We have an aluminum frame on the inside of our bumpers made out of 2" by 1" by 1/8" aluminum angle. This sits on top of our bumper mounts and has holes for threaded rods where we put the wingnuts that hold the bumpers on. When we get hit hard, particularly in the front where the bumpers have less support, our bumpers will flex inward. The plywood springs back but the aluminum frame stays bent.

If the plywood became bent I'd be worried.
