EBC RK903 RK Series Premium OE-Style Replacement Disc Brake Rotor Set

The EBC RK903 is a premium OE-quality replacement disc brake rotor set engineered to the exact same specifications as the original factory parts. Cast from G3000 grey iron — the same high-grade material used by original equipment manufacturers — these rotors deliver reliable, consistent braking performance that matches or exceeds factory standards.

Key Features:

• G3000 Grey Iron Construction: Cast to a material strength of 150 N/m² with a tightly controlled surface hardness variation of less than 20 HB for long-lasting durability
• Precision CNC Machined: Machined to a surface tolerance of less than 0.05 mm for optimal pad contact and smooth, vibration-free braking
• 100% One-by-One Runout Inspected: Every rotor is individually inspected to guarantee zero distortion straight out of the box
• Thermic Corrosion-Resistant Coating: Black Thermic coating provides an attractive finish while protecting against rust and corrosion
• Vented Design: OEM-spec vented rotor construction for effective heat dissipation during normal street driving
• Balanced Construction: Precision balanced to eliminate vibration and ensure smooth pedal feel
• Sold as a Pair: Includes two rear rotors for a complete axle replacement

Over 80% of EBC brake rotors sold in the USA are British made, and all casting suppliers are ISO approved and have been certified by the German TÜV authorities. The EBC RK903 is the ideal solution for drivers seeking a direct-fit, factory-quality replacement rotor with superior quality controls. Cross-reference part numbers: EBC-GD903, EBC-USR903, EBC-BSD903.
