What is the benefit of slotted brake rotors?

Slotted rotors help to improve braking performance by clearing away brake dust and gases. This maintains better contact between the brake pad and rotor surface, leading to more consistent stopping power, especially under heavy use.

What material is this brake rotor made from?

This brake rotor is constructed from durable cast iron, which is known for its strength and ability to withstand the heat generated during braking.

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.

About this part

Product Details

These R1 Concepts slotted rotors are made from a durable cast iron that can handle the heat generated during braking. The slots cut into the rotor surface are a key feature, helping to sweep away brake dust and gases that can build up between the pad and rotor. This helps maintain a consistent contact patch, which means more reliable stopping power, especially during repeated hard braking.

Specifically for the rear left position on your 2003-2006 BMW Z4, this rotor is designed to fit right without modification. The black finish isn't just for looks; it offers some protection against rust and corrosion, keeping the rotor looking good and performing well over time. It's a solid option if you're looking to replace worn rotors and want something that offers improved performance over a standard, plain rotor.
