In my opinion, I think a problem for most of us here (myself included) is that we are shade-tree mechanics, not exactly trained in working on vehicles, particularly 2005+ Ford Mustangs. I like working on my car, but I am no expert and try to follow the directions, but there are always complications and things not described in the instructions. Also, Ford engineers spend years with computer models, etcto design the Mustang, they have reasons for every component they use or design. I think we mess with fire when we try to make modifications. As an example, one thing I've read is that one of the reasons for using softer rubber bushings in the LCAs is because they are required to flex to handle the axle movements during bumps. When we all replace our LCAs with ones with poly bushings, we are removing this flex, an integralcomponent of thedesign,causing rougher rides and who knows what else in the longer term.

Myself, I'm almost ready to take my car to the dealer and ask them to put my whole suspension back to stock to try to cure my rough ride problems (I bought the car used with many suspension 'upgrades'). However, when they quoted $550 to just replace my springs,I figured I'd just do it myself .
