Besides the F1 cars which IHMO shouldn't be in the game because they make the game too easy , you can get great times with the ZZII because of its 4WD , also the lighter cars (even when they have less hp) with nice set gears (you have to play around a little with settings) also especially when driving high powered rwd cars , don't forget your supersoft slicks to get the grip in the quickest time , also i think a steering wheel (yeah!) is a good thing for 0-400 0-1000 and other dead stops that matter because you can give little gas for the very start to get the car rolling and then push it good , i often get better times when even not reving the 1st gear all the way up , of course if you drive with all of the assists off and Mt , otherwise in my opinion you're no real Gt3 players...
