The BMW M135 delivers sharp, explosive performance, but pushing the B48-powered updated UKL2 chassis to its limits places immense thermal strain on the factory braking system. Upgrading your stopping power is essential to maintain absolute driver confidence on fast-road drives or track days. Upgrade your setup with Performance/Upgraded pads and fast road Brake Pads paired with high-carbon Brake Discs for improved initial bite and thermal management. For ultimate stopping power, bolt-on multi-piston Big Brake Kits deliver fade-free deceleration, supported by our stock of BBK replacement parts (discs and pads) to keep your calipers performing perfectly. Firm up your pedal feel and eliminate sponginess with braided stainless steel Brake Lines and high-boiling-point performance Brake Fluid.
