how to improve ML350 handling?
Kevin
How much air pressure do you use on your tires..? The valving of the OEM shocks adjusts depending on the feedback it gets from the road, which means the more pressure you put to your tires, the firmer the ride will become. Need to always to be carefull not to exceed the maximum pressure stated on your tires, and you will always want to be around 5 psi below that maximum since when the tires heat up (weather, road friction/temp, etc), the pressure will go up around 1 psi per each 10 degrees temp difference.
If you can't get a firmer ride, by adjusting your tires air pressure, and your ML wobbles too much, then your shock absorbers need to be replaced.. Tire design (side walls, reinforced, etc) make a big difference on the handling and shock performance, too..

The torsion bars make a huge difference on fixing many wobling problems on your ML (if your shocks are in good condition still). When one tightens the torsion bars, one reduces the travel of the wobling and your ML will not lean as much during turns.. If using the torsion bars, you increase/decrease the height of your ML by more than 1", you may want to begin thinking on a 4-wheel alignment.
It makes a significant difference(I played extensively with this on both my former 2001 ML 320 and had done it too n my 2005 ML 500), but then you have to find a better setting with your shocks (by means of your tire air pressure), since tightning the torsion bars produces a larger restoring force on the shocks and changes the overall tuning/dampening/ride..

Any suggestion for size of wheels and springs?

What do you think?

Something to consider as you get larger diameter wheels, they get heavier, and there is a point of diminishing returns to handling. More unsprung weight at the ends of the suspension will slow down the reaction time of the springs making them harder to transition from one position to another. Using the lightest wheel/tire combination is a racers trick.
Additional thought - I have found 18 inch wheels that weigh less than or about the same as the factory 16s and 17s. Tires in that weight range too. When you get larger than 18s, the lighter wheels are buku $$$$. There is also a smaller selection of tires and as I mentioned earlier, tire design has as much to do with handling and response as tire size.

BTW, if you have flares, the look with the 17 inchers isn't that great. With flares, I'd say 17x8.5 is a must, for starters. 18x9 up to 19x11 would be ultimate for my taste. Without flares, the 17x8.5 will look sweet on the 320.

AC, I'll have to ping you on this because I'm currently looking at a set of ML55 18" rims. I was thinking of lowering a couple of inches via the torsion bar. As I get ready to purchase, I'll have to talk to you.
