Thanks man, I'm pretty excited with how it turned out. We'll see how well it performs on the track this weekend.

only thing I don't like about the Lotus diffusers is their outer channels are pretty much worthless due to tire squirt contaminating the airflow.

What's tire squirt? As in the air that's being directed off the tires?

it is the turbulent air that is a result of the rotating tire moving through it. There is a way to fix it though, and that would be to add a fence to the outside edge of the channels that extends forward.

A fence? What do you mean? Sorry for my lack of knowledge, I'm basically clueless when it comes to aero. I'm assuming I just make some sort of an extension on the outter sides to kind of block out the turbulence?

correct, extend the outside fin further downward and forward.

Right on, I'm assuming just riveting a sheet of aluminum should work fine?

Wow that looks great, if only I had enough power to fully utilize all that down force.

That was my first thought. I try and build in a weak point for those occasions, and when I look again at that design, I think the weak point is the lower part attached to the splitter, where the round hole is. Just unbolt, apply a BFH, and it should straighten enough to work ok if not win a beauty contest.

Ouch that's a good point, I didn't even think about that.

Almost finished my aero setup for this year! Should try it tomorrow to see if I need a center brace for the spoiler.

Took me a second to realize the garage door hinges weren't part of the spoiler, LOL.

Allstar 24" sheet plastic, which is wide enough for a Miata air dam. Comes in a roll. .070 is not quite stiff enough for air dams, use the .100. Google search, it's everywhere.
