What is the benefit of slotted brake rotors?

The slots on the rotor surface help to sweep away brake dust and hot gases that can build up between the brake pad and rotor. This leads to more consistent braking performance and can help reduce brake fade during repeated stops.

What material is this brake rotor made from?

This brake rotor is constructed from a high-carbon iron casting. This material choice helps to dissipate heat more effectively than standard gray iron, which can contribute to more stable braking.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. It does not include brake pads or installation hardware. It is recommended to inspect your existing hardware and pads when replacing rotors.

About this part

Product Details

This rear left slotted brake rotor from R1 Concepts is made from a high-carbon iron casting, which helps to dissipate heat more effectively than standard gray iron. The slots machined into the rotor surface serve a practical purpose: they help to sweep away dust and gas that can build up between the pad and rotor, leading to more consistent braking performance, especially during repeated stops.

Designed as a direct replacement for your 2003-2004 Subaru Impreza, this rotor is finished in black to help resist rust and corrosion on the non-friction surfaces, keeping it looking good even after installation. The slotted design is particularly beneficial if you do a lot of spirited driving or find yourself in situations where you need to brake hard more than once. It helps maintain a cleaner rotor surface for better pad contact.

When you're replacing a rotor, it's always a good idea to inspect your brake pads and consider replacing them at the same time if they're worn. This ensures you're getting the best possible braking performance and longevity from your new components.
