Manufactured using premium disc blanks*, 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).

*EBC Premium Disc - EBC is proud to be one of the only companies selling a British manufactured brake disc programme. 100% of our discs are made in our own casting foundry in the UK from a unique material called "discalloy".
This high quality grey iron includes copper to increase thermal conductivity and wear properties.

All EBC Premium Discs are cast to a material strength of 150 N/m2 with a tightly controlled surface hardness variation less than 20 HB and are precision CNC machined to a surface tolerance of less than 0.001 mm.

So you see this is no cheap import brake disc. These brake discs have the highest integrity and product quality on the aftermarket. An OE quality replacement disc, made of the finest grade steel and a perfect replacement disc for any car.
