First test fitment, need some help/advice.
I had a bit of time to test-fit my new wheels on the front.
My current setup is the stock IPL wheels with 20mm front and 25mm rear spacers (bolt on). That's an 8.5" wheel front, 23mm effective offset, and a 9" wheel with a 20mm effective offset.
My new wheels are 19x9.5" with a 45mm offset. TONS of caliper clearance. Like more than a finger, with NO spacer. These wheels would most likely clear every big brake kit out on the market for the G37.
With no spacer and no tire on the wheel, the front wheel inner clearance between the edge of the rim and the portion of the lower control arm that meets the upper is less than a finger width. It almost looks like, with a tire, it would rub but the arm continues to arc out as it goes up. I'll be using a 255/40 which is 27.1" tall (26.9 is OEM tire height). It's not so much the height as it approaches the upper control arm ball joint as it is the width.
QUESTION ONE: How much inner clearance do I need? (see photos). It's a little tough to tell as the rim is black.
So why don't I just add spacers and call it a day? Well I did a test fit with the 20mm spacers (25mm effective offset) and felt they stuck out way too far for my tastes. It's also hard to gauge with no tire and the suspension drooping but this gives you a rough idea.
I then tried the 10mm and encountered another issue I'll get to in a moment, which brought me back to no spacer and what looks to be a flush fitment but with inner wheel clearance questions.
The 10mm spacers are hub centric. I'm using adapter rings to go from 73mm to 66.1mm for the wheels. Yep, the inner lip of the hub centric fitting on the spacer has it's own flared out section towards the base. So the spacer doesn't sit flush and it looks like when I put the wheel on, it too, doesn't sit flat against the spacer. No bueno.
SECOND QUESTON: Is there another high quality bolt-on (not extended stud) wheel spacer in the 10mm size that's hub centric and does not flare out at the base? The ones I have are FIC brand, made in Japan.
Here you can see the hub centric ring on the spacer and the gap between the spacer face and the bottom of the hub centric ring.
No hub centric ring, noticed the beveled bottom edge as the spacer's hub centric meets the face of the spacer.
THIRD QUESTION: (I think I know the answer to this) Is it possible to use a spacer, say 3-5mm, without extended studs on our cars? Is there enough fudge factor in the stud length to do this? I believe I read we have about 5mm extra on the OEM studs via the370z forum.
A few more questions to come and thanks in advance for any help/guidance!

Ape, you'll be ok. Carl (Intricate Detail) had 18x9.5 +45 on his AWD sedan and had about 3/16" clearance (since that knuckle bends outward you'll have even more clearance with a 19" wheel. He ran his hard on the tail of the dragon, if there was any issue he would have found it.
Here's his build if you want to check it, the wheel clearance is somewhere in there w/ a pic.

clearance will be fine with 255, I'd be a little more worried if you were looking at 285+.
You'll be fine running a 5mm spacer with the stock lugs, there is a little extra room...I wouldn't mess with those hubcentric spacers, I never felt comfortable when I ran some.

You need to fit tyres and not have the car on jackstands only then will you get accurate test fit.
