Get a proper LSD :D
I've not checked 0-60 as I'm not interested but the acceleration with the combo of supercharger, lightweight clutch/flywheel, sorted suspension, sticky tyres and the biggest difference a proper 1.5 way LSD is miles better than without. I'm going to do a few passes in Santa pod one of this days to find out the improvements over stock. But it feels between 4.2-4.8secs butt dyno
