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

The progressively angled slots on these EBC Ultimax rotors help to clear dust and debris from the pad surface, which maintains maximum pad grip. They also help to pull in cooler air, which keeps the brakes operating at their best.

Will these slotted rotors make a lot of noise?

EBC designed these Ultimax slotted rotors to offer the performance benefits of slots without the excessive air noise often associated with them. The specific slot pattern is engineered for quieter operation.

What other parts are typically replaced when installing new front rotors?

When replacing your front rotors, it's common practice to also replace your brake pads. For these rotors, the manufacturer specifies FMSI Pad No. D1223. It's also a good time to inspect your brake fluid and potentially replace it.

About this part

Product Details

When you're looking to refresh the braking system on your Mercedes-Benz CL550, S550, or other compatible models, replacing your front rotors is a key step. These EBC Ultimax slotted rotors are designed to give you the benefits of slotted rotors without the common whistling noise. The progressively angled slots are a smart design choice that helps pull in cooler air, keeping your brakes working at their best, especially during harder stops. They also do a great job of clearing away dust and debris, which helps your brake pads grip better and can even extend their lifespan.

These rotors are well-built and feature a vented design, meaning they have internal vanes to help dissipate heat. The specific slot pattern on these Ultimax rotors is engineered to reduce air noise, so you get improved performance and longevity without sacrificing comfort. They fit right into place as a direct replacement for your original equipment, making the installation process straightforward. With a 350mm diameter and 32mm thickness, they match the specifications of many premium Mercedes-Benz models from the late 2000s and early 2010s.
