A nice coating of gelcoat will keep oil and water out of the wood.

Thanks Emilio. I have tried to make it usable but without a modulus for all it makes it design decisions much harder. I am working on it

Modulus key.
Failure mode also important.
Does it stay bent or shatter.
Abrasion resistance.
Cost per square/ft.
Before Alumalite, birch was the next best thing to Tegris or dry carbon.

That is an interesting point you make.
Perhaps there needs to be an idea of where the bend shatter cross over is.
Although given the range being very grouped I guess it won't be accurate.

I've been considering whipping up a wing setup for my car, and an end plate mounted wing came to mind, since big end plates seem to help with efficiency and normal uprights disrupt flow.
Is there a good reason why they're not used in GT cars or other racing? It's prevalent in F1 , but I wasn't sure if that was due to a restriction on F1s side, or a restriction in other race classes. the NOPRO guys used it on their GT300 car, but that wasn't exactly a winning car.

Not used on GT3 cars due to rules- note they are used on LMP cars.
Mounting on a Miata is a challenge, note how small the wing in that picture is. To have a full sized 65-68" wing you need to make some kind of fender mounts.
It's often easier, lighter, cheaper and stronger to just have a gooseneck setup. Which you often see on GT/GTLM cars.

Question to those who run a splitter + flat underbody (+ diffuser): do you still run the stock undertray? I've seen a lot of splitter setups, yet nobody seems to shield the engine bay from the high pressure wheel well area. I guess this must decrease radiator efficiency, wouldn't it? Or does the wheel well have less pressure than the bay?

I have full splitter only and ditched my undertray. Front airdam is tightly ducted to radiator and I have both hood vents and fender vents. I figure the combination of those two should be adequate to pull some air out of the bay, not that I'm really concerned about bay temps- my intake tube is wrapped and ducted though the headlight, and nothing else under there is going to get hot enough to care.

I retain the stock undertray, but the fender liners are both missing.

The wheelwell holes by the headlights are problems. Fender liners or front mini tubs would be huge to minimize wheelwell air volume. Build them as close to full bump travel as possible.
