So I've only had my 2011 S350 for less than 6 months and I've been haunted by a failing Airmatic suspension.

Did some research and it seems that the only option for a regular suspension for the W221 is from Youzealand (Japanese workshop/brand) because Arnotts only makes kit for W220.

Does anyone have any experience with the Youzealand Black Series kit?

Thanks.

Strut Masters has a kit for the W221. Its on my 2007 S550 4matic, that I got a few months ago.

How is your experience so far?

I like the struts and coilovers. It seems like a nice setup for the car. I am not sure if I am getting a little rubbing when going over a speed bump, or there is someother rubber component in the suspension that is making this sound. The ride is similar to the sport mode with the OEM. It corners and handle well at all speeds. I don’t have a warranty and do most of the repairs and service work. So I like the concept without having the risk of expensive repairs looming.

I have just installed the coilovers from Youzealand and I have to say that I'm not really liking the ride on the car now.

The roads are pretty rough where I am now (worse than LA), and the car just bounces everywhere.

It does handle and corner much better than Airmatic, but the trade off in comfort is just way too much.

I'm hoping that it will settle and get softer after some period of use.
