The bumper works perfectly and provides great rear protection. My one request is that you also make a smaller version for all of the Associated 1/8 Buggies Truggies & SCTs that is minimized for club racing. One with the same bottom protections as this one that adds life to the chassis, but that comes up in the rear at almost a 90 degree to protect the rear bulkhead and gear box from getting t-boned on hair-pin turns while racing (small and slim-line profile). Having said that, I love this bumper and modified the hole pattern to fit my RC8T3.1e and its working great.
