lowering an E320 wagon
struts, sway bars etc can and should be tightened, and once lowered any worn parts in the suspension can result in rubbing issues.
I went lower, but raised back up to ride on Sportline springs,
a slight drop, but they maintain a very MB ride.

1: The self leveling system allows a trick to reset level after lowering. Fairly simply, search the forums.
2: I tried springs only at first, was curious of the effect. Was okay, but then added Bilstein sport struts. Added to a fully refreshed suspension, it gives a sense of new-ride.
3: I started with H&Rs but ended with Sportline springs, have made this choice repeatedly now. Sportline springs are a tweener, not as low as we like but, great no-sacrifices ride.
So JMO, but the Sportline springs were worth switching BACK from sportier lower springs on several of my cars. (Cabriolet too)
