+ I now convince you. + (Or are the crosses baptise you)
I see your a wheel user so yes use manual gears, look at the torque curve in options you'll see this car has a very flat torque output so you have a very wide gear changing range.
Main thing with these cars FF in the "Game" is timing when to go full gas, to soon you'll hear the front wheels spin up, it will pull you wide and then you have to lift. So you have to play the waiting game before you hit the gas pedal.
It has good grip so you can afford to brake light into most corners then just keep a little gas on to maintain good momentum through the apex. Now here comes the waiting game, time your full gas so you "do not" have to lift at the same time get your steering wheel as straight as possible this will help with grip (stopping the wheels spinning up) then you'll get good grip out of the corners.
Hope some of this helps.
