Use this Porterfield brake pad set for Porsche 996 GT3 with Iron Rotors (2004) when the application calls for the listed front and rear brake position and compound choice. Porterfield-branded brake components are made for proper braking performance, fitment, and serviceability at the installed location.

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.
