Basics: 04 LS V8 Premium Sport 227k miles Car is starting to get a little bouncy, not horrible but noticeable. I have gone through these threads and a few others: 04_Sport_LS's Suspension thread My kingdom for sport rear shocks The rear Bilstein B4 shocks will work with the LS rear springs but the fronts need the Jag front springs. Ideally, one would replace all four shocks and all four springs. I can't pull the trigger on $800-900 for new springs and shocks all around. Do springs usually wear at the same rate as the shocks? Would replacing just the rear shocks and reusing the existing sport springs be feasible? For the fronts, an option would be getting used Jag springs (PYP) to match the Bilstein front shocks. Or just replacing rear shocks at this time... Again, I understand that this isn't ideal just looking for a little input on options in light of limited funds for this project.
