Hello, I'm Jason. I will do my best to answer your question quickly and accurately using the information you have provided.
Ok, so just trying to get this all straight. You have the coilover setup already assembled with the top mount in place, correct?
I've done lots of these conversions (although not with the Blau setup), and no compression is ever necessary
The lower perch on the shock is in place?
yep, totally understand what you're saying
So yours came assembled, just like they look on the left in this pic?
Ok, so if you remove the u-shaped swaybar link, and loosen the inner bolt that holds the forward control arm to the subframe, you should get enough downward swing on the arm so you can get the shock on
That inner nut should be a 19, and the bolt head an 18
I believe. Or it's 19-19
Yes, correct. So, when you get both sides assembled, keep all inner control arm bolts slightly loose. Then use a floor jack to raise ...
sorry, UPS just showed up
the bolts I'm speaking of are the ones that hold the control arms to the subframe (lower) and the upper spring mount (upper)
use a floor jack to raise the suspension before tightening the inner bolts completely
this keep you from twisting the bushings out of that car while you drive
