What is the benefit of the drilled holes on this rotor?

The drilled holes help to vent hot gases and moisture away from the brake pad surface. This can lead to more consistent braking performance, especially during repeated hard stops or in wet weather.

What does the black E-coating do?

The black E-coating is applied to the non-friction surfaces of the rotor to protect against rust and corrosion. This helps maintain the appearance of the rotor and prevents rust buildup that could interfere with brake components.

Does this rotor come with any hardware?

This product listing is for the brake rotor only. It does not include any mounting hardware, such as lug nuts or brake pads. Please ensure you have the necessary hardware or purchase it separately.

About this part

Product Details

This R1 Concepts drilled brake rotor is made from a high-carbon iron casting, which helps to dissipate heat more effectively than standard gray iron. The drilling pattern on the rotor surface is designed to help vent gases and moisture away from the pad surface, which can improve stopping performance, especially in wet conditions or during hard braking. This rotor is specifically for the front left side of your 1977-1983 BMW 320i.

The black E-coating applied to this rotor offers corrosion resistance, helping to keep the non-friction surfaces looking good and preventing rust buildup. This rotor is a direct replacement for your original part, meaning it fits right onto your existing brake system without modifications. It's a solid option if you're looking to maintain or slightly improve your 320i's braking capabilities.
