Are the dampeners stuck on to the brake pads with an adhesive? Can they be reused?

This is what I'm going to be ordering unless you tell guys tell me something is redundant or I missed something.

1.Front brake pads (OEM)
2.Rear brake pads (OEM)
3.Front caliper repair kit (replacement springs, retaining pins, and spring cotter pins)
4.Rear caliper repair kit (replacement springs, retaining pins, and spring cotter pins)
5.Rear caliper bolts (4 total)
6.Front brake pad dampening set (should have 12 in the kit)
7.Rear brake pad dampening set (should have 8 in the kit)

TIA

 

Do you mean something like this?





Strange I don't have them in my rear calipers. And I'm 99% sure that I'm on my first set of pads (from factory). Just the caliper piston, some metal heat shield (I think) and the pad itself.
I have 2010 997TT (euro version).

BTW: Are the caliper piston inserts black or yellow in your car?

 

Do you have the dampeners from the first picture in yur calipers? The Porsche tech said that the new pads come with a dampening plate and loger use the pucks in the caliper pistons.
