This is the ultimate rear brake upgrade for your Tesla Model S. Our kit utilizes 390mm carbon ceramic rotors and 4 piston monoblock calipers for incredible stopping performance. The carbon ceramic rotors not only last longer than traditional steel rotors, but weigh half as much. Another added benefit of the lower rotating mass from the carbon ceramic rotors is extended range per charge. Custom ZZP top hats adapt these rotors to your existing bolt pattern. The kit comes with everything necessary to complete installation and retain your factory parking brake.
