another thing i've noticed is the FFB, i was playing GPL & F12002 and the moment your about to lose traction, the steering becomes lighter thus allowing you back out of the throttle or down shift and sort out the car.
this is missing from gp4, and the fact that if you downshift really fast the car does'nt spin out, this is wrong too, a example of this as hakkinen at monza 98
