Lets go!

Car Class: S 930
Power: 489 HP / 360kw
Torque: 343 Lb-Ft / 465 Nm

Desciption:
It's a lovely Car. But be careful. If you drive too agressive you will take bad Laptimes. If you are good to your Car it is good to you
I've tried the F430 with this Setup on Silverstone and i got a 1:49.836 in 5 Laps... so you see a very nice competitive Car.
