PowerStop AR8111XPR Disc Brake Rotor Set - Front

Overview

PowerStop AR8111XPR is a drilled and slotted disc brake rotor set built as a direct OE-fit upgrade for select Ford and Mercury applications. It combines vented construction, cross-drilled holes, and rounded slots to support cooler, cleaner rotor surfaces under demanding braking.

Compatible with Ford Mustang front brake rotor applications from 1979 and 1982-1993, as well as Ford Thunderbird front brake rotor applications from 1983-1988 and Mercury Cougar front brake rotor applications from 1982-1988. The AR8111XPR is a practical choice when you want a direct-fit replacement with added surface treatment and corrosion resistance.

Key Features

• Drilled and slotted surface helps move gases, dust, and moisture away from the friction area.
• Vented rotor design supports heat dissipation during repeated braking.
• Silver zinc dichromate coating resists rust and corrosion.
• Direct OE fit reduces the need for special modifications.
• Built for front brake rotor applications with a 4-lug bolt pattern.

Detailed Description

PowerStop AR8111XPR uses a slotted X-drilled design to improve airflow across the rotor face and maintain a cleaner contact patch. The vented construction, 10.10-inch outside diameter, and 4.30-inch bolt circle make it a fitment-specific replacement for older Ford Mustang, Ford Thunderbird, and Mercury Cougar front brake systems. The AR8111XPR is intended for buyers who want a rotor that matches OE fitment while adding a performance-oriented surface design and corrosion-resistant finish.

This part cross-references PowerStop (e.g., AR8111XPR) for the same application.

What It Is Used For

• Brake fade caused by heat buildup during repeated stops.
• Surface contamination from dust, gas, and moisture on the rotor face.
• Rust and corrosion on exposed rotor surfaces.
• Replacing worn front rotors with a direct-fit option.
• Maintaining consistent friction contact during braking.

Installation Notes and Tips

Verify rotor dimensions, bolt circle, and front fitment before installation. This rotor is a direct OE-fit replacement, so no special modifications are needed when used on the listed applications. Inspect pads, calipers, and hub surfaces during service to help ensure even contact and proper braking performance.

Quality Assurance

PowerStop designs this rotor as a bolt-on upgrade with OE fitment and a rust-resistant coating for dependable service in demanding braking conditions.
