991 GT3 PCCB Replacement Iron Rotor Kit
We received inquiries form Porsche shops and GT3 owners to develop iron rotor kit replacement for 991 GT3 CCM rotors that are 410x36m front and 390x34mm rear.
Our response is yes we can, and we will add this development to our high profile brake kits which we offer for:CCM rotor is lighter in weight (about 1/2 of iron) but the strength and thermal conductivity is not as good as iron, so they have to be made larger and thicker than an iron (steel) rotor, but if we make the iron conversion with the same dimensions as the GT3 CCM, it will be too bulky and heavy.
To get around this we offer light weight kit like this for ZR1 which we make the rotor thinner and annulus narrower (w/modified pad) to save the weight w/o changing the diameter in order to fit the stock calipers.
Here is the weight comparison among CCM, Stock Iron, and Light Weight Iron:
See "mikymu" recent review on those light weight rotors on his ZR1:

However for GT3 with a diameter of 410mm if we are to make the same size of rotor for OE calipers, it will definitely too heavy and not necessary, and that's the idea of the complete RB caliper brake kit come in:
We would propose to offer 390x32/34 front, and 380x32/30 rear with RB 6-pot / 4-pot caliper, like those kits we developed for GT-R would be the right answer.
Let me know how you guys think.
Thanks

Adding some links to GT-R forums for the brake kits offer from RB:

Some caliper pictures (front 6 piston) with hard-anodizing finish that is heat and brake fluid resistant.
The calipers are built with "forged" 7075 aluminum alloy and assembled with 12.9 alloy steel high strength bolts for the ultimate strength and rigidity.
