Got the car back today. Heading up to Watkins Glen in the morning. Honestly, I did so much at the same time (KW Clubsports, full KMAC bushings, Spoon Rigid Collars, and DIY endlinks), that I don't think I could tell you exactly what these did. What I can say is that the car is super stiff now, and these couldn't have hurt. As part of a comprehensive effort to make the chassis bulletproof, I think these are worth it since they're relatively easy to do. Will have more feedback after a couple of days on track.

Got my set in the mail couple days ago, will be putting them on the car sometime next week. Should be able to give a more accurate feedback as to whether these things work or not.

I found Spoon english website and they do have dist all around the world so maybe you can buy from there?

Still damned expensive for what they are. My bet with some measuring of the hole diameter and the bolt diameter one could get these made at a local machine shop a lot cheaper.

Any follow up on this one?
Ooooooh a 6yr old thread resurrect!
Just ordered these after doing quite a bit of research on them and finally tracking down a full set on eBay. Making my push now to get the car track-ready for spring - also have KW Clubsports and adjustable end-links on the way, and might pick up a full set of KMac bushings as well.
There are going to be a lot of changes all at once, but I'll let you guys know what we find when we take apart the subframe to fit these Rigid Collars. Got the idea from Phil Chow's post here: https://mbworld.org/forums/c63-amg-w...ml#post6925307
Here's the info video in Japanese: https://www.youtube.com/watch?v=c1zuDJ76TGY
And in English if that's more your thing: https://youtu.be/zWyUD6UXfog
Plenty of reviews out there, and a lot of theoretical debate on whether or not they are effective - here's a decent laymans-type write up: http://www.speedhunters.com/2011/06/...s_to_the_gt_r/
Decent engineering debate here a few pages in: http://www.iwsti.com/forums/gr-suspe...ollar-kit.html
Thoughts? The theory is.... sound I guess, and they were inexpensive enough to give it a shot. With the addition of stiffer bushings all around, and adjustable control arms/bushings/camber plates, I think there could be some benefit here....

Yup. Installed. Car is stiff as **** now. Absolutely no body give and flat flat flat through corners. I did KMAC bushings all around and KW Clubsports at the same time, plus I have the full set of Ultra underbody braces on. As a friend said, it's the "least comfortable Mercedes in the world" now. 
Tough to tell the exact difference these made, but they certainly didn't hurt. With that said, I think they're probably one of the last things to do, not first.

Can any help with fitting the front set for these, as the subframe has to be dropped did you have to use an engine hoist to support it from the engine bay?
My installer only works on BMW’s but is willing to do the job but seems to think because you have to drop the subframe to fit the upper collars it needs an engine hoist to support from the engine bay.
