Yes I have all the driving aids off. I don't know what the simulation tires are, I have: economy, sport, race, dirt and snow.
What I'm talking about on the oversteering is the following. On the rear wheel drives I owned, lastly the Firebird, when I loose grip on the rear wheels in a turn, I accelerate to regain control.
In GT4, you need to brake to regain control. In real life, if I brake I'm up for a fun ride into the ditch.
Moreover, from factory setting, most FR cars will not oversteer when taking a sharp curve with the foot to the floor. Real life counterparts do.
What's what I meant by "funky driving physics".
(I'm doing the missions to drive the Tank ... looks hot)
