Sorry it took so long, but since this seems to be a grey area, I personally made a request to an answer to SpeedFreaks and their answer was:

There are a couple surfaces that need to be lubricated by a dry lubricant after they are cleaned of rust and debris: One is the small contact area between the caliper housing and the brake pad edge guides, the other is the back of the shim where the piston contacts the shim. Both should have a thin layer applied. In the odd case where the shim is sliding on the backing plate of the pad, you can place something there as well.. But the shim should not be loose, it should be static and typically the backing plate of the pad is painted - which will burn off from track abuse, as will the dry lubricant. So this all applies only to street use.

the dry lubricant does make more sense. I have used this stuff on a buddy's car in the past and it sets up more densely than the conventional brake grease.. http://crc-canada.ca/disc-brake-quie...lliliters.html

Another response from Speed Freaks in another thread:

Let me preface this by saying I never use shims on any of my vehicles but I have always been taught to apply the anti-squeel between the shim and the backplate if you're going to use it. I don't think there is any "problem" with also putting on the backside of the shim that comes in contact with the pistons other than it making a little bit of a mess.

It's just a personal choice on my end- I swap pads very often and don't like dealing with the mess of anti-seize. I test a lot of pads since I think it's very important to actually have firsthand experience with much of what we sell. I prefer to not use shims to get a better idea of the natural noise and bedding characteristics of a pad. Besides I only use track specific compounds in my S2000 since it's primarily a track driven car that sees maybe 5k street miles per year. In my m3 I just never felt the need even with street pads, almost all noise can be silenced with proper bedding even in some of the more aggressive pads. I'm currently running Project Mu Club Racer in my S2000 (track compound) and Endless MXRS (street/track compound, slightly more aggressive than MX72 and less aggressive than ME20) in my M3 with no shims in either and they are both silent during casual street use.
I have said this before and I still maintain that, more often than not, any excessive noise from a true street pad is because they have not been 100% properly bedded in. I do admit that some brake systems, the tolerances and the materials used are more susceptible to producing noise than other. Almost everyone with an IS-F runs shims religiously and there is nothing wrong with that but I don't think it's as necessary as most people seem to think.
