it might not be true, but i always just assume laguna is modeled as if there is sand all over the track, which is why you always seem to have less grip than on other tracks, even in the same car. I pretty much just loosen the car up, and tweak it to let it rotate easier. Negative rear toe, less lsd initial/deaccel, maybe a tiny bit more accel. I raise ride height for the corkscrew and if you can, tweak downforce to even the balance.
