Hi.
Much as I agree with Lancerlot insofar as using OEM parts from Porsche, you're unlikely to get a better price anywhere for the parts than Euro Car Parts, specially when they stock Pagid and Brembo, both of whom are suppliers to Porsche from the factory.
I bought Brembo discs and Pagid pads for my 997 C2s three years ago for a smidge under £400 and though for some reason (I guess supply issues given the current situation) they're not listing Brembo at present, you can get Pagid Discs and Pads for about the same now using the ECP discount code - they've always got some kind of offer on.
Also, unless the warning light has come on you'll be able to re-use the wear sensors, so long as the fittings match the pads going onto the car. I ran into this issue when i did mine. Even though the front sensors fitted fine, I had to buy new sensors for the back as the connectors which slot into the pad were different. Pagid are all a flat kind of 'lozenge' type.
My damping pads were OK too. I just cleaned them up and re-used with a dab of copper paste on the face that meets the disc (NOT a lot, otherwise it'll end up all over the place)
Insofar as dust is concerned there's not much you can do about this unless you use a harder pad, (Pagid RS-14 Fast-road or RS-26 Track) which actually compromises performance during normal road driving unless you're a nutcase - not judging, hehe - or doing frequent track days. It's mostly a problem on the front due to the weight shift under braking, but I kind of got round this by giving all my wheels a proper deep clean, then putting on two coats of wax inside and out so the dust at least cleans off easy enough.
Also (again) a word of warning: The retaining pins that hold the pads in place are easy to tap out on the back, but be prepared for a fight to get the front pins out. Between dust and heat build-up it will be a proper chore. Once you've got them out, use a dab (again a dab, not bucket loads) of copper paste on each end where they fit into the caliper to ease removal in the future.
Phew - need a cuppa now.
