What is the main benefit of drilled and slotted rotors over standard ones?

Drilled and slotted rotors help manage heat and gas buildup more effectively than plain rotors. The holes and slots allow gases and heat to escape from the pad surface, which can lead to improved braking performance and reduced brake fade, especially during heavy braking.

Does this rotor come with any hardware?

This product includes the brake rotor only. You will need to reuse your existing hardware or purchase new hardware separately for installation.

How do I know if this is the correct rotor for my vehicle?

This rear left rotor is listed as a direct fit for specific Polestar and Volvo models and years, including the 2016-2018 and 2020-2025 Volvo XC90. Always double-check the fitment information against your vehicle's make, model, and year.

Product Details

R1 Concepts is known for making well-built brake components, and this rear left drilled and slotted brake rotor is a solid option for your Polestar 2 or Volvo. If you're looking to improve your braking performance beyond stock, especially under harder use, this rotor is a good step up. The drilled holes help vent gases and heat away from the pad surface, while the slots help keep the rotor clean and provide a consistent bite, even in wet conditions.

This rotor is built with a black finish, which helps prevent rust on the non-friction surfaces, keeping it looking good and resisting corrosion. It's designed as a direct replacement for your original rotor, meaning it fits right without modification. The combination of drilling and slotting is a popular choice for drivers who want a noticeable improvement in braking feel and fade resistance compared to plain rotors.
