I have a problem with F 458

[Belphagor]

Hi at all, I have a problem with Ferrari 458, not S1. When I drive the Events Supercar at Silverstone, the car seems on a ice road, is impossible to steer, to accelerate and brake in a good way. I know there is no much room to try a different set, and I've tried many different setup, tire pressure, camber, etc... But for me was impossible to stamp a good time and win the race.
I really appreciate if anyone have some ideas, tricks or a good setup.
Cheers.
Nicola
