350mm rotor pad size
I run pfc pads up front on my car. With 997 sized 350 rotors I use 991 sized pads up front. I noticed some floating rotors call for using the 7819 size pad because of a smaller friction surface. I'm thinking about going to girodiscs up front for this year. How do I know what pads are correct, 991 or 7819 (the friction surface is 65mm vs 62mm on these)

Different size pads fit. They match the rotor. In this case the answer is the same pad... girodiscs use the 0991, however if you use 350mm rotors from pfc, they use the 7819 pad...
