When I got my car, a 1600 Junior, but with a 2L engine, it had the 4.55 non-LSD axle. It was fun, but the ratio did seem to short for the motorway and it would go up through the gears like a demented puppy.
When I had a half shaft break, I took the opportunity to upgrade to a 4.1 LSD axle. The LSD is great - no more sitting spinning one wheel at junctions. The longer gearing has changed the character of the car - more grown up, better on the motorway, but still fun on the back rounds. The change even brought the speedometer closer to reality
I can see why some think the 4.3 is the optimum
