I agree it is not much of a heat shield and heat sink, its' primary job is to reduce noise. I am starting to believe that it does help as I have melted the rubber booties in every car I have owned. The pads are retaining or building so much heat that it is being transferred to the piston boot, of course with some cars faster than others. The shims might not do much, but it might lower just enough for the rubber to maybe not melt since the two little metal plate can slow down the transfer of heat. The difference might be small, but I don't see why it would hurt assuming I can get it for cheap. I can live with the extra 6 oz on the car. Now the question is, where can I get it for less than $40 per corner!!!! Titanium will definitely work better, but aluminum can't hurt either....
