I would simply recommend not fitting the anti-squeal plate to any aftermarket rear pads that are greater in overall width than 7.7mm each side.
The Ferodo replacements that I used seemed much thicker than they should have been although I didn't have any OEM available to compare with. I suspect I got a defective, over thickness set?
I have spoken with a BMW trained tech who has his own independent workshop. He only uses Brembo pads (my spare Brembo set measure correctly at 7.7mm) and he does use the backing plate.
I spoke with another mechanic who works on BMWs and he never uses the backing plate on any aftermarket pads!
If anyone fits the backing plate with replacement pads and has any issues with binding I'd suggest removing it. I went down the road of possible sticky pistons or sticky calliper pins and think that was a false avenue which led to other issues.
The Ferodo pad on the inside nearest the wheel wore down to the very limit in less than 4,000 miles (compared with the originals at 30,000) and the disc is a mess.
