I bought the BMW bash plate and have bent, dented and scratched crap out of it. I replaced the rubber mounts after a bit of log crossing in the snow. 2 rubbers had sheared, one partial shear and one was loose. The front mount was damaged.
BMW wanted about $70 for a set of mounts. I used anti seize on them and use my little battery rattle gun when I fit them. Have done several oil changes and not had issues.
The factory bash plate will move enough to dent the header pipes. It's relative to how hard you hit things. Lift the front over a log and land hard on the bash plate like you'd do on a 250 and you'll break stuff.
