What is the main benefit of the slotted design on these rotors?

The wide slots on these EBC rotors help to remove dirt, dust, and debris from the braking surface. This allows the brake pads to maintain consistent contact, which can help reduce brake fade under load and at speed.

What material are these EBC rotors made from?

These rotors are constructed from OE spec grey cast iron, which is the same type of material used in new car production. EBC manufactures many of their rotors in their own UK foundry.

Do these rotors come with any hardware?

This product listing is for the EBC GD Sport front rotors only. Installation hardware, such as lug nuts or brake pad hardware, is typically sold separately. Please refer to the manufacturer's installation instructions for a complete list of required components.

About this part

Product Details

These EBC GD Sport rotors feature wide slots, a design choice that helps your brakes run cooler. They're made from OE spec grey cast iron, the same material used on new cars coming off the assembly line. For your 2004-2008 Audi S4, these front rotors are vented and measure 345mm in diameter, 30mm thick, with a 68mm center hole diameter and 5 bolt holes.

The slots on these rotors do more than just look good; they help clear away dirt, dust, and debris from the braking surface. This keeps the pads making solid contact, which can reduce brake fade, especially when you're carrying a load or driving at higher speeds. For imported vehicles like your Audi S4, these rotors come with a gold anodized finish for protection.
