Installed the rears today. It was really easy. Took me a few hours. I even cleaned and painted the trailing arms to make Andy happy.
The test drive proved the value of this system once again. It was definitely noticeable. The front end (still rubber) HITS bumps, while the rear GLIDES over them. And I have Koni's up front and KYBs in the rear.
There are still a few aspects to check out before they become available, but things are looking good so far.
