I tried almost every setting on that car but once you upgrade the power it will just spin and spin. My only advice is to sell it (if youre having the same problem i have) and just re-buy it and not upgrade the motor as much.
FWD cars have a power limit of 200-250hp. Once traction is an issue you have to be able to anticipate understeer and start your turn in very early, done properly, you can actually drift the front of the car and still make the apex.
New spoiler? Unless it comes with a fully functional one I suggest you get one and put downforce on the car as hard as you can... Worked for my TVR Cerberus that just spinned its wheels like mad... Now it has more grip on the road, thus less tire spins... Might work for a FF cause you can control the front downforce as well... (Well if thats not the issue... It's an FF!! it has limits!!)
