i shredded an RPM front bumper. head-on collision with a pole, and the pole won. a couple big chunks of RPM plastic went flying.
the only metal bumper w/metal supports that seems to make sense is VBS bumpers, ti VBS skids and ti jounces. the jounces act as a spring to absorb impact, and the titanium acts as a spring in itself (to a certain degree of impact. a lot will mess it up, i'm sure). i won't be testing it...
