I've got one on the rear axle my 110 and in normal conditions you don't notice it. However in the snow, or across a muddy field it's been a great improvement with vastly better traction .
hi ive got a pair of quaife diffs in mine v good for traction but when dry if you pull off on a junction with a bit of welly it does torque steer that is why ive got an ascroft locker to put in the front
