These are R4-S performance pads for the 2019 Porsche 718 Boxster S. This set covers both the front and rear axle positions, matched to the 2019 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 718 Boxster S that translates to a firmer pedal and more confidence when the pace picks up.
