The 991 GT3 features motorsport-derived braking architecture capable of hauling the rear-engine chassis down from speeds nearing 200 mph. However, aggressive circuit driving places immense thermal stress on the factory friction materials. Upgrading to high-carbon slotted or cross-drilled Brake Discs combined with high-temperature Brake Pads ensures repeatable deceleration and mitigates thermal fade. 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.
