A typical analog pc wheel and pedal set will work will work well.
I recomend also getting a 2way balltop shifter, as trying to shift with the wheel buttons will end up killing you. The game has too many buttons and youll get too confused in the heat of disaster..
Digital gas will not work correctly.
Spyhunters wheel is a great design. Fits your hands perfectly, and allows quick and easy button presses. Its also super durrable - able to take heavy bashes from left to right without harm or calibration issues.
