This Porterfield brake pad set fits Porsche 997 GTS with Iron Rotors (2011) for front and rear braking applications where the selected compound and position match the vehicle. Porterfield has served performance street, autocross, racing, and motorsport brake customers for decades with brake pads, brake shoes, and related braking components.

Compound options include R4-S for performance street and autocross use, R-4 for race-focused temperature ranges, R4-E for longer high-temperature endurance use, and R4-1 where that compound is preferred for the application. Porterfield-branded components are intended as direct-fit brake components for Porsche applications when matched to the correct position, compound, and brake package.
