StopTech Sport Slotted Brake Rotors are premium 1-piece replacement brake discs for factory brake systems. These rotors feature specialized slotting that significantly improves braking performance by wiping away debris and gases, ensuring consistent pad contact and preventing glazing. This item is a single Left Front rotor (Part No. 126.40094SL). Key features include: high-carbon metallurgy for reduced noise and increased crack resistance, black e-coating for superior corrosion protection on non-friction surfaces, and a cooling vane design for effective heat dissipation. This component is part of a balanced braking setup; for a complete front axle installation, it should be paired with the Right Front rotor (StopTech Part No. 126.40094SR).
