I finished installing the KW HAS kit. I still have to take it out for a test drive but thoughts so far:
In order adjust the rear height I have to take a couple bolts out to relieve ALL pressure from the spring (the threaded part just spins with the collar). Dumb design. They should have made it able to be held by another wrench
For the front, the adjustable KW collar/sway bar holder is a real pain to get on. You have to pound the dickens out of it to get it down to the 2.99" mark. I used a 36mm socket to sit the strut into so I didn't damage the nub at the bottom and used the oem sway bar holder and hammer to knock it down.
Onto the test drive..
