These are R4-S performance pads for the 2006 Porsche Boxster S running the ceramic-rotor brake package. This set covers the rear axle position, matched to the 2006 brake setup rather than a generic catch-all fit.
Porterfield's R4-S compound is built for owners who still drive on the road but want stronger, more heat-stable braking than stock pads deliver. On a Boxster S that translates to a firmer pedal and more confidence when the pace picks up.
Because Porsche varied pad fitment by rotor material and caliper across the Boxster S run, verify the 2006 application and the notes below before you buy. We are happy to check your VIN.
