Front Pad Change - To Replace Dampening Discs or Not? Caliper Service?

For some time (well, a month of two) my 944 has been getting a little low on the pad material front (around 3mm is still left) on the front axle. I'd normally let them go on a little longer (and probably change the discs) but the brake disc prices on this setup are quite frankly scary and thankfully they are still within the specified wear limits! Acquiring a set of genuine Porsche pads for a reasonable rate took the choice out of my hands as to which pads to go for (I.e either Pagid (where some believe the quality is not what it once was;some reckon ECP has bought part of the brand out) or Textar).

My next question are regarding the dampening discs. I have no idea whether my car has these fitted but for now I shall assume that it has. Before I go to tackle the car I thought I would see what your thoughts are on these. I noticed that some members mention that they do not run these on the rear of the car, yet others reckon they could get away with some grease on the backing plates on the pads up front. What have you chaps tried, and work works? Is it best to go with 'OE' type discs or to an OPC?

Furthermore my callipers all round seem to be in very good condition and tend not to squeal. From looking and them and the history of the car I would say the brake setup is no older than 5 years old given the mileage the car has covered (somewhere between 15-20k) and are generally in good order. I shall assume for now that the 928 GTS callipers up front have the same plate problems that afflicts Porsche Brembo callipers. Is it work removing the plates, regreasing beneath the plates with either brake or copper grease and then reassembling them? Or will I simply cause more issues than preventing them by doing the above?
 
I've never used the dampening discs, never found it a problem. I use moly grease on the pads - seems to last much longer than copper.

If the pads are moving freely, do you need to worry about plate lift? Sure it could be preventative, but you'll find plenty of posts on here about the difficulties in removing the screws holding the plates in.
 
I found I had to use the dampers on the front but not on the rear. I have M030 brakes. I couldn't get the squeal to stop without the dampers. Tried different pads, discs, copper grease, some sort of Bosch anti squeal paste and couldn't get acceptable results until I bit the bullet and got the OEM dampers. £20 each x 4 [:eek:]
