I've gotten a few PMs about the hub stands, so I wanted to post a few more details here:
The ones I am using are the
Accu-lign from Tanner by Mittler Brothers:
https://www.mittlerbros.com/tanner-by-mittler/acculign-alignment-system/acculign-alignment-system.html
It comes with 3 hub patterns, and I think mine has Porsche 5x130, Toyota, and Honda (the person I bought them from had a Cayman and an S2000)
I like that it has the rollers at the bottom but due to the big square profile it requires spacers to clear the caliper. On my 2000 S, I have a 7 mm spacer in the back, and a 20mm in the front (I think I could have gotten away with 13-14 but these 200mm spacers came up one sale and so I grabbed them). Since I have long studs this worked out OK for me, folks with regular lug bolts would need new longer bolts to go with the spacers with would add some expense.
The include toe sticks only give a span of 15", I would like longer and I will probably get some made at some point.
For the rollers I bought four 12x12x1/16" steel plate, and bough a sheet of 5/8 plywood cut into 12x12 squares and a bunch of 12x12 vinyl floor tiles to use for shims.
The instructions for the stands include directions for a water level, which is what I used to level the stands.
Flyin Miata Hubstands made by Paco Motorsports
If I had bought the stands new, I think I would have gotten these. Turns out, shortly after I bought the ones I did, they released a new version of the these stands:

They have longer toe sticks and the toe sticks have markings you can use to align with the strings.

These look nice but are $$$
The digital camber gauge they sell looks to be this one:

I tried several other digital angle gauges, and to me, this one was the best.

These are relatively new, and they have been through several designs - an initial criticism was that there was no "pivot" capability to deal with different camber settings, these would sit flat on the floor and folks were worried it would stress things out. So now they have added a "camber rocker" which is a piece that goes on the bottom to let it pivot. Other suggestions were to put it on a thick rubber mat, or things like that. These have the lowest price. The latest design wasn't out when I got my hubstands, but even if it had, i think the flyin miata/paco motorsports stands would still be my first choice.
There are probably some others out there, but these are the ones I looked at
