Ferrari F2007 - brake duct blanking 17 September 2007
A subtle but interesting change at Spa was the F2007's partially blanked-off front brake ducts. Rather than using the usual sealing tape to achieve this, an actual lip (inset - in blue) has been added to the internal vertical edge of the duct, so as to better manage airflow through the reduced duct entrance. The smaller entrance is made possible by the relatively low air temperatures in Belgium. So why not simply use smaller ducts? Because this solution is better at moderating the airflow in relation to the car's speed, which varies greatly between the fastest and slowest parts of the Spa-Francorchamps lap.
