What is the main benefit of drilled and slotted brake rotors?

Drilled and slotted rotors help improve braking performance by allowing heat, gases, and moisture to escape from the pad surface. This helps prevent brake fade and maintain consistent stopping power, especially during hard braking or in wet conditions.

Does this rotor come with any hardware?

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

What is the silver finish on the rotor for?

The silver finish on this R1 Concepts rotor is a protective coating designed to help prevent rust and corrosion on the rotor surface, especially before installation and during initial break-in.

About this part

Product Details

This R1 Concepts front left brake rotor features a drilled and slotted design, measuring 11.02 inches in diameter. The drilled holes help vent gases and heat away from the pad surface, while the slots help clear away dust and moisture. This combination helps maintain consistent braking performance, especially during repeated stops or in wet conditions. The rotor is finished in silver to help resist corrosion.

Built from a durable cast iron, this rotor is designed to handle the demands of daily driving. The drilled and slotted pattern is a popular choice for drivers looking for an improvement over standard, plain rotors. It's a direct replacement for your original equipment, meaning it fits right onto your 2003-2010 Chevrolet Cobalt's front left side without modification.
