Power Stop AR83109XR Evolution Drilled & Slotted Front Brake Rotor - Right

The Power Stop AR83109XR is a right/passenger-side front brake rotor from Power Stop's popular Evolution Drilled & Slotted performance line. Engineered as a direct bolt-on upgrade over stock rotors, this rotor delivers improved stopping power, cooling, and longevity for street and light track use — with no special modifications required.

Key Features:

• Cross-Drilled Holes: Precision-drilled and chamfered to maximize rotor cooling during extreme braking conditions, helping resist brake fade
• Rounded Slots: Beveled slots sweep away gas, dust, and moisture, maintaining a clean friction contact patch for smooth, consistent braking
• G3000 Grade Cast Iron: Sourced from premium foundries with a higher carbon content for superior hardness and durability
• Silver Zinc Dichromate Plating: Full-surface zinc coating protects against rust and corrosion, maintaining a clean appearance behind open wheels
• 100% Mill Balanced: Each rotor is individually checked and balanced for vibration-free, smooth braking performance
• Direct OE Fit: Matches factory vane count and dimensions for a straightforward, tool-standard installation
• Right/Passenger Side: Sold individually — pairs with AR83109XL (left side); available as a pair under AR83109XPR

The Power Stop Evolution drilled and slotted rotor is the brand's most popular performance upgrade for daily drivers and enthusiasts seeking improved braking performance on the street or occasional track day. The AR83109XR is the right-side rotor designed for use with stock calipers.
