The R1 Concepts slotted black rear left brake rotor for 2013–2017 Subaru WRX STI is a direct-fit replacement rotor with slotted surfaces and a black finish. The slots help clear pad residue and support consistent braking feel, while the finish offers a coordinated look for rear-left service or rotor upgrades on the listed WRX STI model years.
