Lowering
Don't waste your money on aftermarket springs. They won't control rebound and make all sorts of weird noise. Get the MBZ OEM ROW springs and struts. This is the most cost effective solution about $1,200 for springs and struts. Factory parts always work better on a daily driver. Try CEC in LA. If they don't have them they can order them. They will give you a tasteful drop of about 30mm and the handling is a big step up from USA spec.

This sounds more like opinion than fact. AFAIK springs don't claim to control rebound. On top of that, I don't recall anyone on these forums mentioning weird noises from the springs.

Dampers control rebound, not springs. However, it is possible to get aftermarket springs that are too stiff for the stock dampers. Then it would be the stock dampers that cannot contain the rebound caused by the springs. I think that the factory solution mentioned would be good because it is designed as a package. At the same time, it is quite possible that the stock dampers are perfectly capable of maintaining a quality ride with some aftermarket lowering springs. It is also quite possible that aftermarket shocks are available that have the necessary damping rates to contain certain aftermarket springs. Unless you have shock dyno data for a damper as well as a tested spring rate, its all guess work.

agreed ... it is important to match the dampers to the springs. i used the "eurospec" springs to lower mine (about 1.5 inches). of course, im not doing laps at the monaco GP or anything, but the stock dampers work fine with the euro springs for my purposes, with no noticeable ride difference after the swap.

Since you guys are bringing up the european spec springs, any idea on their spring rates? Are you getting them from the dealer or what?

I'm using H&R springs with custom Koni's. I find that the H&R springs are not stiff enough. I'm using the thickest spring pads front and rear just to keep the ride height high enough so I won't bottom out. I may get a set of Advanced Design shocks and increase the compression/bump to compensate for this, unless I can find another set of springs with stiffer rates or else I'll have to go to coilovers.

The reason I like the Vogtlands is that they never "bind." On the 190 the springs are stiff, but are wound tighter so there is less room for travel. This causes them to fully compress on occasion which feels like bottoming out even though there is still theoretical room for tavel - it's just the spring that runs out of compression room. Not sure I explained that well after a few beers, but do some searching and there's a post somewhere comparing coil counts and compression rates.

not sure what the spring rate is, but it is a 210 part off of an e class. you can get them from the dealer with the part numbers, but i ordered them online.
