While I like the business concept of up-market "commodity" suspension components (and gratuitous engineering jargon)... the discerning customer might notice that the "Western-educated engineers" learned much from their travels.

Penske make excellent suspension components, and they're also a supporter of our community (with R&D and forum discussion). That a resized version of their piston design. They also use Silkolene RSF. Plenty of materials are similar between your designs, too.

The differences are interesting too. I like the durability choices of Viton (FKM) o-rings and ceramic piston rings. As long as your machining tolerances are tight, these can both work well. Even with that Kashifuji 6-axis CNC, it's not easy to get it right. If your engineers haven't read the Parker Seals Handbook, it's got excellent design guidelines for o-rings.

I also like the spring rate strategy, which is just stiffer than the TRD springs. Travel may limited, if the shock bodies are similar to BC Racing's. We shall see.

As a side note, 250 hours of ASTM B 117 is a nice marketing strategy... but that's overkill. It's a good QC check for pinholes, but sacrificial coatings (like ZnCrO4) are best evaluated with a cyclic salt fog tests. Either way, congrats on passing it!
