Greyoutjust an FYI, most hardcore drift setups are modified to have a much quicker steering ratio, so the 900 degree mode does not accurately simulate D1 style drifto-whatever driving.
Thats true, but in GT4P each car has different steering ratios. So if a geniuine D1 car was in GT4 it would presumably also have the quicker steering ratio like the race cars do.
