The front sway bar leveled out the cornering some and helped the side to side rock that came with the larger wheels and tires.( I had installed 16inch wheels with 225/50/16 tires previously.) But, this made the car feel very twitchy. I subsequently added HD Bilstein struts front and rear. This helped A LOT, single most dramatic upgrade, fairly easy install. I'm hoping that these springs will lower it slightly and firm up the ride just a little more, ridding me of the residual sway. I have the special spring compressor made for Mercedes cars, and I'm going to carefully tackle this tomorrow evening. I'll let you know how it goes. This should yield me the closest thing us 400E/E420 owners can get to a sportline.
