Default Uneven Rear End

I recently put two new rear tires on my 1996 C4. Tires are exact matches and the same size, brand and type (Nitto NT555 315/35/ZR17).
When I got the car back, I noticed the right side sits about a 1/2" higher than the left side.
I've never noticed this until after the new tires were put on, maybe it was like that before and I just never really looked closely.

What would cause this? I'm not completely confident in the business who put the tires on so could this have been caused by the mounting of the new tires?

Thank you.

Go find yourself a section of highway with "rumble-strips" on each side of the traffic lanes and hit the "rumble-strips" with each side of the car for a short while a couple times. That should settle the suspension easily! A couple car lengths a couple of times should be sufficient!

No, not unless they put different size tires on each side. It is unlikely that even a less than professional shop damaged the suspension by lifting a C4. This issue has been brought up before, and if we all go outside and check, many of us will find that the driver side sits 1/4 to 1/2 inch lower. You could try cranking up the nut on the bottom of the driver side spring bolt a turn, or loosening the passenger side nut, if you have enough threads to get a cotter pin back in. Loosening puts the wheel higher in the wheelwell, lowering the car, tightening lowers the wheel, raising the ride height, hence the longer bolts in the lowering kit. But having too much side to side difference could cause some slight handling issues.

I've jacked mine up by the K-member or banjo and had slight differences is side to side measurements. Bounce it up and down a couple of times settled it in. If it was even before, they put the same size tires on both sides, I expect it will even out after a few bumps.

Look underneath the car. Maybe they put the jack under the floor and did a major tweak in the body. Just an idea.
