Looking to upgrade/smooth out the suspension on my 2007 Chrysler Sebring Limited that the previous owner replaced the struts with moneroe sensatrac quick stuts and ruined the ride (too stiff and strut mounts seem to rattle, had same problem with 1996 LH that had monroe quick struts) with 2014 parts. Anyhow, I see a bunch of 3 letter codes for the struts and in the description it says touring, sport, etc. However when I get to the springs, I see different 3 letter codes and no description of suspension type, no spring rate, nothing. How do I know what springs give me what quality ride or what letter codes go to what ride quality and whethter these are convertible or sedan springs. Also, anyone swap a 2014 200 rear stabilizer bar onto a 2007-2010 sebring?
