Although not always necessary, the rings can help center the wheels during install. Also, I assume that you have the correct type of lug nuts for your wheels.

That was something else I thought of! Only thing I was thinking... was if it was hub rings it would do it with or without the HC spacers. And I don't remember my car juddering a month ago when I installed spacers or before. Just within the last couple weeks. Seeing as how the spacers are hub centric 66.1 just like the OEM Nissan hub (bore). But for like $10 a set, it wouldn’t hurt to try. Most I can rule out right now is wheels are balanced issue, struts / coil overs check out fine and alignment is good since it was done maybe a month ago and I've not hit any big bumps or done anything to knock it out of whack. I did brake bedding process and will report back tomorrow to see if braking judder has gone away, got better / worse ! Then I’ll pull spacers off front , see if that helps. Maybe try the hub rings see if it works. And if all that doesn’t work I’m gonna get new rotors in a few months and go over braking system, stuck pads, kinked brake lines something. That's about all I know of honestly...

Not saying they may not be warped, just that it would more likely be a direct than something you did.
I'm just all caught up in this, like, "Enquiring minds want to know!". Lol.

I agree! I’ve never had warped rotors. Not even on my sport bikes. And that thing I got way faster on and slowed down a lot faster too. So
The Z should be good but idk. I’m not gonna rule out warped rotors just yet. I did do the 60-10 , 5 Times though! Read my below post to @SouthArk!

I've heard of people using sandpaper to get rid of the glaze but padding is easier (and more fun).

Gotcha! Well okay I did about 5 , 60-10mph brakes on the last one they started to skip while stopping, like ABS was about to kick in so I stopped, got on interstate and drove home 10 or so mins. I had to touch my brakes lightly a couple times but NEVER completely stopped and let the pads sit on rotor. Even when I got home I coasted in driveway and pulled e-brake. I put my hand to rotor on the cooling fin area and it was warm but cool enough to touch so I’m assuming it got it’s good 60-10mph brakes in and properly cooled. So we shall see tomorrow if judder while braking has stopped, got better / worse, etc. Vibration from 65-80 are still there after bedding though just for the record.
