R1 05-18 Audi A3 Rear Left Drilled Black Brake Rotor

The drilled holes on this R1 Concepts rear brake rotor are specifically designed to help vent gases and moisture away from the braking surface. This helps keep the rotor cooler, especially during hard braking, and can improve stopping performance by reducing fade. It's made from a solid cast iron material, which is a standard choice for brake rotors because it offers good thermal mass and durability for everyday driving.

This rotor is intended for the rear left side of your vehicle. The black finish is applied for corrosion resistance, helping to protect the rotor from rust, especially in areas with a lot of road salt or moisture. It's a direct replacement for the original rotor, meaning it should fit right onto your existing brake system without needing modifications.
