• Precision mill-balanced: 100% mill-balanced for smoother stopping and low vibration at any speed.
• Premium iron castings: built with high-carbon alloy, G3000/G11H18 iron castings for strength, stability, and durability.
• Geomet® coated: high-performance corrosion protection.
• OE vane configuration: matches the original equipment vane configuration for proper heat dissipation.

A fine-turned finish (16 RMS) supports faster initial rotor-and-pad break-in, while tight tolerances hold disc thickness variation to 0.010 mm and lateral runout to 0.050 mm maximum. This is a rear-axle rotor, sold individually — order two and replace both sides as a matched pair for even, balanced braking. If worn or warped rotors are behind your brake pulsation or vibration, this drops in to replace one of them on the listed applications.
