Diffuser stalling?
Something quite annoying which occurs in Class A, GT3 and GT1 cars for me is out of the box, they all seem to suffer from massive oversteer in places where they're going at high speed through aggressive elevation changes (Riviera, Eau Rouge @ Spa, etc.). What I'm assuming is going on is the car is being pressed flat against the ground by this vertical acceleration and downforce combined, thus preventing any air from flowing through the diffuser, and reducing the downforce on the rear wheels. Sometimes, I spin out from this, sometimes I just drift off line and lose a position.

It seems fair to have to compensate for this with setup in the GT3 and GT1 cars, but in a car like the MP4-12C which has far more ground clearance (to handle speedbumps), is this really correct behavior? As this seems like a serious fault in the car if so for a track day at a circuit like Spa.
