We take our bumpers off and bolt them on once per competition for inspection. After that we use reverseable bumpers that many do with Velcro, but this year we sewed in a bungee cord to allow us to flip quickly without having to secure anything.

Our mounting is simply a piece of 20ga aluminum sheet that is bent at 90 degrees and screwed to the bumper with 1/2" wood screws. We then drill holes in the aluminum and run bolts through every 8" or as rules require to attach to our frame. Bolts may not be quick, but we've never had loose bumpers and since we rarely remove them we could care less about speed.
