the Slash 4x4, I also emailed T Bone Racing about making a front bumper like their Hyper 10 SC,
