The large universal rokblokz work well for the purpose you describe. I got some brand new OEM mudlflap body mount plastic threadsert thingys, new screw bolt dealios, punched holes in the rokblokz, mounted them in the rear only, and have over a year with at least 400 speed bumps, 150 curbs, and one tree rat with zero issues. They are rediculously expensive and favorites for overlanding, aka trustafarians, plus rally, which can be nerded out on.
If I actually went off road I could remove them easily but all I'm doing is real life grown up legos and model building. They look great without being noticable and protect the labs void. Pretty sure there's no junkies or bums in the bumper back there but really who am I to judge. No pics deal with it.
