StopTech Sport Drilled & Slotted Brake Rotors are 1-piece direct replacement brake discs for your factory brake system and stock calipers. These rotors provide improved cooling and better bite compared to stock rotors. The cross-drilling and slotting help wipe away debris and gases that form between the pad and the rotor during braking. This specific part (127.34144R) is for the Rear Right (Passenger Side) position. Key features include: protective black e-coating on non-frictional surfaces for corrosion resistance, advanced metallurgy to prevent cracking, and improved heat dissipation. This is a single rotor (1 piece). Included components: 1x StopTech Sport Drilled & Slotted Rear Right Rotor (P/N 127.34144R).
