over the weekend I worked on a diffuser for my frc. I managed to snag a stock diffuser from a lotus exige, widen it about 2 ft and add some elements to it. it is sagging on the edges because of lack of support yet. but thats my next goal for the week. it does close off the whole rear section all the way to the sway bar.
A friend of mine makes race diffusers for lotus's comparing his to c5r diffusers they need to stick out this far to smooth out the air. I wanted it to be as functional as possible from the side view it doesn't stick out very far
Bet that thing would last about 10 seconds in a wind tunnel, looks like about 1/2 the Honda's I see with this glued on stuff. I'm sure that piece was tested extensively on the car IT WAS MADE FOR. The rear of the C5 is HUGE already, then you add this cling on, looks like 10lbs of doodie in a 5lb bag. Functional, i don't think so.
This is what that's SUPPOSED TO look like (actually doesn't even look all that great on the car it was made for either)
why do you think it wouldn't last 10 seconds in a wind tunnel? what would its size have to do with that? and neither of those articles say anything against what i have on it. its not glued on, it's bolted with adjustable rods to set the height and attack angle. if you just don't like how my car looks. i'm sorry to hear that. its a good thing its my car.

I'm curious. What is your personal experience with racecars or aerodynamics? What makes you an expert?
Without testing in a wind tunnel it's pretty much impossible to say if it would improve the aerodynamics or make it worse. That was made for a Lotus including its design characteristics.
As for aesthetics I don't know why this poor tandt guy is getting a new one ripped just for stating his opinion on a public forum. I happen to agree with him, I think it looks way off. Sorry...
