Overview

PowerStop AR8287XPR is a rear disc brake rotor set built for direct OE-style replacement and upgraded braking performance. It fits 2005-2008 Pontiac Grand Prix, rear, and uses a drilled and slotted design with zinc plating for added corrosion resistance.

The AR8287XPR combines cross-drilled cooling paths with rounded slots that help clear gas, dust, and moisture from the rotor face. That keeps the friction surface cleaner under repeated stops and in demanding driving conditions.

Key Features

  • Drilled and slotted rotor design for improved heat management and surface cleaning.
  • Silver zinc dichromate coating helps resist rust and corrosion.
  • Vented rotor construction supports consistent brake performance.
  • Direct OE fit with no special modifications needed.
  • 12.00-inch outside diameter and 5-lug bolt pattern.

Detailed Description

PowerStop AR8287XPR is a rear brake rotor set engineered for drivers who want a direct replacement with added thermal control and surface cleanup. The drilled and slotted pattern is intended to improve cooling and maintain a cleaner contact patch, while the zinc-plated finish helps protect the rotor from corrosion over time. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible with 2005-2008 Pontiac Grand Prix rear brake applications, this rotor set follows OE fitment dimensions for straightforward installation. The AR8287XPR is a practical choice for a Pontiac Grand Prix brake rotor replacement when you want a vented, corrosion-resistant rotor with a performance-oriented surface design.

What It Is Used For

  • Replacing worn rear brake rotors with an OE-fit part.
  • Addressing rotor rust and surface corrosion.
  • Improving heat dissipation during repeated braking.
  • Reducing buildup of dust, gas, and moisture on the rotor face.
  • Restoring smooth braking feel when the original rotors are worn or uneven.

Installation Notes and Tips

Fits 2005-2008 Pontiac Grand Prix, rear. Confirm rotor diameter, bolt pattern, and thickness before installation. The direct OE fit means no special modifications are needed, but the hub and braking surfaces should be cleaned before mounting the new rotors. Use the AR8287XPR part number when verifying application details.

Quality Assurance

Power Stop designs this rotor set as a bolt-on upgrade with OE fitment and corrosion-resistant zinc plating. The AR8287XPR part number is also useful when matching the correct rear rotor application for a Pontiac Grand Prix brake service.
