These are the very expensive but outstanding Pagid RS29 brake pads (E8028 R20 01) that will fit various big brake kits. (please check model no). These were fitted to my Alcon Advantage Extreme (Pro R) front 365mm brake kit. The standard Ferrodo DSP pads that came with the kit were utter rubbish! They were on the car for just a few months in which I did just 2 trackdays. They are hardly worn as can be seen in the photos. These normally retail for £280.

Any ideas if these will fit the Porsche GT3 calliper...I know they will need to be machined to fit perfectly

 

I woud find out the Porsche GT3 pagid part no and see if it matches.
