The StopTech Slotted & Drilled Sport Brake Rotor (Left Front) is a premium 1-piece bolt-on upgrade for your factory braking system. These rotors feature a cross-drilled and slotted pattern that provides improved heat dissipation, faster expulsion of brake dust and gases, and enhanced wet weather performance. The black e-coat finish protects the cooling vanes and non-friction surfaces from corrosion. This part number (127.34058L) includes: 1x StopTech Sport Left Front Brake Rotor. For a complete axle set, this must be paired with the right-side rotor (127.34058R).
