These R4 pads are the racing version of Porterfield’s R4-S brake pads. The R4 pads are built to handle track duty and racing, but aren’t ideal for street driving. Yes, they can handle it and aren’t terrible when cold, but they do make a LOT of noise and dust!

The product image comparing the new R4 pad to the used R4-S pad shows show the complete lack of chamfering on the R4 pad. The chamfering ensures the R4-S pads are smooth and silent, but reduces the surface area of the pad. While this is design is ideal for street use, the reduced surface area limits this pad’s ability to handle track duty. The R4, on the other hand, sacrifices quiet road manners for outright braking performance by having a more aggressive pad compound and maximum surface area.

A great way to handle both easy street driving and hardcore track days is to have a set of both the R4-S and R4 pads, and swap between as needed for street and track use.
