I bought a 2010 ford Fusion SE and I love it. The other day we went camping and decided to ditch the wagon for the Fusion. It was a good choice since the cabin is wonderful and even having 4 people on board plus equipment the car was handling well. The only problem I faced was the sagging rear suspension that showed how low the spring rates were. It looked like the rear was grinding on the road and backing up was always worrying. So my question to all is this: How can the rear suspension be improved to allow proper leveling when loaded. Options: 1- New Springs: I looked at changing the spring for something stronger but since most of the time I am alone in the car I do not want a bouncing rear suspension. 2- ail lift boots: I just saw those on the internet but I do not think they fit since the rear suspension coils are not hollow, they seem to have a rubber stopper in the middle. 3- ... Any ideas ?
