Does anybody know what the stock springrates are on a W210 sedan? I'm getting pretty tired of my dually pickup having better ride quality and less roll and want to see what the stock rates are. My car has new OEM Sachs dampers on it as of about a year ago and it just rides like **** and rolls around like a Buick. I have a spare set of stock springs here I can send off to get measured, but thats probably ~$100+ I'd rather not spend if I don't need to.

Are you interested in a set of W210 H&R springs? I have a set that I removed from my W210 and are sitting in the box in my garage.

Spring rates don't change as a spring ages, what is the history of this car?

You want a softer ride but less body roll, these are conflicting requirements that can't be solved with a solved with a spring rate change.

If you want a softer ride, you need less LB per inch of a spring compression.

If you want less body roll, you need more LB per inch of spring compression.

On the shock side of things:

A stiff shock in compression will give for a hard ride. A stiff shock won't limit body roll, it will only slow the rate of roll.

What size . brand , air pressure are you running for tires?

To properly rate a spring, you need a seat contoured to the spring otherwise the reading will be off a bit.
