PowerStop AR8661XPR Disc Brake Rotor Set - Front

Overview

Power Stop AR8661XPR is a drilled and slotted brake rotor set built as a direct OE-fit upgrade for improved cooling and cleaner rotor contact. It is compatible with select Chevrolet Uplander, Pontiac Montana, Buick Terraza, and Saturn Relay front brake applications.

Key Features

• Cross-drilled and slotted surface helps move heat, gas, dust, and moisture away from the rotor face.
• Silver zinc dichromate plating adds rust and corrosion resistance.
• Vented rotor construction supports heat management during repeated braking.
• Direct OE fit reduces the need for special modifications.
• Part number AR8661XPR for application matching and catalog lookup.

Detailed Description

This Power Stop disc brake rotor set uses a slotted X-drilled design with a vented rotor body and a 11.70-inch outside diameter. The 115 mm bolt circle and 6-lug pattern align with the listed fitments, while the plated finish helps protect the rotor surface from corrosion. For buyers searching for a front brake rotor set for a Chevrolet Uplander, Pontiac Montana, Buick Terraza, or Saturn Relay, AR8661XPR provides an OE-style replacement with performance-oriented surface treatment.

Power Stop’s drilled and slotted rotor line focuses on cooling, surface cleaning, and consistent friction contact under demanding braking conditions. AR8661XPR follows that approach with rounded slots and precision drilling for applications where heat control and rotor surface maintenance matter. If you are replacing worn front rotors on a Chevrolet Uplander or Pontiac Montana, this part number AR8661XPR is built to match the listed OE-style fitment.

What It Helps Address

• Brake fade from heat buildup during repeated stops.
• Rotor surface glazing caused by trapped gas and debris.
• Rust and corrosion on exposed rotor surfaces.
• Uneven friction contact from moisture or dust on the rotor face.
