Nikaz my car dont handle like thati cant get under 1.45 and it just understeers like a biatch on the last segment .
Dunno what im doing wrong but there is now way i can go that quick tbh .
Is the official patch out yet or are you still running vanilla v1?
Persil
I'm running vanilla. I'm not sure what I can recommend regarding grip levels apart from posting the 'Driving' settings I've adopted:

At first try setting Traction Control to Low. Waste a few laps attacking every bend, don't concern yourself with making the following corner at first. the point is to prove how much grip this car has, seriously it's got loads.
e.g. Stowe corner, the one at the end of Hanger Straight. Brake hard well into the red about two car lengths I'd say whilst dropping to third, off the brake. As soon as your off the brake immediately turn in hard & max the gas ALL IN ONE MOVEMENT. It will grip. On exit upto fourth running the curb. Stay in fourth drop to second for the next sequence Vale.
inam22 you're on xbox right? How are the grip levels compared to mine?
