what is reduced unsprung weight?? this is a description from the ceramic brakes:
one of the major benefits of ceramic brakes is reduced unsprung weight. on the porsche gt3, ceramic brakes are a $7500 option. they reduce unsprung weight by 27kg's over the standard brakes. that's close to 60 pounds!

well yeah hehe.. that's a racing brake setup though.
13.8"(350mm) rotor size front AND rear. 4pot brembo calipers

<i>At Porsche, we're committed to developing the very best in performance engineering. An integral part of that concept is brake technology. Which is why the 911 GT2 comes with the most effective braking system ever featured on a production Porsche: the Porsche Ceramic Composite Brake (PCCB) - a powerful new technology designed to cope with even the most extreme conditions on racetrack and road.
At the heart of the new technology is a ceramic brake disc made of specially treated carbon fibre silicated in a high-vacuum process at approximately 1,700 ēC. The PCCB disc is cross-drilled and internally vented, and is approximately 50% lighter than conventional alternatives. Since this weight is unsprung, i.e., not supported by the suspension, PCCB automatically improves agility and handling. Another feature of the system is the innovative new composite brake pad, which combines with the ceramic disc to deliver extremely high and constant levels of friction under braking. By replacing conventional metal components with composite pads and discs, temperature is no longer a factor in brake performance. This configuration not only helps minimise braking distances - particularly under heavy use - it also ensures safer deceleration from high speed thanks to improved fade resistance.
In an emergency stop, PCCB immediately delivers maximum stopping power to the road. Abrasion is extremely low compared with metal discs, with each PCCB disc offering a service life of approximately 300,000 km. The new composite brake pads also last around twice as long as conventional ones. What's more, the new PCCB pads do not absorb water, making for outstanding performance in the wet. </i>
