The DFC Geomet-coated left-rear rotor for 2017–2025 BMW 430i xDrive Gran Coupe is a hi-carbon alloy replacement that restores braking performance and resists corrosion. Manufactured from premium G3000/G11H18 iron castings and OE-style vanes to aid heat dissipation, it’s precision mill-balanced and fine-turned (16 RMS) to minimize vibration and improve pad break-in. Geomet coating protects the surface; DTV ≤0.10 mm and lateral runout ≤0.50 mm ensure dependable stopping.
