It all has to do with engine torque, Moze. It's not the fault of the LSD. Thats just the direction the engine twists the frame when its building torque.

DER DER DER Moze. Ever notice the cars or trucks at the track where the left front tire in in the air and not the right front? Ok, think about it Mozey, in which direction (sitting in the drivers seat) does the motor rotate? Then think about where that resultant rotated energy is projected... Speaking in structural terms (this is where I get to use my retardedly long 6 year degree), the torsional energy from the driveshaft is transferred to the LSD which is the moment connection form the torsional energy. The resulting tensile force (sometimes known as shear force--which eats up G80's) is then transferred to the axle shafts, which makes your tires go around and around. When the ring gear gets the torsion forces from the driveshaft, it hits the carrier--and yes, an LSD would mean (upon the correct amount of applied forces) that both tires would spin, with the moment energy being applied in a clockwise direction, the right rear tire is going to be doing most of the work, as described by Quik and Greg.
