The new fixed caliper is available in 17-inch (5.9 kilograms), 18-inch (7.7 kilograms) and 19-inch (8 kilograms) versions, is designed for cars using a “high braking disc surface.” Big ass brakes disks is what I think they are trying to say. They also kindly point out hat big ass brake disks “usually require generously-sized calipers, which entails an increase in weight.”
So Brembo spent more than 100,000 development hours to come up with this:
The distinctive feature of this caliper is the new shape, centered on five openings: two at the front, between 16 and 22 cm2, and three on the bridges, with an area between 7 and 11 cm2.
This solution, patented by Brembo, ensures a mass reduction of nearly 8 percent with additional mass savings in material at the points in the caliper with least stress. Such a significant weight reduction in the unsprung mass of the vehicle contributes to savings in fuel consumption and pollutant emissions.
Through a co-design approach with each OEM customer, Brembo will be implementing solutions specifically tailored to individual car models in order to complement each manufacturer’s different design style. Which I think means Porsche and Lambo logos instead of the Brembo. Either way they look cool and they do look lighter even if most of us will never notice the difference.
