What is the main benefit of a drilled brake rotor?

Drilled rotors have holes that help vent hot gases and brake dust away from the pad surface. This can lead to more consistent braking performance, especially under heavy use.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. Any necessary installation hardware, such as lug nuts or brake clips, would typically need to be purchased separately.

How do I know if I need to replace my brake rotors?

You should consider replacing your brake rotors if they are worn below the minimum thickness specification, have deep grooves or scoring, or if you notice pulsing or vibration when you apply the brakes.

Product Details

When you're replacing the brake pads on your vehicle, it's a good time to inspect your brake rotors. If they're worn thin, grooved, or warped, it's time for a new set. This GO-4 rear left drilled rotor from R1 Concepts is designed to be a direct replacement for your factory rotor.

The GO-4 series features a drilled surface. These holes help to vent hot gases and dust away from the pad surface, which can improve braking performance, especially during repeated stops. The black finish on the rotor helps to resist rust and corrosion, keeping your braking system looking good. It's a well-built rotor that offers a noticeable improvement over a standard, plain rotor.
