McLaren MP4-30 / Ferrari SF15-T - vented brake drums

Monaco’s famous street circuit is very hard on brakes, hence keeping them cool is essential.

McLaren have been using the brake drums above with oval holes since the start of the season and in Monte Carlo Ferrari have adopted a similar solution on Sebastian Vettel’s car. In the drawing of the SF15-T below the round brake drum - or ‘cake tin’ as it is commonly known - is missing, allowing you to see the oval openings that have been added in front of the brake disc.
