PowerStop AR8668SCR Disc Brake Rotor - Rear

Rear coated brake rotor for OE-style replacement

PowerStop AR8668SCR is a rear disc brake rotor built as a direct bolt-on replacement for original equipment. It is engineered for vehicles that need the same fit, weight, and vane count as the factory part, with corrosion protection on exposed areas for a cleaner appearance behind alloy wheels.

Key features

• Part number AR8668SCR for easy identification and ordering.
• Partially coated design with silver epoxy on the hat, outer edge, and vanes.
• Vented, full cast construction with a smooth surface finish.
• Mill balanced for consistent rotor operation.
• Matches original equipment performance and specifications.

Detailed fitment and design

Compatible with rear brake applications on the Chevrolet Captiva Sport, Saturn Vue, Chevrolet Equinox, Pontiac Torrent, and Suzuki XL-7. This rotor uses a 303 mm outside diameter, 20.00 mm nominal thickness, and 18.40 mm discard thickness, with a 5-lug bolt pattern and 115.00 mm bolt circle diameter. PowerStop AR8668SCR is a practical choice for drivers replacing a worn rear brake rotor on a Chevrolet Equinox, Saturn Vue, or related platform vehicle while keeping OE-style dimensions and vented rotor construction.

What this rotor helps address

• Brake pulsation caused by rotor wear or uneven surface condition.
• Corrosion on exposed rotor areas that can affect appearance.
• Noise or vibration from a rotor that no longer meets spec.
• Fitment issues when replacing a factory rear rotor with the wrong dimensions.

Installation notes and quality assurance

Install as a direct replacement for the original rear rotor on listed applications. Verify outside diameter, thickness, bolt circle diameter, and vented construction before installation. This part cross-references Suzuki/GM OE numbers (e.g. 55611-78J00, 15223784) for the same application.

PowerStop designs these rotors to match original equipment specifications, including weight and vane count, for confirmed fitment on the listed vehicles.

AR8668SCR is the part number to reference when confirming application details for a Chevrolet Captiva Sport, Pontiac Torrent, or Suzuki XL-7 rear brake service.
