dual and triple rate coil springs?

Hey,

I don't care much to switch out OEM products, but on a G the suspension can be improved a lot.  Not too sure about dual/triple rate coils, but they seem like a good idea.  There is a good explanation of their function here @2:40 into the video.

I like softer suspension (like on G230) and don't off-road much in my G's (nowhere to do so for me).  The G350 suspension seems good for motorway cruising.

The short answer: If you want a smooth ride with great grip you have to buy a Porsche 996 onwards.

The idea that different dampers/ coils will change the driving characteristic of a G is not realistic, it is the attempt to transform an ibex into a greyhound. The G’s suspension design consists of a double wishbone axle at the front and rigid axle at the back. This suspension design optimises off-road traction at low speeds.  As the unsprung mass is high, the reaction times of the suspension is slow and on-road comfort and traction suboptimal. 

Brabus once designed a suspension for the G with adjustable damping characteristics:  https://www.autoevolution.com/news/brabus-offers-adjustable-suspension-for-mercedes-g-klasse-22463.html  It achieved nothing, I have not heard a single positive feed-back.

From experience, a G350 on 16 inch wheels is a great motorway cruiser but lousy around corners.  On 18 inch wheels, the ride is harder but traction is improved.  But even then, if you push the car, the traction on the front axle is insufficient, the design can cope with the torque/ HP of the diesel engine only in straight line acceleration.    

Because of the weight difference between different G models (W460 230 convertible = 1,700kg vs W463 350 LWB = 2,600kg), a one-size-fits-all suspension set-up will not work in any case. Interesting to note in this context, the suspension becomes more comfortable the heavier the car as the relationship between sprung/ unsprung mass improves.

Smooth ride, standard Sachs Oil Damped shocks, cheap if you cross reference numbers, Spidan springs with yellow code I think, tho you can check correct colour with Spidan catalogue,  will roll around corners, but will absorb most of the bumps.

Spidan good prices on Ebay in Germany, 

Afraid you have to cross reference Sachs and Spidan Catalogue,  thought I had info written down but can't locate.

Would go for Sachs Heavy Duty , have expensive list price but often available with serious discounts
