I did some FR tuning last night, but it's very early for me on this front. I have the Ferrari and want to go after setting it up. Don't have the game available right now.
I would try these approaches, directionally.
Ride Height - Front even with or potentially slightly higher than rear.
Stiffen rear ARB relative to front
Stiffen Rear Springs and/or soften front springs
Same with Dampers
Camber, I would use a range of 1.0-2.0 in both front and rear, try different combinations to balance the car.
Toe, I would zero the front and then set rear anywhere between -0.10 to +0.10. Try different settings and see the effect they have.
LSD is going to be very important, ride height and LSD will get you a good portion of the way there.
I was running 20/45/15 on the Corvette C7 Gr.3 list night to have it at a point of manageable.
