Sent and email to KYB to see if there were any plans to produce their AGX series (adjustable) for the 5th Gen since they do make an OEM replacement shock/strut.
This was the reply.
Presently there are no plans for AGX fo rthis application. I will send your message along for engineering to read though. They may agree, and proceed with a review.

Figured it wouldn't hurt. Any new product would at least result in a choice, however limited that choice might be, but they do have the specs for the struts and perches since they already make the OEM replacement.
If anyone wanted to do the same, it may show interest which is what we need to get something made.
