Post your DIY aero pics

Funny, I just came across an ad for these last night surfing craigslist..
That thing is so aerodynamically challenged you're better off focusing on mechanical grip.
A front wing could be effective, but this is a street car - you really don't want to be driving around with a wing acting as your curb feeler. And you'll never match it with rear downforce - there's pretty much no way to put an effective rear wing on that thing unless you mount it two feet above the cage tubes.

What's stopping you from mounting the wing up high in clean air? there aren't many rules for street car aero.... It certainly wouldn't be worse than some of the foolishness that has run Pikes Peak.

Anything i put on the front would be removed for street use. I was just tossing the idea of how much grip i could possibly squeeze out of it for track use. Nothing Road Atlanta-ish - Barber's and possible autox only.
A splitter would be ineffective, hence why i was thinking foil.

Some pictures from the first test day.
It was at a new track so I didn't have any previous times/data to compare.
However it turned in nicely, seemed stable and most important it stayed attached to the car!
My brother should be testing it tomorrow at our normal track, and I might get a chance next week to give it a run also.
Endplates should be on by then, canard design will be happening to. (really just going to copy Ryan's)
Overall, so far happy.

Finally got the Singular end plates installed. Waiting on the Jet Stream headlights to arrive then it will be time to work on ducting some air into the ITB's. Options are limited when the car is also road registered.

It can't clean up dirty, turbulent air enough to function, but I was able to get results with a diffuser sealing off the front and rear end of the car, leaving the middle as is. It'd definitely be better with full flat bottom, but I was able to get the tufts flowing the right way
EDIT: mine wasn't sealed above the bumper,

When you say sealing off the front was that just using a front splitter? And thinking about it,if you don't have a full flat floor but run a diffuser would having a gap between the bumper and diffuser actually be beneficial? That is if the dirty air underneath the car flows above the diffuser if it's sealed would that just increase the "parachute effect" of the bumper?

So you would think. You have to keep in mind that between the lowest part of the car, even with a diffuser, and the top of the trunk lid is the WAKE of the car. Sometimes the wake is larger and with functional drag-reducing aero, it will be smaller. The wake is turbulent air and so above the diffuser, the airflow doesn't expel differential air as we'd like.

In terms of shape and design, the diffuser itself could be perfectly functional. Unfortunately a diffuser is one part to a system. The system requires more elements than the diffuser alone to work. Without a significant amount of the airflow under the car leading to the diffuser smoothed out, it just can't operate as intended.
