They are selling this kit for $100. It's toe/camber adjustment stuff for an e30. It's an alternative to the eccentric style adjusters that are commonly used.
I don't want to spend $100 for 3/8" stock that has grooves in it.
What's the easiest / cheapest way to do this?
Find a machinist who's willing to make those parts for less than $100?

I should have been more clear. I have access to a milling machine but I'm not sure what the best way is to make grooves like that.
If you have a vertical mill then just do as I did when I made a similar part, . turn the head of the mill to a 45 deg. angle to the table. Then all you need to do is use a standard cutting mill to make the groves. You will need to do determine the depth of the cut and the spacing.
I started with a larger piece of steel and made my groves and then just cut it up to the size and shapes needed.
Is there a reason to avoid the C4 corvette eccentric bolts?
They are cheap and the brackets can be made in minutes on the mill.
I have never used them, but I've heard more than one person say they tend to walk. One said that after a few autocross runs an alignment was needed. That individual opted to spot weld the eccentric to the track after an alignment. Again, I've never used them, just relaying what I've heard.
plenty of cirlcle track suppliers sell the stock but the teeth are also limiting as to can't move a 1/2 tooth.
You could use a 45 deg. end mill.

What is it called? I have no idea what to search for.
"steel bar stock with lots of teeth"

I remember seeing square plates to replace the eccentrics in Mustang lower control arms for track use. They're still drilled off-center, so you could still get four different settings, but there's no way they could rotate.
Yeah, trackie parts for '65-73 Mustangs. The ad was maybe ten-fifteen years ago.
