What is the benefit of drilled and slotted rotors?

The drilled holes allow heat and gases to escape from the rotor surface, preventing brake fade. The slots help to sweep away dust and moisture, ensuring consistent contact between the brake pad and rotor for better stopping power.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. Installation hardware, such as lug nuts or brake pads, is typically sold separately.

What does the black finish do?

The black finish on the rotor provides an added layer of protection against rust and corrosion. It also contributes to the overall appearance of the braking system.

Product Details

R1 Concepts is known for making well-built brake components, and this front left drilled and slotted rotor for your 2007-2010 Chevrolet Cobalt is a solid example. If you're looking to improve your braking performance, especially under harder use, this rotor is a good choice.
