EBC Ultimax Slotted Front Brake Rotors for 2022–2023 Subaru WRX – RK7858

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. For FMSI Pad No. D2045

• Ultimax OE Style Disc Kit

Upgrade the braking performance of your 2022–2023 Subaru WRX with the EBC Ultimax Slotted Front Brake Rotor Kit, part number RK7858. Designed as an OE-style disc kit, these rotors provide the benefits of slotted braking surfaces while maintaining quiet, refined operation. The progressively angled slots are engineered to minimize the air noise commonly associated with slotted rotors, making them well suited for daily driving and performance-oriented street use.

The angled slots help draw cooler air across the braking surface to support consistent brake operation under repeated use. They also assist in clearing excess dust, gases, and debris from between the rotor and pad, helping maintain pad contact and braking grip. By reducing buildup on the friction surface, the EBC Ultimax rotors can also help promote more even pad wear and longer pad service life. This kit is designed for applications using FMSI pad number D2045 and should be matched with the correct vehicle configuration before installation.

Each rotor is manufactured for direct replacement of the original front brake discs, helping simplify installation without requiring modifications to the vehicle. Confirm fitment against your Subaru WRX model, brake package, and application requirements before purchase. Professional installation is recommended, and all brake components should be inspected and properly bedded according to the vehicle and pad manufacturer’s procedures.
