PowerStop EBR670XPR Disc Brake Rotor Set - Rear

Rear Brake Rotor Upgrade for BMW Z4

PowerStop EBR670XPR is a rear disc brake rotor set built for 2003-2008 BMW Z4 applications, including 2006 BMW Z4 rear fitment from 1/06. It combines drilled and slotted rotor surface design with a zinc-plated finish to support cooler operation, cleaner pad contact, and corrosion resistance.

Key Features

• Direct OE-fit rear brake rotor replacement for BMW Z4 applications
• Slotted X drilled surface helps move away dust, gases, and moisture
• Cross-drilled design supports heat dissipation during demanding braking
• Silver zinc dichromate coating helps resist rust and surface corrosion
• Vented rotor construction for rear brake service
• 5-lug mounting pattern with 120 mm bolt circle diameter

Product Details

Power Stop EBR670XPR is part of the Power Stop drilled and slotted rotor line, a product line focused on bolt-on brake upgrades that retain OE fitment while adding surface features for thermal management and pad cleaning. For BMW Z4 rear brake service, this rotor set uses an 11.60-inch outside diameter, 17.40 mm nominal thickness, 17.40 mm discard thickness, and 3.00-inch overall height. The vented design and slotted X drilled surface support consistent friction contact, while the zinc-plated finish helps protect the rotor in everyday driving conditions.

This part cross-references Raybestos Brakes 980393 for the same application. PowerStop EBR670XPR also aligns with OE-style replacement needs for BMW Z4 rear brake rotor service.

Common Problems It Helps Address

• Brake fade from heat buildup during repeated stops
• Uneven pad contact caused by glazing, dust, or moisture on the rotor face
• Surface rust and corrosion on exposed brake rotor surfaces
• Reduced braking consistency from worn rear rotors
• Noise and vibration associated with deteriorated rotor surfaces

Installation Notes and Tips

Fits 2003-2008 BMW Z4, rear. Fits 2006 BMW Z4, rear, from 1/06. Confirm rotor diameter, thickness, and bolt pattern before installation. Inspect pads, caliper hardware, and hub condition during brake service so the new rotor seats properly and the braking surface remains even.

Quality Assurance

PowerStop manufactures this rotor with precision drilling, slotting, and zinc plating to support consistent brake performance and corrosion resistance. The direct OE fit helps simplify replacement on BMW Z4 rear brake applications without special modifications.
