Engineered for Australian operating conditions, this Protex Rear Brake Disc Rotor suits Subaru Outback AWD models built from 2019 to 2020. Outside diameter is 280mm with a new thickness of 28mm and a minimum machining thickness of 28mm. The Steel casting is high-carbon enriched for better damping and quieter braking. Vane geometry is matched to the original design so cooling airflow and thermal expansion behave as the factory intended. The casting is fully machined, dynamically balanced and given a protective coating on the hat and edges to slow surface rust. Supplied with a light protective oil film; clean with brake cleaner before fitting. Runout is held under 0.05mm at the mounting face, which prevents the pedal pulsation that follows a poorly machined rotor. Sold new with 12 Months warranty cover and full technical support.
