i want to buy the steering wheel and pedals but i want to know if the clutch even works
What isn't perfect is that you have to completely off-throttle as well which isn't 100% necessary in a real car (that isn't yours)
Just remember at the start of the race you have to press the triangle button as that is the toggle clutch on/off button. On a GT25/27 the triangle button is the upper most black button on the shifter piece.
