I installed lowering springs on my t/a passenger side is fine. Drivers side sits a bit higher. I did have the car jacked up for over an hour because of a broken shock bolt. Do these need to "set in"?

 

Are you sure the spring is seated properly? Reason I ask is I had one side that I had to work with one side spring to get it right, same problem as you're having.

 

yeah I checked again today. What I noticed from old pics is that the old springs also sat a bit higher on the drivers side. I removed both rubber mounts from the top of the front and rear springs (drivers side) and replaced it with hose rubber this made the car sit properly or damn near close anyway.
