StopTech Sport Drilled & Slotted Brake Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers. This part (127.34145L) is for the Rear Right position. It features a unique cross-drilling and slotting pattern that aids in heat and brake dust dispersal, prevents pad glazing, and improves braking performance in wet and dry conditions. The rotors finished with a black e-coating for long-lasting corrosion protection. This item is a single rotor (1 piece). Included components: 1 x StopTech 127.34145L Brake Rotor. It is highly recommended to replace rotors in pairs (Left 127.34145R and Right 127.34145L) for balanced braking performance.
