I advise against the backing plate eliminators.i did that to mine and the damn brakes squeal and squeak and drive me nuts! Next time i pull the rotors im putting mine back on.just my .02
I second that. I did the backing plate elimination when I originally did my SAS and hated it. It's probably fine it you live in a dry clean climate but it gave me problems for snow wheeling when chunks of concrete like mud/ice freeze on the rotors and when you start moving again, horrible ker-pow!. Somehow the backing plates keep your rotors way cleaner. We have miles of gravel here and I got the gritty scraping nasty itchies without the backing plates. Backing plates rule.
