FIA GT F430 GTC & 997 GT3-RSR

[RaceLM24]

Hello,

Can anyone tell me what the best physics for the FIA GT championship of the Ferrari auto F430 GTC and Porsche 997 GT3-RSR? Of course that they use the same model as tires.

I tried many mods but I can't find a fair balance between the two models. In all F430 they are always clearly higher than 997 and you can't get a balanced championship in the 2008 and 2009 seasons in the GT2 category, as it was actually.

Thanks as always for your advice!
