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.
