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

The angled slots are designed to pull in cooler air, which helps keep your rotors and brake pads at a more optimal temperature. This improved cooling leads to more consistent braking performance, especially under load.

Will these rotors make a lot of noise?

EBC designed these Ultimax slotted rotors to minimize the air noise often associated with slotted rotors. The progressive angle of the slots helps achieve the benefits of slotting without the excessive noise.

What brake pads are recommended for these rotors?

These EBC Ultimax rotors are designed to be used with brake pads that match FMSI pad number D1111. Using the correct pad type is important for optimal performance and longevity.

Product Details

When you're looking to replace the front brake rotors on your 2004-2008 Audi S4, especially if you push your car a bit, EBC's Ultimax slotted rotors are a solid option. These aren't just plain replacement rotors; they've got a special design that helps your brakes work better, especially during spirited driving.

What sets these apart is the way the slots are cut. They're angled progressively, which is a clever way to get the benefits of slotted rotors—like better cooling and dust clearing—without that annoying air noise you sometimes get. The angled slots actually help pull in cooler air, keeping your rotors and pads from getting too hot. This means more consistent stopping power when you need it. Plus, the slots sweep away brake dust and debris, which helps your brake pads grip better and can even make them last longer.

These are vented rotors, designed to fit your S4's front axle. They're made to be a direct replacement, so installation should be straightforward, assuming you're comfortable working on brakes. You'll be using FMSI pad number D1111 with these rotors.
