Six ventilation options for Formula 1
Depending on the temperatures forecasted for the Grand Prix, and the specific race strategy, each driver can choose from six different Brembo front disc solutions. There's the medium cooling option with 800 holes, high cooling with 1,250 holes, and very high cooling with 1,480 holes; each of these then offers a sub-option with a process on the outer diameter - the so-called “groove”.
In the case of very high cooling, the holes are arranged on 7 rows, with 6 rows for the intermediate option and 4 for the lowest level. The holes are 2.5 millimeters in diameter, and are made one at a time by a precision machine; it takes 12-14 hours to make all the holes on a single disc. The mechanical component tolerance is only four hundredths.
