lol.......... not convinced..but sum good statements..... the grip level is the level that you get .....90 persent is less than the grip level that you get so ...not realistic....gtr2 a very good sim ...u carnt change the grip level i live 20klm from zandvoort i now about the sand ......on a dry day when your tyres are up to temp the grip shouldnt be set by anything but the game.....after all i recon cunos are good at wot they do and if they thought the sim had to much grip they wouid call 90 ...100 so..
