The black plastic part that encompasses the exhaust tips and reverse light is a rear valance. The black plastic part that attaches to the rear valance and has the air scoops for the rear diff cooler is a close out panel. The GT350, and most cars in general, don't have a true diffuser. Marketing people use the word quite often, because it sounds like a race car part, and they apply the word to what is a rear valance.OK I know I should wait until after I see pictures, but I just want to get some clarity because when I was referring to diffuser, I was referring to the lower black plastic portion that houses the reverse light and exhaust tips. It sounds like you might be referring to it as the valance.
So your piece will not be replacing the valance (diffuser), but attaching to the bottom of it? It will only be replacing the close out panel?
Interstellar, I’m not really stoked on my Verus so hopefully this is a better product.
Data: I'll work on that over Thanksgiving break.Nice work- Sign me up .
Data? Price? Ship ready date?
I've spent months and months, during these stay at home shutdowns, continuously innovating. One of the very key parts that has had a whole lot of attention thrown at it has been the CORSAIR rear diffuser. If anything good has come from the COVID shutdowns and social distancing, it's this part.
The CORSAIR rear diffuser mold is out to bid. What you see in the rendering below is 97% of what's going to make it into production. It's already run multiple CFD configurations (ride heights along with subtle vehicle rake degree changes, clean and dirty bottom, and various air speeds) and the results are awesome! I'm going to be throwing gobs of data at you, in future posts.
Working with the carbon fiber team, we've brought so much goodness to this part. Features that aren't even a thing in the industry yet. This will be a 30-45 minute install. And I'd estimate half of that time is getting the OEM garbage out of the way. Billet aluminum supports will be employed, both front and rear, replacing the OEM plastic junk. Full 2x2 carbon twill and forged carbon diffuser panel with carbon fiber removable and replaceable strakes! Literally, six button head allen drive stainless bolts will mount this diffuser to your S550. Although it's really geared to the GT350 and GT500. Full compliment of strakes replaced in 5 minutes. Or just removed to make trailer loading a breeze in less than 5 minutes! How freeeeekin' cool is that?!? This also means the strakes can be mega aggressive. You're just replacing an individual strake, as it wears out. You keep running everything else. Sustainability. I love it.
The NACA ducting required for the OEM rear differential heat exchanger is totally modular. You can have 3 ducts, 2 ducts, 1 duct, or no duct. That would be for the cars that have the heat exchange plumbed into the trunk area. But totally modular, none the less. Right sizing the ducting and it's orientation will maximize the diffuser's affects.
The CORSAIR will be available with two strake designs. One like you see rendered which will be the TRACK option and there will be an 1 3/4" strake more suited for street use for those that feel so inclined. Pricing for the CORSAIR, strake options, and billet aluminum uprights will be released shortly.
More to come, very soon. Oh, and there's that super sexy SPECTRE Quantum swan neck wing in the rendering too. Blame the CORSAIR delays on that, but it was totally worth it! I'll start another thread on that part, in the very near future. Deposits are still being taken for the CORSAIR. The head count is currently at one dozen units. PM me for more info.

The simple answer is yes. I have a customer that plans on doing just that. The diffuser’s mounting and position is by no means dictated by the rear valence. There’s also an option for custom strakes for those that will be removing or trimming their plastic rear valance.Would you be able to run this with the factory valance removed?

Nice work, beautiful photography, couple easy questions:
#1: How much downforce is produced by this diffuser? I imagine wind tunnel/ before and after data is expensive, and I confess, I don't know if this can be extrapolated from available data from high dollar racing units that use the same s550 platform. Standard for downforce measurement ? ( at expected speed where benefits occur ( for example, at 100 mph ). It looks badass, but what is it gonna do for my GT350 on the track, with or without your wing, or another wing that adds it's own, downforce ( and drag ) and bolts on my trunk lid. If you know the numbers by calculations, without or without renting wind tunnel time, the required addition on the front end to balance the car's "enhancements" ( front and rear downforce ) should be predictable, and I can purchase the hardware knowing the homework has been done. As cool as it looks, and with the thought and designer pride you have obviously put into it, If it doesn't make my car better on the track, I may need put the dollars elsewhere.
#2: Price? ballpark price? Secret? If I have to ask I can't afford It?
#3 and #4: Same questions on your swan neck wing.
Without advanced degrees in aerodynamics and the sophisticated understanding you referenced in earlier posts, I really don't know how to shop intelligently, without data. Splitter? Cannards? Wing? Diffuser? Buy everything that looks cool and then drive and see what happens? If I can avoid trial and error because someone has already done the math, fantastic. I just want to buy stuff that works, and otherwise pay for track time and expendables...
The parts you have designed ARE pretty enough to buy just for looks, if that's someone's thing.
I appreciate the hard work and artistry you have put in, the quality products you offer, and the poetry and pride in your postings-
Totally understand your point. All anyone would have to do is click on the link. I'm not being secretive at all.@eighlug I can see how it would be hard to remain neutral when you have hundreds of hours into the proper design of a component like this diffuser (and the associated pride), though I would also not expect this to be the last time someone will ask you if you have any performance data to share. I would expect it to be a common question when people are considering throwing down $4k+ for a diffuser.
Thank You .CORSAIR Rear Diffuser | Archetype Racing
This is an aero component that has been long overdue for the GT350 and GT500. I present to you the Corsair rear diffuser. Fitment will apply to all S550. There are 150+ hours of CAD/Solidworks by Reut Design Co. and more than double that in multiple CFD configurations, before a working piece was...www.archetyperacing.com
