I am interested in getting a sleeve kit for my car in the near future so I can lower her about 1". Anyone on here have the KW or Weistec HAS (sleeve kit)? Any feedback on ride quality and/or issues with the adjustable dampers? I am planning on getting this done and also getting a set of aftermarket wheels.

I have the Weistec adjustable suspension. I'm lowered all the way in the back but half an inch up front. No scraping issues unless you take a bump like a normal person so now I take bumps slow and that solves that issue. If it's a severe dip chances are you will scrape so approach with caution.

Kw has great reviews from people that are using it.

I'm planning to get the same along with some spacers.

Can you comment on the ride quality compared to stock? Is it the same, better, worse? On my 2011 BMW 1M coupe, I found the ride quality actually improved after I changed from the stock M suspension to KWV3 coilovers. I really would love to lower the C63 slightly but I do not want to sacrifice the ride quality as I think it is already too stiff to begin with.

KW has no part numbers in the US. So my question is...where is everyone getting their suspensions from?

I too am interested in this topic for future use

Can people chime in who have or have used the "sleeve kit" only as per original OP's question, not the whole KW or Weistec replacement suspension kit I don't want to swap out the whole OEM set up just want to add height adjustability to the original OEM set up

I have the KW HAS Kit installed on my car and it is by far the best mod. It is only slightly firmer than OEM and allows me to use the OEM Switch to change the dampness settings. On my old W204 C63 I actually installed Coil overs and that was relatively harsh. The HAS is probably the best way to lower and slightly firm up the suspension on the newer C's.

Hearing nothing but good things about the KW HAS!

Good to know, I'm definitely getting them for my coupe.

Ride quality with the Weistec adjustable suspension is better compared to stock. When I'm driving I am usually in Sport+ (99% of the time) and it's pretty stiff but the road doesn't feel harsh. I don't have to take bumps at an angle either just slower because the front will scrape. The def feels like it can handle better. I notice when I take a hard turn it kinds "forces" you in to keep you planted. Also I didn't even have to realign my car. I'm definitely keeping an eye if it starts to lean or the other. Installation is a ***** my mechanic said and will take about 3 hours to complete.

Thank you, that has answered the question

Although it's unfortunate to hear that it rides a little firmer than stock OEM as most say the ride is definitely too firm already in comfort mode.

+1. I was hoping that perhaps the ride would be the same or perhaps even a bit better. The HAS uses its own springs? Anyone know if either the KW or Weistec use progressive springs? That would help with ride quality on daily driving.
