The PowerStop semi-coated rear brake rotor for 2013–2018 BMW 320i xDrive is a direct bolt-on replacement that preserves OEM braking behavior while adding corrosion resistance. A silver epoxy coating protects the hat, outer edge and vanes to maintain appearance behind alloy wheels. Built to match original weight and vane count for guaranteed fitment, it includes cross-hatched friction faces for pad break-in, precise DTV/runout control and dynamic balancing; sold individually.
