Ferrari 150° Italia - modified rear wing 10 September 2011
In Monza Fernando Alonso and Felipe Massa have been using the new rear wing Ferrari introduced at the last round at Spa. But there are some differences on the Monza-spec wing (see main drawing), including different endplates with just two gills instead of three (see upper red arrow and inset) and a lower downforce main profile and flap. The beam wing (see lower red arrow) is also new. No longer straight in shape, it's wider at its centre and has a different chord. In order to produce more downforce and better preserve their tyres, Ferrari used slightly different incidence angles on the rear wing for qualifying and race compared to practice.
