The rear bumper extensions have been rigged up and tested for "dither" on an exptl. Wraith. The test results were very satisfactory, there is no period set up by the bumper, and only a very slight "dither" over rough roads. The brackets are strong enough to withstand anyone standing on the bumper, and in our opinion will not require any additional support from the body.
