Best way to do it? Front suspension
I'm replacing front shocks, upper and lower ball joints, and now steering rack and sway bar bushings! Might as well!
Question is: I'm waiting on the parts and have drivers side up and apart.
I'm wondering if I should detach calipers on both sides, detaching brake lines, so that it takes stress off the lines and gives me a lot more room to shimmy around under there. Next job will be to change out old brake fluid anyway, just wondering if having them hang open for a few days/week will cause me any problems with master cylinder going dry? Should I cap in some way or just leave em hanging open?

It will be ok to remove.
I'd suggest new brake lines & new seals for the calipers anyway --- very inexpensive and easy to replace.
I've left them disconnected for weeks. Generally I cover with a rubber glove.
Somewhere I read that no special considerations are required for bleeding the early ABS unit, though Nicole and Bill Ball have struggled with her bleeding her later car.
The 86 bled fine for me.
Stringing up works, too, but replacing the old hoses is a real good idea.
Huge improvement and peace of mind with new hoses, caliper seals, rotors and pads. Very strong brakes when all surface area is used efficiently.
Don't forget the front wheel bearings and inner seals when in this deep!

It helps to put your 928 model year and wether 5sp or Auto in your sig.
If a 90 or younger I would take every possible precaution to avoid letting the brake system drain
If an 88 doesn't seem to matter.
I have let both my 88 and then the 90 drain out completely before I knew any better, while changing brake hoses etc. . 88 bled through normally no problems rock solid brake pedal. 90 - mmmmm I have bled at least 5 litres of brake fluid through it normally, reverse bled it (masterbleeder attached to the calipers, fluid removed from mc.) repeat above 2 or three times and still it's not inspiring. You have been warned.

No good reason to leave a brake system open.
You get air up into the ABS controller and you may be in for more fun than you can imagine.
BTW, almost all of the tool truck guys have hooks to hang the calipers, I think they are made by "Leslie" and are cheap, or you can make some out of some stiff wire.

Sorry about that- no MY info
Answers- Control arm bushings look fine. I have yet to look at or play with the bearings. Brake lines I may change out. That seems like it shouldn't be too much problem even after reassembling what I've done so far.
I would like to drive this beast again this year,lol.
I can see that I could go another 500 or so in parts alone before I do everything that can be done in there, lol.
Think I added car info in sig? If not it's an early 86S. VIn ending 0430.
