The GR Corolla is a phenomenal track and fast-road weapon, but pushing the heavy GR-FOUR all-wheel-drive chassis to its limits places massive thermal strain on the factory braking components. Upgrading your stopping power is essential to maintain absolute driver confidence lap after lap. Swap out standard materials for high-friction fast road Brake Pads and high-carbon Brake Discs. For serious track enthusiasts, bolt-on multi-piston Big Brake Kits deliver ultimate fade-free deceleration. We also stock Big Brake Kit Replacement Parts (Rotor Rings and BBK Pads) to keep your high-end setup fresh. Firm up your pedal feel and completely eliminate sponginess with braided stainless steel Brake Lines and high-boiling-point performance Brake Fluid.
