Dinan's 395x34mm 2-piece 6-piston Big Brake Kit (BBK) is an ultra-high-end solution for maximum stopping power. Each feature-packed solution is specifically tailored to your vehicle and provides exceptional stopping-power in a wide operating range from daily driving to professional racing. Because of this, the system provides the correct brake bias and integrates seemlessly with the ABS and stability systems which is critical under emergency braking situations. This upgrade handily out-brakes, out-lasts, and out-performs any non-vehicle application specific OEM swap kits, and rivals much more expensive top-tier systems. Whereas most systems on the market either make heavy sacrifices to either look fancy, cut weight, or cut costs, the Dinan system is designed to simply brake better, last longer, and stand the test of time!
