How level is your rear???

Nothing homosexual here. After lots of fannying around with my car at BMW they finally replaced my rear springs which seems to have corrected the fact that one side was higher than the other (probably an inch between each side). That said there is still a small (less than the 10mm allowable by BMW) difference with the drivers side being higher. With that in mind and my OCD can I ask how everyone else's rear is. The measurement is taken from the bottom of the alloy wheel (not the tyre) to the top of the arch. Obviously it has to be measured whilst on level ground. Possibly with me sat inside the difference would be reduced. Hmmm must try that

My car is on OEM suspension on the rear and adjustable top mounts front.

Is everyone's sitting perfectly level and equal each side????

Top of the rim to the underside of the arch is a good indicator, but not foolproof.
The car would need to be on level ground, as you mentioned, both rear tyres would have to be the same in good order and inflated to the correct pressure in both. Then you stand a chance of having it level.
If however the measurements do not correspond then it could be indicating that the spring on the lower side is suffering fatigue and would need changing also. (always in pairs) Hope this helps

When you have done all your measuring, measure from the floor to the jacking point on each side and see if the difference is the same as the difference to the arch, thatll mess your head up

Every single one I've measured have had one side sit higher than the other (and I've measured quite a few cars now) .... It's normal.

I think if you chuck the car on a corner weight scale you'll see why it was done that way.

Agreed, not many sit perfectly level. Remember you are not sitting in it when looking are you
