Z3 coupe height difference rear left and right

Hi,
This afternoon I discovered that the clearance the distance between the wheel and the rear wing differs with about an inch from left to right side. Broken spring or something more serious?
Any suggestions?

Look for a broken spring. I found three broken springs on my roadster as I upgraded the suspension.
By the way, OEM springs are rather expensive and hard-to-find (at least in America). You should consider used parts, aftermarket springs (usually lowering), or a complete upgrade (such as coilovers).

There is a little more info here:

and there is a lot of info on springs and suspension here by using the "Search This Forum" button near the top right.

A front wheel on a rise would have the effect of pushing the rear wheel on the opposite side up in the wheelwell.

I knew which end you were asking about!!

I put on a completely flat surface. I turns out to be 5 mm difference only.. and I did that after I ordered new springs... Special order and already arrived at the dealer. Couldn't cancel..
After 90k km it can't hurt to replace them. 550US including labor for OEM springs.

I had the same concern with my roadster until I measured the dimension between the top of the lip of the rear fender to the center of the wheel (center of the roundel) and got the same dimension within 1/8".
I still see a difference when I look at the back of the car but my measuring tape saws otherwise.
