500 or more hp, VCD at 30% (There's no point if you put it to 10%, May as well get an Fr car..) Or better yet, get rid of the VCD , It messes with the system the GTR has altogether.. Are you running sims?
I use between a 35% and 50% setting... 10% is too much like a FR... Also, I find you can achieve much higher angles, without the use of countersteer, if your VCD is set to a more balanced setting...
