SC430 Suspension redo
I know there are many threads, please point me to one-search didn't go well.
Would like to update suspension of 2007 SC430 with around 64k on it.
Is there a complete list of items to replace and consensus vendors/parts to use? (MeisterR Zeta?)
Not looking at esoteric but best bang for the buck stuff.
Would also appreciate any help in a backseat conversion to luggage area.
Wanting to redo 3 things, back seat, apple carplay addition, suspension.

So is there a consensus Sway Bar front and back or a mix?
My goal is to take the slop out of the handling, I'm not looking to track the car but want a comfortable ride without the slop.
I know I need new bushing, I won't be doing any of the work, but while its up getting some done-might as well get all suspension work done. All suggestions are gratefully accepted as suspensions are NOT my thing.

Meaning a lot of us have gone through a lot of research and time to work on how to get a supple/firm ride car.
still not totally there BTW. I suspect the basic design of the independent four wheel suspension may be flawed. Arms too short? Wrong angles? Wrong arm design?
Versus hung between the wheels feel like a jag it feels like you are on top of the suspension. Hard to explain.
Some of the parts we or i have bought and installed are not readily available due to the age of these cars and the low production volume.
My current setup has the MeisterR’s CRD with Jerricks selection of 12 and 6 rate springs as oem but shorter. Shorter is stiffer.
Some here have removed the 18” rims and went to 17” rims with taller sidewall tires for better ride quality. Ongoing issue.
i went to a better ride quality lower noise better steering 45 series Michelin tire to give away some of the handling in search of plush and firm with no bod roll.
at 33 psi the tire rollover is noticeable when cranked hard in canted off ramps. So do i run 36 psi and lose some ride quality? How much hard turning versus straight ahead driving?
i live in south Orange County California and the freeways here have hard straight across seams. If you have nicer smooth roads you can setup your car differently?
to redo another sc430 06-2010 i would start with the MeisterR’s CRD to start with. It’s possible that the best ride control may well be the more expensive MeisterR’s with the separate compression and rebound adjusters not ganged together.
Spending another $2k to test the idea is possible but not at the top of the list.
Would love to drive one with the more adjustable suspension some day.
the sway bars tend to stiffen any cars ride. Hence the shocks first versus my way with the sway bars first.

There are so many posts regarding all your questions already. You just need to do some searching. You'll get your answers much faster that way.

Do you need to lower your car? If not, do the rear sway bar (ISF) upgrade first to see how you like it and then more upgrade.
You can do it yourself in a couple hours as well.

i went that way so I have no info on just doing the shocks first.
as I have posted here the oem shocks on both our 08 ls460 and the 08 sc430 had similar dampening profiles.
Too much high speed compression dampening and too little low speed compression.
bottoms on dips badly. Deflects on sharp edges.
Did you not notice?
Readjusted my MeisterR CRD’s today. Went to 12 in from full soft versus 10. Too stiff. At ten the car was bouncing on the freeway from not correct wheel fit to the front hubs.
shimmy and shake at 65-70.
Went back one click to 11 in from full soft. . Ah just right. Plush and firm. Dampened out the suspension shakes.
Sensitive adjustments.
