If thats true that Ferrari insisted on a "good showing" in exchange for supplying future cars to EVO all I can say is some things never change. Typical Ferrari "blue blood" attitude and snobibshness. Just like Enzo pulling out of Monza Coppa Europa Internat'l in 1963 resulting in the race in the race being cancelled to keep Shelby from winning the FIA world championship. Typical Ferrari. You must play their way or they threaten to take their marbles and go home.
The 458 is an amazing car. It should compete on its own merits without help.
