Have you ever tried that method before. Because my team tried that and 2012 and it was extremely difficult to slide it over the superstructure on the robot (of course you don't have any superstructure, but your robot next year probably will). Instead, we ended up having it come up from beneath the robot. (Yes, you have to lift the robot to do this. It takes us a long time to change bumpers). However, it is very difficult to do this with 4in wheels because of the minimum bumper height. The benefit to it is that a single piece bumper adds a ton of rigidity to the chassis (this year we were literally able to get away with a plywood board as a chassis and use the bumpers to reinforce it).
