I have the same setup (5th gen rear springs in a '97), and I like the height and the ride.

One thing that bothers me is that like said above, the 5th gen spring is somewhat bigger in diameter than the 3rd gen, so it does not automatically get centered on the seat during installation. I tried to centered it as best I could, but I am sure it moved a little. And with the spring not centered, a portion of it sort of hangs off the spring seat. I don't think it's going to outright fail, but I would like to find a way to center the spring on the seat.

Would the trim packers do that, or are they only for increasing ride height?
