Finally installed my Eibach lift yesterday on my '18 ORP KDSS. I wanted to try to preserve a bit of rake so I modified the kit by using the Wheeler's T13 rear springs, which are made by Eibach anyway.
KDSS is definitely a pain to wrestle with, and I did end up disconnecting the system from the LCAs to get the longer coilovers in. Since I used the Eibach PT front springs (2.75") I set front perches at stock height.
I'm really happy with how it rides and looks, the nosedive is completely gone, and it totally eats uneven pavement and railroad tracks. I'm looking forward to getting it off road. Even without an alignment it tracks totally straight. We'll see if the alignment says I need UCAs but based on the ride I really doubt it...
