Agreed Lips are replaceable . So are engines but at a much higher cost.

It's probably negligible, but I can't help but think the shape of the stock piece has some aerodynamic effect to aid in extracting air from the oil cooler, it even has a leading edge wicker on the vent. Plus the air directors in front of the wheels serve a purpose to reduce drag created by the face of the tires. I'd love to see an aftermarket skid plate incorporate some of these vs. just a flat piece. I recently bought a new OE belly pan, and while not as as rigid and strong, they switched materials and it is no longer that crumbly felt backed plastic. It is a fibrous, formed material that looks like it would deform if it took a hit vs. shattering. I do run a GTS lip so I'm sure it disrupts the aero of the stock piece some but the side wheel air directors are still visible and I extended the the leading edge of the cooler outlet to try and get it in the air stream more.
Just dumb stuff I think about.

IDK if you're calling this "dumb stuff" to avoid lighting people up or whatever, but it's absolutely not dumb and you're right to bring it up.

If the effects of the factory design were negligible, they wouldn't have done it that way. A flat piece would have been cheaper.

Everything you're describing is why I'm still on the factory belly pan despite all the well-regarded aftermarket options. There are a few things about this car I'm willing to compromise on, but cooling airflow is not one of them. And if the belly pan is going to incorporate those airflow-related features, I don't want it to be stronger than the far more expensive bumper cover it's attached to.

Maybe a little, but it's mostly just my wandering mind, and obsessive attention to detail, and also why I continue to run the OEM piece and attempt to improve upon it.
I've had this car since 2013 and just recently replaced the original belly pan, it had a good run.

How are you guys attaching the fender liner to the skid plate so the fender liner doesn’t hit the tires?

I drilled 2 holes through the fender liner and the edge on the skid plate and used 2 plastic body panel push pins. They have been secure through probably 10+ track days.

Yup not an issue for attachment.
Been running an AL skid plate [local fabricator] for ~ 4yrs/15K mls with a very lowered whip...saved "my bacon" when ran over road debris at highway speeds

I’m going to be very direct here based on my background in engineering: this undertray has so many obvious design flaws that I honestly hope it never reaches a customer in its current form.

First, it is pretty clear this is a Made-in-China private-label piece. I started seeing these same undertrays showing up on Alibaba, so it was only a matter of time before a U.S. vendor put their logo on one and tried to pass it off as their own product.

And to be clear, I am not against overseas manufacturing just for the sake of it. Not at all. I care about design, function, and quality. I’ve run products on my own cars that were made overseas. That is not the issue here.

The real issue is launching a product with what appears to be little to no actual design validation, research, or platform-specific development behind it. That is just careless.

So I have a few very basic questions:

How are the fender liners supposed to mount?

How is the front of the tray supposed to secure properly to the bumper?

What testing or development data do you have showing this design was actually engineered for the platform?

The grille design is also poorly executed. If your goal was to replicate the OEM-style airflow management that helps extract hot air from the engine bay, this does not appear to do that properly at all.

I do not know much about your company, so I am only judging what is in front of me. And based on that, my honest opinion is this product should not be released in its current form. Go back to the drawing board, fix the design properly, validate it, and then bring it to market.
