Ride height difference - driver and passener sides

I was checking the ride height of my '07 ///3, and found the right side, in my case the driver's side - 79 cm compared to the passenger side - 77 cm. This is of course from the ground to the edge of the wheel arch. I am on standard OEM suspensions and planning to swap to H&R soon. Can anyone enlighten me as to why this is?

The only thing I can think of is that it's compensating the driver's weight and brings it to level.

Don't measure ride height from the ground because the ride height at each corner is influenced by tire pressure and remaining tread depth. Also, make sure you are taking measurements on a flat surface. Most people measure either from the bottom lip of the wheel or the center of the wheel (center of center caps) to the fender.

All manufactures have side-to-side and front-to-rear ride height (or frame) tolerances - not sure what the M3 "acceptable" ranges are but most cars are on the order of 1/4-1/2".

Thanks ... will try again with the suggested points.

I don't have an explanation but all 3 of my e92's were lower on the rear passenger side. Even after changing springs (Dinan, Eibach) they were still lower there.
