How do the slots on these EBC rotors help?

The angled slots on these Ultimax rotors help pull in cooler air to keep your brakes from overheating. They also sweep away brake dust and debris, which helps maintain good pad contact and can extend pad life.

Will these slotted rotors be noisy?

EBC designed these Ultimax slotted rotors to offer the performance benefits of slots without the excessive air noise often associated with them. The progressive angle of the slots contributes to quieter operation.

What is the main difference between these and standard OE rotors?

These EBC rotors feature a slotted design that helps with cooling and dust evacuation, unlike standard OE rotors which are typically smooth. They are also vented, which is common for performance applications to manage heat.

About this part

Product Details

If you're working on your 1997-2000 BMW 528i or the 2001-2003 525i, these EBC Ultimax slotted front rotors are a solid option. They're designed to give you the benefits of slotted rotors, like better cooling and dust removal, without the extra noise you sometimes get with other slotted designs. The angled slots help pull in air to keep things cool during hard braking, which means more consistent performance when you need it most.

Beyond just cooling, these slots also help sweep away brake dust and debris. This keeps your brake pads making solid contact with the rotor surface, which can improve stopping power and even help your pads last longer. They are vented rotors, meaning they have internal vanes to help dissipate heat, and they are a direct fit for the specified BMW models.
