So, I started looking around and still EVERYWHERE I look I see only one diameter of the center hub on Lexus/Toyota vehicles: 60mm. (or 60.1mm or even 60.08mm - close enough).
Here is one thread where a guy goes to his shop where he had one 2gen hub and measured it himself and found that it was 60mm:

And then, if one searches for hub centric rings, they ALL come in one size only for lexus and toyota and that is 60.1mm ID (inner diameter).
However, just as I thought that I got this finally figured out, I found images of the 2nd gen LS hub:

And it seems that while the hub diameter is 60.1mm, there is an extra "meat" around the place where disks goes, making that part about 2mm wider...
Why did they have to do that?????????? Are those 2mm really helping with anything???

The whole rotor has increased in size. I imagine the engineer had a pretty good reason. Will a gen 2 flange work? Might be easier than trying to put a spacer in that hub.

i don't think buying centering rings will remedy this issue overall. the inner diameter and offset of the rotor look like they differ from the pics i attached. you can make it work but it will not be ideal. meaning you can back out the brake shoe more so there is less drag however the brake shoe might not be fully contacting the rotor at the appropriate spot causing more issues down the line. just something to consider, but of course i know you wouldn't want to toss the brembo rotors...

in addition to the hub, you need to measure the ID of the rotors where the parking brake shoes go, i believe the 2LS ones are slightly smaller.

Yeah, I'm curious what the difference is. I just checked the spec for my 98. It's 190mm or 7.48 inches.

I checked that before ordering them, they are all 190mm, standard size, so at least that part is OK.

Not only that but I am really getting wicked good braking power with this setup, don't want to waste that either. Not to mention SS lines in the back, which are not compatible with old calipers (can you believe that on 1990 LS, brake line screws directly into the caliper? No screws, the line itself is threaded! What idiot came up with that idea? That means that once you screw on the line, good like trying not to put any torque on it as you are placing it on the wheel...)

I think I will just use a 1mm bent piece of aluminum or steel and wrap it around that area of the hub and that should do the trick. If anyone has small piece of 1mm sheet metal lying around let me know

I thought of that too, but each hub is around $50.00, and it seems to be labor intensive - probably as hard to do as changing the wheel bearing.
