dual and triple rate coil springs?

They will consist of a longer, softer spring and a shorter stiffer spring?

I have read that these give the best all round performance "Soft ride and max grip at higher speeds"?

I honestly know nothing about cars ?

I just want a smooth ride with great grip?

Re: 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.

Re: dual and triple rate coil springs?

Always worth doing a search on old posts here.  Several discussions about suspension and road use tweaks, including this one:

Koni Raid shocks suggested, and correct tyre pressures!

Cheers JDring - but that link doesnt seem to be working? 

Also from what I can see I cant seem to find them here in the UK?

but I do also prefer a SMOOOTH ride - I shall check out the Koini Raid shocks also

Hmm, you can find it with a Google search of Triple Rate Coil Springs, but maybe I pasted it wrong.  

Try this, (although seems to be the same)

Re: dual and triple rate coil springs?

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.

Ah yes thanks - I did actually see this video - i checked the website it seems only to be for Jeep? I emailed them on facebook because their website has no email?

I'll have a search for a company over here?

laugh

More than likely I shall opt for a smoother ride as my aim isnt to be speeding round corners anyway - "wife n child and age" lol....

What would be the best combination of Shocks and Srings for the smooth ride?

 

Thank you

The rear springs on a SWB w463 are weak, so when mine gave up and started to sag I fitted LWB springs and these are still fine after 15 years

Re: dual and triple rate coil springs?

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,

Re: dual and triple rate coil springs?

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
