I know that springs have been covered ALOT in here. I have researched every spring topic and still cannot get the answer that I am looking for. That's where you experts come in. Ok here is the deal.... the manufacturer designs the springs with the shocks (so they work well together) i.e. proper height for the spring when no load is on the car...also they calibrate the spring with partial and full loads as well. (you guys already know this) These two parts(springs and shocks) work together because of how the designers fabricate them. If you change the springs (I am looking into the TME) and the ride height is lets say 1/2 inch drop all the way around. What is keeping those "stock shocks) from being ruined or damaged because of the "ORIGINAL" set up being altered.????? I would think if the "stock" springs are at a certain height and then you lower them 1/2 inch that the shocks are now "at rest" alot lower than stock, I would think if the shock is not designed to "rest" at this height that it would put alot of "stress" on those shocks because they are being compressed at a different rate than they were designed to be. Would'nt that be the reason that the dealer will not warranty "different springs" All help is much appreciated. Hopefully this message is not to convaluted" Thanks Rick

... What changes with the 4C setting is the valving. It's hard to explain, but simply, there are valves within the shock that adjust all the time.... regardless of 4C setting.

I thought Volvo uses magnetic-fluid shocks which is really cool but some quick googling shows only GM is usig this technology.
Go to this link and do a CTRL-F and find "volvo" and you'll jump right to the piece related to this http://www.epinions.com/content_113876569732
Not a big deal since I believe 4C boast 500 adjustments/second versus the 1000/secod for GM's magnetic-fluid shocks.
This link explains the technology:

Does anyone know how Volvo controls the valves for the 4C system?
