Evolution Performance Rear Brake Rotor Pair

The PowerStop AR8643XPR brake rotor pair is engineered as a direct bolt-on upgrade for enhanced braking performance and cooling. Precision cross-drilled holes are chamfered to minimize stress cracking, while rounded slots effectively sweep away exhaust gases, dust, and moisture, maintaining optimal rotor surface condition. This design contributes to maximum cooling and peak performance, especially under demanding driving conditions. Constructed from cast iron, these rotors feature a silver zinc dichromate plating for superior rust and corrosion resistance, ensuring longevity and maintaining a clean appearance. Manufactured to strict tolerances for disc thickness variation (DTV) and runout, they provide a smooth, quiet braking experience that meets or exceeds stock performance. Key specifications include a 330 mm outside diameter, 85.90 mm overall height, and 1.04-inch discard thickness. The rotors are vented for optimal heat dissipation. These are performance-grade, full-cast iron rotors with a cross-drilled and slotted surface type. Note that the ABS tone ring is not included with this rotor pair.
