R4-S brake pad set for the 2007 Porsche Boxster S running the ceramic-rotor brake package. This set covers the rear axle position, so it is a fitment-sensitive choice keyed to the 2007 car and the exact brake hardware it left the factory with.
R4-S is Porterfield's street-focused performance compound: more bite and better heat tolerance than a basic replacement pad, while staying civil enough for daily road use. It is a common pick for a Boxster S owner who wants sharper braking without moving to a full track pad.
