Just for some information, finally got a reply from BMW Australia and their reply was that all their RHD cars will be lower on the right suspension due to the car being designed for LHD and fuel + battery weight making the car lower on the drivers side here in RHD land. Suspension is unadjustable also. Up to a 3cm drop is acceptable.
Well that was a disappointing result, seeing as how the average Aussie male weighs around 130kg, the drop is unacceptable imo.
Going to go and see a suspension mechanic to see if they can raise the car to be level again.
