R4-S - For high performance and heavy duty street conditions, the R4-S compound remains a top performer in the realm of street/performance brake pads. Perfect for everyday street driving while also being capable of enduring the most severe street use without fade. It is rotor friendly, low dust and squeal. We have gone to great lengths to ensure it is the absolute lowest noise and dust levels produced for a performance street compound. With this pad compound you will increase the friction level of your pads resulting in quicker stops. The pads will last longer and be more quiet and produce less dust than your current OEM pad.
All Porterfield brake pads are solely developed for Motorsport use. They are intended for race use only. They have not been developed for use on public roads and must not, under any circumstances, be used on public roads.
