The GR86 is a phenomenal, lightweight track weapon out of the box, but pushing the ZN8/ZD8 chassis to its limits places massive thermal strain on the standard 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, or choose our convenient Brake Disc & Pad Combo Packages for a complete, hassle-free front and rear overhaul. For serious track enthusiasts, bolt-on multi-piston Big Brake Kits deliver ultimate fade-free deceleration. We also supply 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.
