PowerStop AR8161SCR Disc Brake Rotor - Front

Overview

PowerStop AR8161SCR is a coated disc brake rotor built as a direct bolt-on replacement for the original equipment part. It is engineered for the front brake position on select Ford Focus applications and uses a corrosion-resistant finish on the hat, outer edge, and vanes to help preserve appearance behind alloy wheels.

This vented, full cast rotor is mill balanced and built to match original equipment weight and vane count for proper fitment. The AR8161SCR is a practical choice for drivers replacing a worn front brake rotor on a Ford Focus while keeping OE-style dimensions and performance characteristics.

Key Features

• Direct bolt-on replacement for original equipment fitment
• Silver epoxy coating on corrosion-prone areas
• Vented rotor design for consistent brake cooling
• Full cast construction with mill balancing
• Smooth surface finish and OE-style specifications

Detailed Description

PowerStop’s coated hat and edge rotor line focuses on OE-style replacement parts with added corrosion protection. This rotor uses a partially coated design that covers the hat, outer edge, and vanes, helping reduce rust on exposed surfaces while maintaining a clean look behind modern wheels. The AR8161SCR also follows original equipment weight and vane count targets, which supports proper fitment and consistent brake system operation.

Compatible With 2000-2004 Ford Focus, front brake applications, this rotor is sized at 258 mm outside diameter with a 22 mm nominal thickness and 20 mm discard thickness. The 4.25-inch bolt circle and 4-lug pattern align with the specified application. This part cross-references Monroe Shocks & Struts (e.g., 3S4Z 1125-AA, 7S6Z1125B) for the same application.

Common Replacement Reasons

• Brake pulsation from rotor wear or thickness variation
• Visible rust on the hat, edge, or vane area
• Reduced braking consistency from a worn rotor surface
• Need for an OE-style front brake rotor replacement
• Rotor replacement during a brake service on a Ford Focus

Installation Notes

Install as a direct replacement for the specified front brake application. Verify rotor dimensions, bolt pattern, and brake hardware condition before installation. Clean the hub mounting surface and confirm the rotor seats flat to help prevent runout-related issues.

Quality Assurance

PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for confirmed fitment on the listed application.
