The DFC 900 Series is a high-carbon alloy front brake rotor engineered for quieter operation and added thermal capacity, finished with a GEOMET coating for high-performance corrosion protection. A fine-turned 16 RMS surface speeds initial rotor and pad break-in, while the casting is held to a maximum 0.010 mm disc thickness variation and 0.050 mm lateral runout for true, smooth braking.
