The GW backing plates are very hefty.  I’d be concerned about bending.

I reported that I ground a 1/16" off the drum rim and problem solved. Well, not quite, they are quiet when driving straight but rub when making a sharp (90 degree or more) turn.  The rubbing is only on the bottom half of the backing plate, maybe just the bottom 1/3.
