ride height issue off on one side
So I was looking at my BMW today in the garage (relatively flat surface) and noticed that the height on the passenger side is about 1 1/4 inch higher than the drivers side and it is on a noticeable slant. I used a measuring tape to check the heights on both side form the ground to the wheel well. What could be the issue here, maybe just needs a simple calibration? I had installed new tires and did a 4 wheel alignment a few weeks back..something could have got thrown off? Thanks!
