My impression of the GT3 is that the complete physics was more or less fiddled together without any real basis. Before the current bop, for example, the Aston Martin was a disaster where the standard setup already required the highest spring rates in the front and the lowest in the rear so that the car does not constantly break out with the rear. Now they have introduced softer springs in the rear with the bop, which makes it better, but it shows there is more try and error than really using a healthy base, as the current Audi R8 shows, because it is even worse than the Aston Martin before. No idea how you can make a bop on this basis at all, if you have to bend the setup again to the limit, so that the car becomes drivable at all. If you then still see how the wheels drag on the body of the Corvette, you also know that the data of wheelbase are rather dubious, in the M6 was the rear axle more than a year completely out of place and the rebound of the dampers had virtually no function. I quickly noticed the differences in the brakes, too. You can hardly get the Aston Martin to lock without ABS, for example, but other vehicles very easily. Either the braking force is so different or the grip level but no matter what it is, one may doubt a halfway reasonable implementation of the driving physics.
