The fp just went around the treads and front wheels. I can try to get something from paint though.
Our build team has some ideas on how to make supports for the bumpers but I don't know them off hand since I'm a programmer.

Yeah... That design idea as some problems.

I think your best bet would be to alter the arms to arch over the bumpers and fit inside the frame perimeter when in starting configuration.
