It's going to take a long while because the aftermarket companies will need to get their hands on a NSX for fitment and testing which means an owner will need to donate theirs to the cause. But admittedly, that kit does look nice, way cleaner than the pure gas NSX rendering.

For now I can only really imagine seeing splitters, diffusors, lips, and things of such. I wonder who's going to be the owner to send his vehicle off to get chopped up and refitted

I'm sure if you check the well established NSX forums out there and Acura/Honda communities with an NSX sub forum you'll find companies asking.
But it could even be a case of some companies reaching out to owners privately through direct message.

love this pic!!! how do you shoot this??? any technique?
