Thanks guys!
BLboy: I would lower it, but trust me, I need every mm of that height. The suspension articulates quite a bit. When the chassis bottoms out, the tires still rub on the body.
magman: I just replaced the stock buggy bumper with a piece of 1/8" thick aluminum, bent at the right angle. The two screws are just there to hold it for now. I will be using 4 black hex screws with the proper locknuts. There is also a top plate that attaches to the flexing part of the bumper too to give it some strength.
