Description

EBC Ultimax Slotted Rotors offer you the performance of slotted rotors but without the air noise that is normally associated with slotted rotors. The progressively angled slots on the EBC Ultimax Slotted Brake Rotors offer quiet brake operation without that excessive air noise, while still allowing the slots to help keep your brakes cool. The angled slots pull in cool air for cooler brake operation which helps your brakes perform at their best. The slots also help to clear any excess dust and debris to help keep pad grip to a maximum while also increasing pad longevity.
