USR2150 - EBC USR Series - Fine Slotted Sport Front Brake Rotors - Audi B9 S4/S5/SQ5

The price you see is for TWO DISCS, one left one right. Another great feature of slotted discs is the way they MAINTAIN FLAT AND PARALLEL PAD WEAR and avoid the record grooves or galling, common with non-slotted discs. This improves pad contact and braking throughout the life of the disc and pad set. Another major benefit of the EBC Brakes fine slotted discs is their ability to totally resist cracking common with through-drilled discs.

Statement of Origin – EBC Brakes manufactures 92% of everything it sells in its own plants in the UK or USA. That’s impressive for a brake brand, likely one of the largest in the world.

About Slotted Rotors

All EBC rotors including USR Slotted Rotors are British-made and precision machined in the UK or the USA. The rotors are made from high-quality, R90-approved grey iron rotor/disc blanks to exacting standards and undergo extensive testing and rigorous quality control. Slotted rotors can significantly improve brake performance and longevity when used with a matching high-friction brake pad set. Having sold hundreds of thousands of brake kits, EBC Brakes feels confident that their approach is as perfect as it gets.

Ultra Quiet Slotted Brake Rotors

Manufactured using premium disc blanks mentioned above, the narrower multi slot design of the Ultimax sport rotor and the progressive angle at which the slots are machined creates a quiet running sport rotor that still has benefits of removing gas, dirt, water and debris and maintaining parallel pad wear. EBC have always been honest enough to say that the biggest advantage of slotted rotors is the fact that they promote flat and parallel pad wear rather than allowing ridges to develop on pads and rotors which is typical of “drilled only” sport rotors. By preventing these ridges brakes stay more consistent throughout pad and rotor wear life (simple physics!)

Why Slotted? The Benefit!

The benefits of degassing and promoting flat and smooth pad wear are a clear plus in favour of sport rotors but the trick is to opt for a matched set of brakes and not to just expect a slotted rotor to improve braking on its own. When used with higher friction EBC Redstuff, Greenstuff or Yellowstuff brake pads these rotors will deliver better braking.

The different slot pattern of the EBC USR Series has made this range a popular choice for drivers who desire improved sport braking with minimal air noise from the slots. The finer slot pattern is what makes these sport rotors more silent in operation whilst still offering pad degassing and removing dirt dust water and debris from the braking area.
