Anybody running the HMS Tuning rear diffuser on their C63?
Hey guys. Anybody out there running the HMS rear diffuser on a US spec car?
I'm interested in placing an order buy my concern is that it might not fit my US spec 2009 C63 if euro rear bumpers are different than the US rear bumpers.
Can anybody confirm that the US and Euro rear bumpers are 100% identical?

The Revozport diffuser is similar but has a two piece design, doesn't go as wide as the HMS Tuning diffuser on the underside and the carbon layout of diffuser and underside piece goes in opposite directions. It's almost as if the underside piece was an after thought.

I've been in email contact with them and they're responsive a nice guys. I also sent them pics of my rear bumper so that they could visually compare US to euro rear bumpers. Based on their visual comparison, HMS thinks that both euro and us bumpers are identical.
It would be great to get a second opinion of somebody that knows 100% that they are the same or if somebody in the US has successfully fitted the diffuser to their car

Looks nice but i think the edges near the exhaust tips are not OEM looking from some of the pics I saw on the site. Let us know how it goes? How much did they quote for it shipped, if u don't mind me asking?
