Does this involve anything more than the application of Blue Peter-style sticky-backed plastic (or some similarly low-tech solution) to the back of the pads?
I very very much doubt it, but I'd hope they also CopperSlip'd the caliper sliders, as this really isn't rocket science. the only reason these are an 'issue' on the 2012+ cars (even if a little singing in reverse could really be considered to be) is that they have been assembled with insufficient lubricant. I pulled mine apart and lube'd up and job's a good'un.
If you want to really have real issues with a car, try a Morgan 3-Wheeler and then you'll get some sympathy
