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. D331

• Ultimax OE Style Disc Kit

Upgrade the braking performance of your 1993-1996 Mazda RX-7 Twin Turbo with EBC Ultimax Slotted Front Brake Rotors, part number ebcRK644. This premium OE-style disc kit is engineered for dependable street performance and is designed to work with FMSI pad number D331 applications. The rotors provide the functional advantages of slotted braking surfaces while maintaining quiet operation during normal driving.

Progressively angled slots help draw cool air across the braking surface, supporting more consistent brake performance during repeated stops. The slot design also helps evacuate excess dust, gas, and debris from between the rotor and pad, promoting strong pad contact and helping maximize pad service life. Unlike many aggressively slotted designs, the angled slot pattern is intended to reduce the excessive air noise often associated with slotted rotors.

EBC Ultimax rotors are a practical choice for drivers seeking improved brake control, heat management, and reliable replacement performance without an overly aggressive track-focused design. This kit is intended for the front axle of compatible 1993-1996 Mazda RX-7 Twin Turbo models with vented rear rotor configurations. Verify vehicle application and pad compatibility before installation.
