Dome ST205 rear diffuser, abandoned project.. Options

[samir0189]

I've come across some information on a abandoned ST205 project - A rear diffuser for the 6gc.



Dome specializes in aerodynamics and has built quite a few race cars. According to Bespoke Ventures Blog, ...

... Dome decided to fix the biggest aerodynamic flaw of the vehicle and create a prototype-style underfloor and diffuser. This isn’t just form being secondary to function, this is function being the sole objective of the part. Dome measured a 9mph increase in top speed, a 7.8% improvement in fuel economy and a very useful 200lbs of downforce.

Unfortunately this project never developed beyond a prototype. [As far as I know based on information..]

My question is, has anyone else designed a rear diffuser for the 6gc, seeing the obvious performance benefits that it can have on our cars? And if not, can anyone fabricate one?

Edit: spelling

any time you can get the air under the car to move faster than air over the car you'll get positive results.
When i get to this point i'll have pics, but i will be building a composite flat bottom and rear diffuser for mine.

nice, but if I'm not mistaking you're building yours for track use only right ?

I would really hate to see this cracked in half on a biggie size speed bump. you're right about the aerodynamics effect of air flowing faster but I still think this is not something intented for street driven cars because of the cost, but then again I have a BIG spoiler that won't do much for my auto ST so if this makes someone happy, I'm not the one who will say no.
