Some (a lot) questions about FXX

Hi to everybody

I'm creating an FXX mod for Geoff Crammond's GrandPrix 4 and I need some information and photos:

photos
- a photo of wet-tyre tread
- a photo of tyre's side (I'm interested in codes)
- a photo of the steering wheel (if it's perpendicular to the steering wheel, it's perfect)
engine
-is it true that the fxx has 690 Nm at 5750 rpm, the top speed is 390 Km/h (limited at 345) ?

and now the most difficult thing to reproduce in the game...
car behaviour (I'm italian, the Fxx owner is italian, I think it's better if he wrote these thinks in italian; the translation from italian to english and back from english to italian is not the better to describe the car behaviour)
please tell me about engine, brakes, tyres consumption, etc...


many thanks in advance and sorry for my english
