I've seen several pictures of people that have a clutch pedal for their sim racing setup. I've noticed that I dont see a 2nd wheel anywhere so my question is this. Is there a single pedal that I could buy to just hook up to my PC? or as it seems many sawed a pedal set in half and stuck it next to the other set of pedals and the wire goes off picture. I'm not quite sure wether they just hook it up to a PC or need a 2nd wheel that hooks up to the PC also.
