Brembo CCM-R (Carbon Ceramic for Racing)

The Brembo CCM-R disc is a product of many years experience accumulated by Brembo in the field of carbon brake materials used in F1, combined with the expertise acquired by the company in CCM applications for road use.

The main advantages of the Brembo CCM-R disc are:
– considerable saving in weight, compared to cast iron (̴ 5kg each wheel assembly);
– high thermal conductivity;
– durability and versatility characteristic of carbon ceramic material for road use (disc life 5 times longer);
– friction 10% better than cast iron (comparison made using the same pad compound);
– operating temperature 5% lower.
Selected materials and original processes, researched and optimized to produce the Brembo CCM-R disc — and incorporating the newest technologies applied to carbon ceramic discs — have resulted in a product with superior engineering features.

Why aren’t seat belts connected directly to the seat?

Seat belts fixed to the seat have some advantages. However, until now, there is no specific FIA standard that regulates the construction of the seat to make it resistant to the loads transferred from the belt in an accident.

The reason why it’s connected to instead to the body, is that the roll-bar is integral to the whole body and it’s able to dissipate impact energy better with a properly designed cage. It’s also able to resist better than a threaded connection built into a body of a composite material. Additionally, until a few years ago it was much easier to simulate the dynamic behavior of metals compared to composite materials, making the predictability in the event of an impact “safer” and the level of protection more reliable.”
