Servicing the brakes on a 2005 Porsche Boxster S running the ceramic-rotor brake package? This R4-S pad set is cut for that exact application. This set covers the rear axle position listed in the listed applications.

The R4-S compound sits in Porterfield's street-performance range, giving a Boxster S firmer initial bite and more fade resistance under hard use while still behaving on a cold morning commute.
