Our 09D Replacement Brake Rotors are precision-engineered, high-performance discs designed for use with our 09D big brake kits, offering uncompromised stopping power, thermal control, and durability for both road and track use. Sold as a matched pair, these rotors are manufactured from FC25 carbon steel, a premium-grade material renowned for its excellent thermal stability, strength, and resistance to distortion under extreme braking loads. Each disc is blackened for corrosion resistance and enhanced heat dissipation, combining performance with long-term durability. Information Our rotors feature a distinctive, motorsport-inspired groove pattern, developed through extensive testing to:- Maximise debris and gas evacuation during braking- Maintain a clean pad surface for optimal bite and consistent pedal feel- Prevent glazing and reduce the risk of fade during sustained high-temperature use- Enhance initial bite and braking modulation under both light and heavy pedal inputs This groove design not only promotes strong, consistent braking performance, but also contributes to longer pad and disc life by reducing heat buildup and surface contamination. Features FC25 Carbon Steel Construction – Offers exceptional heat resistance and structural integrity, ideal for high-stress, repeated braking events. Blackened Finish – Assists with corrosion resistanceand promotes even heat distribution. Floating Disc Compatibility – Designed to mount onto your existing 09D disc bell using our bobbin system, ensuring controlled thermal expansion and eliminating rotor warping. Sold as a Precision-Matched Pair – Ensures even brake balance and wear across both sides of the vehicle. Fitment Suitable for use with the following 09D Big Brake Kits - FBR019AA (Focus ST Mk4/4.5) / 909FBR019AA (Focus ST Mk4/4.5). What's in the box 2x BBK Replacement Rotors
