Crush Cans
I went ahead and added them to my ARB install. Didn't take long to do and I have the peace of mind that I did the intall per the instructions.
The bumper caps aren't fiberglass... at least mine are not. Just a tough injection molded plastic. But you can bet that if you ever did tap something without those crush cans it would mush those 'bumperettes' down to the metal. The cans may or may not help, but mine are there and that's enough for me.
I guess it just comes down to if you want to take the time and effort to do it... it can't hurt anything to leave 'em in that's for sure.

Good Points.
I am not 100% sure they are fiberglass (looks like it) but when I thunked them against my desk they sure sounded solid.
