Ingenieur like estrallajon mentioned probably your springs are not sitting properly or you have a spring pad higher on one side

If thats the process. The swing arm inner bolt does come off I think but maybe not necessary. There is a rubber bushing in that sub frame. That exactly the bolt I torqued pre-loaded. This could a possibility with ingenieurs height issue that's worth checking. So what he's doing by placing on ramps then loosen and tighten basically will help on the pre-loading.

I checked the springs, they are seated properly
Had it on stands with the wheels removed, got a good look
The bottom perch is notched/keyed
I also lubed all bushings/joints
Kind of grasping at straws but something has changed the height
I think the sway bar is the only thing removed for the diff but I could be wrong
It's close to 1/2" difference
Car rides and handles fine

Air tools speed up work progress tremendously but not necessary. What's required are All metric type sockets, wrenches, including E* star bolts. Invest in a breaker bar if you don't have a heavy duty impact wrench. A must in my opinion is a safe strut spring compressor. I had my share of cheap way of compressing springs. Very dangerous and takes forever. I figured I only have so many chances before I lose any eye or a jaw. :-/

Put it on ramps
Pulled the plastic lower arm covers
Loosened sway bar upper/lower bolts
Upper was a single std head
Lower had a E torx and std
Jostled the car and it settled 3/8 " or so
Tighted it back down
Bar must have had some pre-tension?

Hmm possibly. Interesting that the sway bar would have tension. Are you talking about adjusting the sway bar end links right?

Finally got the rears done. Took longer due to the exhaust had to be moved so I can remove the essentric bolt. I flipped it going back in so I don't have to deal with it next time. 
Dunno, took me like 3-4 hours. 
Would have taken me longer if the little one didn't help

I think you are correct. After looking it seems like the inside lca was dropped. It has a internal 12 point on one side and a 18 mm hex on the other.
This makes me think springs aren't seated properly .
Any pics of how it should go?
Which is the top of the spring
Hows it sit in the bottom
Etc
I know on the e46 it looked like the end of the coil should butt the perch step/shoulder but if you did that it could not unwind/expand properly under load...you 'ld leave 1/2" or so per the manual
Mine looks butted up against the shoulder

Exactly . The end of the spring should butt up against the swing arm perches. Had an E46 as one of my cars that I worked on everything. Much easier to work on btw compared to our cars now. Our cars is like working on E9x cars. Takes much longer but doable.

Ha. Yeah. Juggling the little one and car projects, adds time. I will take pics as soon as I get it settled and drive for 50 miles.
Btw, rear adjustments on these cars are impossible and will need to redo the whole process all over again . The adjustment perches are unreachable once everything is buttoned up.
I will post picks and let you know how many turns I did from maximum lowest adjustment.

So perhaps the top is not fully in the pad
I'll jack it up tomorrow and take another look
Thnx

The rubber pad has a slope that hugs the spring. These will only move if the spring is disturbed like Moving the swing arm down

There is a rubber pad on top which the spring end sits on.

I'd wager the top is misaligned
What are the chances of getting a screw/hook compressor in there to relieve tension and spin the pad
Otherwise drop the arm and sort it out

I think dropping the arm is the only way to ensure the spring is seated on the pad. We can't really twist them due to the bottom being secured or enough room for a spring compressor. Besides at that point, better to drop the arm.

Ride on the H&R coilovers are different and I have mixed feelings. I like the drop but prefer the P30 ride suspension due it's stiffness. Ride is much smoother on the coilovers and takes bumps better than the P30. Not necessarily better on my part. I'm used to harsh rides I guess.

Definitely not as harsh as the previous P30 stockers. I can't really compare to other C63s. The only other C63 I've driven is a 507. I think the P30 is a bit stiffer.
Who knows. I only have like 10 miles so far. I'm sure once I get used to the ride. I'll change my mind :-)

Yes, that should do it. Depending on the direction the bolts are installed you may need to drop the exhaust. If the bolt heads are facing the rear then drop the exhaust because there will not be room enough to pull them out without hitting the exhaust. GL

And they appear to be situated correctly
No idea what changed ?
1/2" before/after
Could the springs relax that much from hanging unloaded for 24 hours?
I'll post some pics in a minute
The only thing I noticed the springs are reversed
Round end up on one reversed on the other
Don't think it matters
Upper rt side
