The front pads are made by Galfer and the rears by Textar. You will see these names stamped in the metal backing plate. Brembo and Porsche also has their names on the pads in white paint. This doe not mean they are the best pads.
I have always been told the rotors are made by Zimmermann. Most shops and owners I know use Zimmermann to avoid the Porsche prices. However the hats on Zimmermann are not painted gray like Porsche. Just get some high temp gray paint.
The torque for the caliper bolts is 63 ft/lbs or 85 Nm.
Porsche says in the shop manual not to reuse the pin, clip, spring plate, and bolts But we do. So does my Porsche dealer. Jeff

Good article.
A warning though - Greig has mixed the metric and imperial settings for the torque setting. it should be 96ft/lb, or 130Nm. NOT 130 ft/lb.
Edit: Greigs now corrected it

This is a little bit bolting the door after the horse etc but. Whilst the zimmerman discs from ecp are indeed "original manufacturer" they are not obviously the original parts to Porsche quality standards. Porsche normally hold patent with the maker for their discs and zimmerman cannot supply them to anyone else in the same style or manufactured standard. Several Porsche parts suppliers will be able to supply you with Genuine Porsche part numbered and boxed discs at a cost considerably lower than your OPC.Parts prices can also vary from opc to opc. These will be made to Porsches standard and may last considerably longer than the O.E parts and may also produce significantly better standards of retardation.
Nic,
Here's that link I used.....

Good luck!

I think the "rights" to that particular design/spec would be what they own.
Sorry patent might not be the correct term to use. But Porsche has something made by an outside supplier for which they have the sole rights to in design and manufacture. So for instance Porsche brake pads may indeed be made by textar but Porsche own the rights to the design and "make up" of the "official" pad so textar can't sell that composition of pad to anyone else. As you will know brake pads can vary greatly in their friction coefficent and the same is true of brake disc composition.

Depends what you mean by "a brake disc".... [
]If you mean the simple concept of a disc attached to the axle with a pair of pads either side that can be squeezed onto the disc to slow the car down, then that is technology that is over 20 years old so any patent for it must be either expired or invalid.
However, there is nothing to stop anyone from inventing an new improvement in the field of disc brakes. If they do, and the idea is not obvious, they are entitled to file a patent application to protect that idea. However, a patent resulting from that application would only protect that improvement - it could not be used to stop someone from making ordinary brake discs, or brake discs with other unrelated improvements.
Laurence Gibbs is right, though; we are probably not talking about a patent here. More likely that we are in the field of design rights - these are similar to copyright but have major limitations to reflect the minor differences between making car parts and writing books. This is a complex area with various overlapping rights but, for example, UK design right can only be used to stop people copying for five years. For the next five years you can't stop them but you can ask for a royalty payment. And after 10 years, tough!

Sorry, but I'm not sure this is correct. I recently replaced the rear brake pads in my 996 and the Textar ones I used were exactly the same as the Brembo ones except the latter had a different 'label'. I've posted photos of this somewhere (boxa.net? PCGB? Porschaforum?) but I can't find them.
Paul,
you can't tell just by looking at the pads. Pad material (including the metal backing) is made up of a variety of different substances that increase or decrease a myraid of working tolerances, friction coefficent, longevity, noise and dust production(resistance to oxidation in the case of discs[]) to name but a few. Just looking at two pads would not neccesarily tell you anything other than they look the same.

I saved your picture of the rear pads. You will need to enlarge it to see the info stamped on the metal backing plate.
The back of the Textar pad has the name Textar and a Textar part number. The "Porsche Brembo" pad has the name Textar and the identical Textar part number on the back. The friction ratings of both pads are the same, FF. FF is also stamped on the back of both pads after the part number.
In my book that means they are identical. Except the price of course.
