Hakkinen.... here are the things that you should have:
855bhp
605kg at least
no editting of phisics (that means no more than 100% grip)
you can have that with the original GP4.... or with some GPxPatch installed, with the pshisics unchecked!!!!
The carsetup is very important by the way.... and don´t be scared for being much slower than the top guys.... that happens on the first time... watch some guys laps (Silverstone is not so good to watch, get some Montreal hotlaps for example), and compare it to your own performance, then you will find out where you loose or gain time!!!!
feel free to ask anything you want mate!!!!
