I can do few of them.
-If they is no wheel spin (low power)
-If they don't have too much understeer and if the settings limits even extremes, are able to correct those bad behaviors.
Normally in this game 75% of the FF cars are horribles and are not ables to reach those 2 criteria.
I like the Peugeot RCZ at 550PP , Rebault R4 , Citroen DS is a fantastic car at 450PP , Honda integra '95 also is a good car with nice balance.... some couple of others also. The rest at least i've already tested are craps. In my opinion . If GT had only FF cars , i would stop to play since a long time. No fun at all for me.
Wheel spin is a big problem in GT. At least the physic model representation of this lost of grip. For FF , FR , MR RR cars... all of them.
If the actual lost of grip was reduced to 50% or 25% under the normal grip , this game would be a lot more pleasant game and in my opinion more real .
Drift also have some stupid behaviors because of this.
Just my 2 cts.
