It´s not a tuscan speed 12 its just speed 12. What you do have is a tuscan speed 6.
Regarding settings I have a very simple formula:
Race modify the car, then:
Damper bound and rebound lowered to 3
Downforce set on max
This is the essential
Advisable settings also include: 35-40 lsd accel; 35-40 lsd deccel; auto gear set to 21; suspension front 13.0 rear 11.0; ride height front/rear 115.
If you want the car more controlable you can soften the suspension, lower the bound/rebound even more, elevate the car a bit and set the lsd accel and deccel to the max. The ascc and tsc I don´t find very effective but the lsd initial torque can reduce spins and slides.
