Thanks to lolachampcar for posting all his work on creating upper control arms. I was able to use that design to make upper arms to reduce the rear camber. Goal was as close to -1 degree camber on the rear with SAS at the Standard setting.
1. Started off with the lolachampcar CAD design and tweaked it so it could all be cut on a water jet with no machine work required.
2. Purchased 2 rear suspension integral links to use the bushings so as to not destroy the factory control arms.
3. Modified the CAD design to remove all the lightening holes. And enlarged the bushing holes so the bushing could be pressed in without additional machine work.
4. My first pass made the arms using the spec of plus .211 inches from the design on his page.
5. With the added length of .211 inches the camber with SAS on standard went to .5 degrees negative. Which was too little. Went back to the CAD design and shortened the bar this gave me the camber setting I was wanting.
Attached are images of the final control arms made out of 1" 6061-T651 bar aluminum cut on a Waterjet, my final alignment spec. I am going to pull out some of the toe on the rear even though I am within Tesla spec.

is this a 1 time project or do you think you might try to market these?
I was pretty close to pulling the trigger on the native links https://n2itive.me/ but I looked at the rear 19” Michelin’s and it is actually pretty good.
