Ferrari F2005 - front wheels 'ears' and horizontal disc holes 22 May 2005
A detail change for Monaco - a tiny, wing-like structure inside the top of the front-brake cooling drum. Two horizontal holes (blue arrows) allow air circulation, almost like small air intakes for the brake callipers. As the structure turns with the wheel it also acts as a mobile winglet, providing a small but constant increase in front grip. Its overall width is 12cm, the maximum allowed for brake air intakes. Another change is the holes in the edge of the brake disc, which now run across the edge rather than along it, with each an 'eight' shape rather than oval. These changes improve thermal heat exchange through the disc's side walls.
