These rotors with hats only weigh 5.4 lbs and come with 4 pistons. Everything is included in this kit for easy installation. By simply bolting on a ZMI brake system, you will experience superior stopping power, as well as, faster acceleration and more responsive handling. Never before has a company been able to offer better acceleration and improved handling with only changing the brakes on your street vehicle, until now. With weight reductions of both the rotor and the caliper, we can greatly reduce the amount of un-sprung weight on your vehicle. When you reduce the amount of un-sprung your vehicle will respond quicker and handle better. There is less weight for your suspension to move up and down, less weight = faster reaction times.
