Pay attention to the color codes on the shocks that were with your springs, my guess is that your springs came off a car with the luxury suspension where your has a sport suspension. Did you by any chance loosen your lower control arms? This can lower your car as well.
The cut coils I removed had red tags, not sure but I think the ones from the wrecker were green. And the V6 car was a base V6 2002 mine is a 2000 with no special options like sst. But came with the glovebox 6 disc changer. So idk. And yes the lower control arms in the front were loosened when I added the sub frame connectors from the 02..but had a full alignment after.
