Don't want to side-track this thread too much but as long as you're talking lockers I've got a quick question. How much difference would a rear locker make if we've already got limited slip? The left:right torque split with a locker is always 50:50 - i.e., if one tire has no traction the other is still getting half the torque right? So what is the torque split with a LSD if one tire has no traction?
