All configs are oversteery, or just some ones? For me they drive fine, but I defninitely could increase the overall player experience (plenty of people said the same thing). Me and my "testers" already test driven the new GTone with many improvements (added abs, much more downforce) and it drives great now.
I built a Faux-Nuova around a standard Bolide 350 earlier and it handled much better than the standard Nuova road car.
