Thanks Brad.
I called FA and THM.
Neither were have encountered ABS line routing issues.
The FA TS person had mostly generic answers and probably was not directly familiar with G37 installs. But he was helpful and willing to check with an installer.
Neither had any insight on extender installs for coupes. I'll remove the seats and see if I can throw an eye on the shock mount dome but so far it looks like it was directly beneath the window w/o room for an extender. But it was late and I was tired. THM offered shorter extenders. I need to see what room there is if any.
As for the rear spring config, THM suggests reusing the lower OEM spring cushion in the spring bucket. It's thick. Like 2" or more.
I put it in on the rear passenger side last night and was able to get OEM height and more. Plus the large metal spring adapter that comes with the FA500s seats directly on it. So I think this will make for a quieter and more comfortable ride. It should absorb a lot of road vibrations and eliminate chatter if any were to occur. Plus I'm not a fan of the metal on metal contact that using only the chunk adapter. THM said the user could go either way but feels it better to use it for street installs. That seem sensible.
I also would imagine if you needed to slam the rear end, you could take it out for the deepest drop.
As for adjusting the rear height and preload, they both confirmed set the height with the spring perch. (wheels off, support the lower control arm.) I found it helpful to unbolt the shock. I think probably the shock top is easier to unbolt than the bottom. Then add minimal preload by jacking up the lower control arm and then adjust the shock length to meet that position.
Hopefully I still have enough energy after work today for yet another evening under the car. I still have to do the rear driver side... then adjust the height all around.
With luck, and perseverance I can drive to work tomorrow and get the alignment done.
I may not do the extenders until the weekend. I think that'll be best done while fresh, not rushed and in the daylight.

It would be my preference to route them into the trunk, but from first glance, it looks like the shock dome is under deck beneath the rear window. It'll be a tight bend to get back to the trunk from there
But I have to climb back there to confirm if this is the case.

Well, allrightie then.
Another late-night wrenching and the last corner is complete.
The car made it through the 1hr commute w/o issue.
I'll drop it off at the alignment shop down the block and button this thing up. As it stands, each wheel is probably pointing in it's own private direction, but at least no warning lights or burning smells.
I calculated where to set the rears and when I put it on the ground it hit the mark exactly. A quick test drive settled it almost half an inch below that point. The fronts didn't change at all.
I figure even when I get the alignment done today, if I dial in a +1/4" in the rear and -1/4" in the front I should not need to get it redone.
I've found adjusting the height on the rears easier than I expected.
Man it feels STRANGE sitting 2+" lower than before!

Just saying.
You're probably fine.

Not for nothing, but those wheels look so much better without that goofy star in the center cap.

So I had the alignment done.
i definitely will raise the back a quarter and drop the front the same amount. That should make both ends even. Side to side they are surprisingly dead on with the opposing wheel.
The shop struggled with the rear passenger wheel. They couldn't get enough toe even with the mods. They eventually got close with a combo of toe and camber adjustments.
I'll take it to an alignment specialist later.
The ride:
With the F & R done, the car rides like OEM on smooth flowy roads and highways. On choppy roads it's more like my old Vette okay, a bit better.
Noise: almost none. I do get a spring ping on the RR but only on very specific circumstances. I'm still trying to figure out what those circumstances are. For 99% they are dead silent. We'll see in s week.
One small thing bothers me is it occilates very slightly, 2-3 times, On abrupt stops at any speed. I think it might be due to having the tear dampers too soft. (5 clicks) I'll tweak it and see.
I still don't see a practical exit point for extenders on the rear shocks. Kinda surprised no one here has mentioned putting them on a coupe yet.

Lol John, I didn't even notice the missing stars, so that means the wheels are blending now, looking good that way Zilla. I think those center caps above wouldn't be a plus.
Just a solid black cap or a black cap w/ Infinti logo would look good IMO, maybe a matching red Infiniti logo on a black cap FTW

The lug area is very rough, and has 10 lug holes.
I'm not yet sure it isn't a bigger eyesore, then there is the center axle nut ring. It'll take time to find something to fit there.
I'll be dipping the star black for now, until I cut a disc that fits over the center and black out the cap bolts. Somebody actually sells the caps that way but I can cover it as well as they can. (The star unbolts)
I got these as placeholders when I got the car and like them enough to keep then until I find the grail set and the funds for them.
With a kid leaving for college, that might be a while. I like these enough to wait.
I saw a set of Niche wheels I thought looked sharp but I hear garage queens are hating on Niche these days...and Vossen, and....

I adjust the fronts and rears to 26.25"
As Brad has so wisely advised, it's the magic number for tread to arch.
I'll see if I can DD it around here. NP with speed bumps or my driveway. I did bottom on something while ballin down my hill and over some whoops at speed.
No marks in the wheel wells.
Looking under the car the pipes have decent clearence. The lower cover looks like it is ~3" off the ground and so does the main crossmember.
Brad I saw your ripped up Y pipes.
That's kinda scary.
Especially considering the crossmember is a lot lower.
