The 991 GT3 RS features motorsport-derived braking architecture capable of hauling the widebody chassis down from speeds nearing 200 mph. However, aggressive circuit driving places immense thermal stress on the factory friction materials, even if equipped with Porsche Ceramic Composite Brakes. Upgrading to high-carbon slotted or cross-drilled Brake Discs combined with high-temperature Brake Pads ensures repeatable deceleration and mitigates thermal fade for cast iron setups. To eliminate pedal deflection, replacing standard rubber hoses with braided Brake Lines and flushing the hydraulic system with high-boiling-point Brake Fluid provides a consistent pedal feel under heavy braking. We also supply Misc Brake Parts for calliper maintenance and track preparation.
