Alright i installed some Tein lowering spring last weekend and my passenger side is lower than the driver side. ( I can fit 2 fingers on driver side and 1 finger on passenger side) I had a problem with the passenger side when i bolted the strut up top to hold it and put it in the damper fork. when i went to line it up with the lower control arm i had the push the hub do kinda far to get the holes to line up. I didnt have any problem put the strut on the driver side back in.
what could the problem be with the passenger side bad strut or something?
Let me know thanks

 

That's the thing about lowering springs, it won't be perfectly level because different corners of the car weight differently.

Even with coilovers if you set them equal on the threads you will have an uneven ride height. So you have to set them at different heights.

However you don't have this luxury with lowering springs.

 

Exactly the same problem was on Tein. When put skunk2 or H & R springs and has exactly the same fingers intermeddle with different sides of the vehicle
