I have seen a lot of carbon fiber diffusers on vehicles most of them the back side looks cheap (can see fiber glass). I just recenlty seen one with a plastic backing but customer forgot where he purchased or what brand. Anybody know of a quality rear carbon fiber diffuser that will fit 2011 C63 (without that fiber glass backside).

I am in the same boat as I am looking for a decently made CF diffuser for Prefacelift and I am unable to pinpoint quality and design. So far I am shopping:

RW Carbon
JB Speed
Euroteck

Anybody really happy with the fit and finish of their diffuser and highly recommend it?

Does it matter?
You will never see the backside once its mounted. Rear diffuser also won't take damage unless you back into something.

RW Carbon

The backside is ALWAYS going to be fiberglass. I believe even the Vorsteiner one is not CF on the backside.

Not so much worried about the fiberglass aspect. Looking more at fit, clearcoat, and fin style. So far I am really liking the customer service RW Carbon provides. Just deciding on the smaller fin diffuser over the big fin.

Hopefully I can get around to ordering by this weeks end.

Exactly ALL the backsides are fiberglass and painted black to try to cover the terrible craftsmanship. Correct you will never see the backside but I know it's there. Refuse to pay 400 or more for some cheap China made crap. Look at real MB carbon fiber and tell me there the same. MB does not make carbon fiber diffuser for 2011 model year otherwise I would buy MB. Looking for quality a 70k car deserves.

Take your OEM diffuser to a shop to overlay CF on top of it. End of story.

Does MB actually make a facelift carbon fiber diffuser?

Does MB actually make a carbon fibre diffuser for facelift C63's?

Facelift model yes. It's slighty over $2,000 and looks great compared to these aftermarket ones. Just wish was for preface lift.
