Ferrari 248 F1 - brake cooling drums 19 March 2006

This interesting feature used in Malaysia is an evolution of similar devices seen on cars last year, but Ferrari have taken it to its extreme. The cooling drum not only covers the brake disc and calliper, preventing heat being transferred to the wheel rim, it also creates a seal of sorts with the wheel itself. It completely fills the space inside the wheel rim, not only improving brake cooling, but also dramatically reducing the vortices generated by the rotation of the wheels, hence making this area more aerodynamically efficient.
