All EBC rotors including USR Slotted Rotors are British made and are precision machined in the UK. Rotors are made from high quality grey iron 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 feel confident their approach is as perfect as it gets.

We are of the opinion that slotted rotors have been “Over sold” by certain marketplace participants and our findings are that a slotted rotor will only give benefits if used with a pad that compensates for its reduced surface area.

EBC Brakes USR slotted rotors can be ordered from any stockist or purchased ONLINE in the UK at:

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 brakes.

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.

Ultra quiet sport 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!).


There are two main reasons for brake vibration. The first is steering geometry issues and the second is installation or hub run-out issues.

GEOMETRY ISSUES – One in seven cars suffers geometry problems during its life that can affect steering and cause brake vibration. These are NOT a product quality issue!!!!!!.These can happen by simply nudging a kerb or by driving over a pothole. EBC is not alone in recognising this problem but is the only brake supplier on the planet prepared to offer diagnosis and a SOLUTION.

INSTALLATION OR HUB RUN-OUT ISSUES – These cause what is known as DTV. The videos below show how to correct for brake vibration caused by DTV (Disc thickness variation). DTV develops in a car after 3000-4000 miles caused by runout built in to the car or due to incorrect alignment of the rotors at install. This is quite a common fault on modern cars and many cars require this at every rotor change. Drivers also confuse hub distortion with a rotor quality issue but in 99% of cases the DTV is a car problem, not a rotor quality problem. You can replace the rotors as many times as you like trying to solve vibration and the problem will only go away for a few thousand miles and then return. This means you have purchased new rotors in good faith but the problem IS NOT SOLVED AND WILL NOT GO AWAY PERMANENTLY until you perform this procedure. After this skimming of the rotor surface you will have smooth brakes , more effective brakes and ZERO vibration. It is even a very worthwhile practice when fitting new rotors to have all four rotors skimmed into perfect alignment on your car with this inexpensive procedure. Rotor distortion due to DTV is very common, in fact ONE IN SEVEN CARS has a steering geometry problem either when it is built NEW or after nudging a kerb or hitting a large pothole (very common after road surface damage after winter snowy periods). Uneducated people still say “My rotors are warped”. Well the engineering facts are ROTORS DO NOT WARP, they are made of cast iron, they are very tough and can be run to red heat and cooled time after time and they will not distort, we do this day in day out on our dynos in the EBC lab. Thats why the whole world still uses cast iron as a vehicle brake rotor material, there has never been anything to beat it and probably never will be. Pro Cut machines WORK ON BOTH PLAIN ROTORS AND EVEN BETTER ON SLOTTED AND DRILLED ROTORS OF ALL TYPES.


Who are Pro-Cut ????… Pro Cut are a USA based multi national and extremely professional Corporation. Their machines are used and approved by many major car manufacturers and used all over the world to do exactly what they do best, CORRECT for rotor mis-alignment no matter how it arises on a car. You cannot achieve this with any other device.

  1. I have Citroen Berlingo Multispace, been back to the dealers twice about poor brakes & been told they are OK but I was still not too happy. Swapped the front discs for USR’S & fitted Ultimax pads, wow, what a difference, I am now much more confident with the brakes. Also just put some of your shoes on the rear of the car, OMG, I cannot believe the difference. Instead of feeling that the car is slowing down under hard braking I am now held in on my seat-belt. “Thank you” for wonderfull products, the cost was nominal but the difference is staggering. I just wish I had made the changes earlier.

  2. I wanted to tell you that I absolutely love the pads and rotors! Incredible. The product is so good that I will be purchasing EBC’s for my parents. They are getting older and the stopping power with your pads are incredible. Thank you my friend for everything!

  3. Well I just wrote a review for the Redstuff pads that I purchased along with these rotors and I must say I AM VERY IMPRESSED! The quality of these rotors are far superior than anything else out there! My suggestion to all prospective customers is Purchase The Pads along with these rotors. IT MAKE A BIG DIFFERENCE!!!! Great job guys, I am an EBC customer forever!!! my parents are getting older and next on my list is upgrading thier vehicles rakes to EBC. ABSOLUTELY AWESOME!!!!

  4. After “fighting” with the dealer on the chatter in my brakes from the beginning when hot, I felt they wouldn’t honor the warranty, I upgraded to EBC dimpled/slotted rotors and EBC dustless pads. The chatter was gone and the braking is much better. Even my wife has commented on the improvement in braking in her ’06 Cheverlot HHR. I liked the improvement in braking so much, I replaced the brakes on my ’07 Ford Ranger with EBC dimpled/slotted rotors and EBC dustless pads. Again, the improvement in braking is very noticeable. Thanks for a great product. A much needed improvement over factory brakes!

  5. These rotors are really good and a lot more quiet then most slotted rotors. thanks, I will suggest them to all my friends.

  6. Dixque et plaquettes EBC, vraiment un bon freinage, le seul petit défaut mais on s’habitue , c’est qu’au freinage il a toujours une genre de grondement, j’ai fait vérifier par mon mecano mais tout est correct.

  7. Just received my new rear EBC USR slotted rotors and Yellowstuff pads for my Audi A4 B6 Quattro Avant. I wanted to drop you a email and say what a great product both are. From the packaging to the products themselves, all received in perfect condition. The rotors look stunning and it will be so nice not to have rusted rotors in the Spring. Winter can be quite harsh here with -40oC – so we take our driving seriously. Being British, it is also fantastic to know the product is designed and engineered in the UK. Next year I will be replacing the fronts and will definitely be ordering EBC again!

  8. I’m writing to tell you how pleased I am with the Ultimax discs and pads on my 2006 Toyota Avensis.
    The original fitment Bosch discs and pads were noisy and produced much dust on the front wheels. The discs had worn 0.080 of an inch in 25000 miles and needed replacement.
    The Ultimax discs have only worn 0.005 of an inch in a further 25000 miles. Very impressive.

  9. I never thought stopping could be so much fun! The difference in braking performance over the stock brakes on my 2010 328i X-drive Coupe is simply astounding. The bite with even light pedal pressure is prodigious.

    Stopping from 45 mph happens in one car length. I’ve tried going deep on off-ramps from 80 mph and I can’t even make it dramatic – the EBC Greenstuff brake pads and USR rotors reduce speed so quickly that what I thought was a really late brake seems like nothing. I’ve got to be careful with passengers in the car because they are momentarily terrified if I try one of these manoeuvres – until they see how well the vehicle decelerates.

    Thanks for providing a great product. I’ll be glad to recommend them to anyone.

  10. My USR rotors have at least 25,000 miles on them, I have had three different sets of Pads on them and they have like no wear on them. They are on a 675rwhp 2011 mustang that gets drag raced and runs 10.028 and 139mph.

    I just replaced them with another set of the exact same EBC rotors, as I am trying a new pad compound, and wanted to start fresh.

    Just wanted to let you know how well they held up.
