yeah mine sits level in the front it's just the rear thats 10mm higher on the LH side, i just had a closer look at the spring set up and the seats at the bottom are opposite, the springs start in different places and the seats are angled forward abit i think, so this would cause the springs to be seated at different heights, this was the only thing i could conclude on causing this height difference as everything else is perfect, what do u guys reckon?
