The bounciness improves when I removed nearly all preload, just enough tension to keep the springs from spinning freely
but still wasn’t perfect
I agree I think together we can find the solution, my best idea so far is yellowspeed front coilovers and strutmasters in the rear WITH upgraded/firmer springs on the rear strutmasters. This is the best of all worlds but unfortunately you’ll need to buy two kits

Just wanted to provide an update after about a month of driving on the yellowspeed coilovers. I do now feel the bounce in the rear. It’s not that bad for me but it’s unbecoming of a car of this caliber. I do have some tricks up my sleeve in my quest to make this thing handle as I intend. Did some spring rate calculations based on a formula used by Ridetech. I’ll be purchasing some rear springs and swapping them out. Also had some custom adjustable A arms made to correct front camber (issue for those using W220 lower control arms to mount front sway bar). Also found adjustable rear arm to allow for toe and camber adjustments in the rear. Fronts use polyurethane bushing which should help to further tighten things up. I keep you all updated.

one downside to the w220 control arms/added stability is that the steering feels a bit more stiff/more work to turn the steering wheel
keep us updated on the spring rate situation... I’m of the belief the rear bounce probably can’t be dialed out in shock or spring settings, but would be very pleased to find out otherwise

the changes In geometry of the w220 airmatic control arms will make the car more stable. I haven’t installed a front sway bar yet but even with just the w220 control arms I noticed a difference. The strut mounts to the control arm in a slightly different spot as most of you should recall

Try tightening your preload 2 or 3 rotations. Yellowspeed says not to adjust the preload and that it’s already set but I can confirm that in my case that wasn’t the case. Was getting clunking from the front end. Tighten all suspension components 2x before adjusting the preload. Clunking gone.
