Dinan's 395x34mm (6-Piston) and 370x32mm (4-Piston) 2-piece Big Brake Kits (BBK) are 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 seamlessly with the ABS and stability systems which is critical under emergency braking situations. This upgrade handily out-brakes, out-lasts, and out-performs any OEM brake system iteration, 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!
