Having a discussion with a friend the other evening about our respective cars, and we got onto the subject of differentials. Mine has an aftermarket Quaife automatic torque biasing diff, and his has a factory clutch type LSD. We both wanted to argue that our respective systems was better, but both lacked sufficient knowledge in the area to come to an informed decision. Anyone want to shed some light on which is the better system? The cars in question are FWD.
