Performance parts?

Just out of interest, is there a company that makes performance parts for mercs? (Not including in-house AMG, and Brabus)

Lorinser is the only one that comes to mind.

There are also Carlsson and Kleemann
Carlsson is from Germany

Kleeman and Carlsson are pretty well known and respected for their performance kits. They're the only 2 (besides Brabus) that I would actually trust to build a reliable performance upgrade for a Merc.

What about these guys? :sunglasse TurboWorks Engineering (http://boykinracing.us/index4.htm)
