The Driving Force is the one without the foot pedals and has flappy paddle style levers, which are easy to configure in GT to throttle and brake. The Force feedback is very nice and strong, settings go from 0 to 10 and it feels well built for the cash, unlike that horrible horrible Trust wheel i tried a couple of weeks back, The LDF has true 1:1 movement and the slightest turn is translated onto your screen wheel. nice.
Mine, once set up was strangely about 15' off true clockwise, but upon removing the base cover i saw what needed to be done. i marked the gearing with a pen at the point the wheel thought was true, then moved it around to where i wanted it and marked the gear again. i then set it back to the first mark and carefully disconnected a mini connector off the motor, moved teh wheel back 15' anticlockwise and replaced the connector. job done.
I've also, already, covered the center boss with carbon wrap, because thats the sort of thing i have laying around this place! :)
oh, and footstool and bungee cords not included in the box, but give a great firm base and bring the wheel upto the right height when leaning back against the sofa.
