Rear winglet addition for increased downforce

As with any other team at Monaco, McLaren have sought for solutions to increase downforce with a minimal drag penalty. They have come up with an extra winglet fixed in between the central rear wing supports. The new item simply doesn't stretch the whole rear wing because of the technical regulations. Due to its small size, it will only add a tiny bit of downforce to the rear end of the car while not adding too much drag. In fact the winglet will cooperate with the rear wing just above it and hence offsetting the drag generated if you would test the element alone in a windtunnel.
