In the last year and a half, I've owned several RDX's. I'm pretty good about grazing the inside corner on the sweeper which sends me head on into the wall at full speed. I can't say that I've broken more than a handful of arms, but I've broken about 10 top bumper plates because there is no flex. Has anyone figured out a solution to this (besides not hitting the wall) or am I the only one supporting someones "Buy a bumper plate and send my kid to college" fund?
