Interest in B7 RS4 Rear Diffuser?

[Rw@@dy]

How's this coming along?

I am very interested also if it comes off
Cheers

Apologies for the lack of updates, but it's been incredibly busy.
Progress to date on this includes: original bumper/trim purchased, initial 3D scan data taken, initial CAD mock-ups created.
Prototype is yet to be constructed, but is amongst the next steps (which also include refined 3D scans/CAD - at which point, the imagery should be of sufficient quality to share).
Plan to send out a newsletter on progress to all that have subscribed via the poll on the website, including images of the prototype, once it is completed.

Nice one Nick - I'm sure it'll be worth the wait!

This looks good.

B8, though, no?

[docurley]

A6 I think, the cars so modified I can hardley tell but the style of the diffuser looks right.

[MikeFish]

The boot hinges are definitely not from a B7.

[TechNick]

It's a B8 that I'm familiar with. An A4 that's been very heavily modified with widebody, etc. and even a V8 powerplant.

Just seen more of it and yes it a B8 A4.

Just an idea, I found this video on YouTube, the RS4 cabby has a carbon rear diffuser which I think is quite nice. It looks quite OEM and not sticking out too much. Not sure if it can be used on the avant or sedan (mine is a cabby).

It appears to be made by a company called CDC Performance. Have anyone heard of them?

Good find!

The shape of that looks great - you get a good look at it around 0:50 into the vid.

Looks like a one off carbon part though; their website alludes to custom made parts, and 3D scanning techniques as Nick is using.

Absolutely!
At the risk of sounding overly critical, both of the recent examples look like one-off, hand-laid, manually crafted parts, as both have a few imperfections.
Again, don't want to come across wrong so please review them in detail yourself (preferably on a computer with a decent graphics card and large monitor) and make your own mind up, but a couple of clues included below, to illustrate how I would reach such a conclusion:





By comparison, a snapshot of some of the CAD data used for the B8 diffuser, which was then used to CNC machine the mould that the parts are made from:



The 'slices' shown on that image were just one of the sets applied to ensure accuracy, symmetry and that the light reflected in a consistent manner that flows across the surface.
Massively over-engineered, perhaps, but an example of the attention to detail applied.

...and as for the CF window surrounds... personally, I'm not a fan of 'stick on' CF parts.
In fact this old article sums it up for me, and IMHO.
