StopTech Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers. The 127.47030R Slotted & Drilled Sport Rotor (Right Front) fits 2008+ Subaru STI models (5x114.3 bolt pattern). These rotors offer improved cooling and shorter stopping distances thanks to the cross-drilled and slotted surface which helps wipe away debris and gases. Features include: high-quality G3000 metallurgy, E-Coating for permanent corrosion resistance, and a cooling vane design that shed heat much better than standard rotors. This part is a single right-hand side rotor. For a complete front set, please also order part number 127.47030L. Note: Will not fit 2005-2007 STI models due to specific fitment requirements.
