I'm using a T300 and the clutch pedal works on my set up.
I don't have a shifter attached to the wheel but the clutch works along with the paddles.
In a odd way, I have a clutch working system that disengages the drive to the car but instead of working a shift stick, the paddles work as my stick.
Basically, the paddles are my stick shift.
So, I have the choice of auto-box, paddle shifting and clutch shifting.
Hope that made sense, kind of hard to explain LOL
