Stock rear rotors on the Focus RS MK3 were sized for street compliance, not the repeated high-heat cycles that come with track days and spirited driving. The EBC Racing SG2031 SG Series rotors give the rear axle a proper one-piece replacement that sheds heat faster and keeps braking consistent lap after lap.
SG Series compound matched to the rear axle. EBC Racing specifies the SG Series compound for rear fitment, balancing bite and modulation to work with the factory brake bias on the MK3 Focus RS. The result is progressive, controllable stopping power rather than abrupt lock-up.
One-piece rotor construction. A single-piece design keeps the rotor rigid under thermal load, reducing the flex and vibration that can introduce pedal pulsation during sustained braking. The set covers both rear positions, so the braking system remains balanced side to side.
Direct fitment for the 2016-2018 Focus RS MK3. These rotors drop into the rear caliper bracket without modification. No adapters, no drilling, no re-machining of the hat or mounting face.
Product Benefits
- SG Series Compound: Engineered for the rear axle of the MK3 Focus RS to maintain balanced braking bias.
