This Porterfield brake pad set is built for Porsche 997 Turbo with Iron Rotors & Center Lock Wheels (2012) for front and rear brake applications. Porterfield is a long-established brake supplier with deep experience in performance street, autocross, racing, and motorsport brake applications, including 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.
