Porterfield R4S brake pads, rear, 2001-05 Sport size

This is our favorite all-around pad. It'll work well on the street, the autocross course and even light track use. Quiet, slightly higher effort than stock pads. Not recommended for full on road race use in the front as they will likely overheat. Carbon Kevlar construction.

Fits the rear brakes on 2003-05 US Miatas, often called "Sport". They also fit the optional Sport brakes on 2001-02 US Miatas. These do not fit the smaller "1.8" brakes, which were found on 2001-02 cars that came with factory 15" or smaller wheels. Cars outside the US built after 2002 may use the 1.8 brakes.

To confirm you have the correct parts, you can call Flyin' Miata or measure your front rotor diameter. The rear rotor diameter for the 1.8 brakes is 9.9", the Sport brakes are 10.9".

Does not include replacement springs, clips and other hardware. One box (quantity 1) has enough pads for one axle or two calipers.
