Changing struts/shocks on a Porsche Boxster - YouTube
For the rear, I marked the eccentric bolts with a sharpie & un-bolted the pickup points at the chasis, which was pretty easy. Bolting it back up, I got the sharpie marks as close as possible and drove straight to an alignment shop.
A couple tips with the k-sports -
* Measure the base to bottom collar distance and set it equally on each. Start high, as the first strut I installed was set to 'slammed'
* Make sure the camber plate bolts are TIGHT. Mine were not.
* I used the out-of-the-box camber plate settings and set the strut top bolts all the way inboard, which was a good starting point & required little adjustment during alignment to get me to 2* of front camber.
