With Circuit de Gilles Villeneuve being particularly hard on the brakes, all teams have modified their braking systems to cope with the additional demand. On a full lap, the cars are for 16% of the time under braking, more than any other track on the calendar.
Renault for instance clearly increased the brake duct aperture, catching more air to provide more cooling to the brake discs and pads (notice the difference with the Turkish configuration in the inset). Renault also ran a new front wing, removing the stacked elements of the wing. The rear wing was also modified, retaining the unique W-shape, but extending its curves and reducing the frontal surface of the wing.
