We generally use a 1x1 square tube (with radiused edges) to rim the chassis and provide bumper support. The kit channel nests very nicely over the square tube. We fab/weld support clips from 2 short pieces of the kit channel and use a quick release pin at each mounting point. Making the bumpers in L-shaped sections will make them even more secure when mounted. See a model in this thread:

Having said all this, post #11 clearly takes the cake, and we'll definitely look into this approach this coming year.
