^ forget the rules, written or unwritten - do NOT run without metal bumpers of some type. You are asking to bend frame rails with even a minor bump, and do much more damage to quarters, and in the front, radiators.

If you want to lose some weight then just swiss cheese the factory bumper bars. Otherwise fab up some mild steel bars and extend the ends to curve around for better corner protection.

I'll be close to making weight without removing, but was curious since the photos I've been looking at show many cars without. I am considering making a steel rear bumper but doubt that it would be any lighter, although I may try just because I hate the look of the rear bumper with the license plate area removed.

Weight without me, cool suit, or fire suppression system and 1/4 tank of gas is right around 2450.

I'm now at a point where I'm asking the same questions. If the front bumper is supposed to be legal to change/remove I'd probably opt to cut it up / swiss cheese it to save weight but not eliminate it. Right now I plan to leave it as is - to me that change appears illegal by the written 2017 rules. I'd be happy to hear otherwise.

I'll probably do something with the rear bumper though. My reading of the rules is one can remove and optionally replace it, so modifying or swiss cheesing the rear bumper seems fine and legal.
