Installed coilovers a couple weeks ago, and got an alignment. Height looked fine until I drove home and realized how low the rear was sagging. Just wondering what I have to do to keep it from dropping like that. Dampener settings will not help because that will just change how fast it will sag. Do I have to preload my springs a little bit more? And if I do that, will I have to raise the strut height to maintain the same level of drop?
