How do the slots on these EBC rotors help my brakes?

Are these rotors noisy?

EBC designed these Ultimax slotted rotors to offer the performance benefits of slots without the typical air noise associated with them. The progressive angle of the slots helps reduce noise.

What type of brake pads are recommended for these rotors?

These EBC Ultimax rear rotors are designed to work with FMSI pad number D1018. It's always a good idea to check the manufacturer's recommendations for optimal performance.

About this part

Product Details

EBC is known for making well-built brake components, and these Ultimax slotted rotors are a solid option for your 2004-2008 Audi S4 4.2. They're designed to give you the benefits of slotted rotors without the annoying air noise you sometimes get.

The progressively angled slots on these rear rotors do a couple of important things. First, they help pull in cooler air, which keeps your brakes from getting too hot during hard stops. This means they can perform at their best when you need them most. Second, the slots help sweep away brake dust and debris. This keeps your brake pads gripping effectively and can even help them last longer, while also improving pad longevity.

These are vented rotors, meaning they have internal passages to help with airflow and cooling. They are a direct fit for the rear of your S4, designed to work with FMSI pad number D1018.
