Stock rear rotors on the 1994-2004 Mustang 4.6L Cobra handle typical driving, but performance driving exposes their limits quickly. EBC's USR Slotted Rotors sweep gas, water, and debris from the pad face on every revolution, keeping your braking consistent when it matters most.
Progressive slot geometry, not just slots. EBC machines the slots at a progressive angle across a narrower multi-slot pattern. That geometry promotes flat, parallel pad wear instead of allowing the ridges that form on drilled-only rotors. Parallel pad wear means consistent bite and pedal feel across the full service life of both the pad and rotor, not just when they are new.
R90-approved G3000 grey iron blanks. Every USR rotor starts from the same premium-grade grey iron castings required by European R90 brake certification. The material meets demanding hardness and metallurgical standards before a single slot is cut, giving the finished rotor a consistent, predictable heat response on hard stops.
Precision machined in the UK or USA. EBC manufactures 92 percent of everything it sells in its own UK or USA facilities. Bought-in components undergo batch metallurgy checks, X-ray inspection, dimensional verification, and balance testing before they reach the production line, so quality control is not outsourced along with the parts.
Designed specifically for fast street use. The USR range targets drivers who push their cars hard on back roads and the occasional track day but still need a rotor quiet enough for everyday driving. The narrower slot profile keeps wind noise and pad surface noise minimal compared to aggressive track-spec designs.
Product Benefits
- Direct Rear Fitment: Engineered specifically for 1994-2004 Mustang 4.6L Cobra rear applications.
- Progressive Slot Angles: Machined at a progressive angle to reduce noise while still clearing gas, water, and debris.
- Parallel Pad Wear: Slot design prevents ridge formation on pads and rotors for consistent braking throughout wear life.
- R90-Approved Iron: G3000 grey iron blanks meet strict European certification standards for rotor material quality.
- UK and USA Manufactured: Precision machined in EBC's own plants for tight dimensional and balance tolerances.
- Batch Quality Control: Every production run includes metallurgy, X-ray, balance, and dimensional inspection.
- Street-Silent Operation: Narrower slot pattern delivers sport rotor performance without the noise penalties of drilled designs.
About EBC Brakes: EBC Brakes produces friction materials and rotors across its own UK and USA manufacturing plants, covering the full spectrum from daily-driver upgrades to full race compounds. Vertical integration over the majority of their production allows EBC to control material quality at every stage, from raw casting to finished rotor.
