I'm not building a car around PT/TT but if it comes to the region I would run it for fun. Which is why I would want the NASA legal version. I have the group buy version, which means I would have to upgrade at some point.
Are the normal offset bushings +2 also?

Offset bushings are no points as long as they are not metallic. So delrin, poly, rubber, etc.

Depends upon your ride height. It all works together. The lower the car, the more negative camber you will "naturally" have due to the double wishbone suspension.
These are best used on track cars where the extra negative camber is needed. In my case, I need about 0.5 degrees more negative for my front tires to be happy. Not a setup I would drive on the street though.

If you looked at the camber adjustments from you'd see that the left and right are not exactly the same, because every 20 year old car has had its suspension tweaked in one way or another. Ride height, set-up, accidents, flexy a-arms etceteras are all going to affect your camber rates. Min/max may not be the same.

The new ball joint will shift your current adjustment range about another -2 degrees. If you were able get a max of -2.5 before you can now get a max of -4.5
The range of adjustment on all Miata's is about 2.5 to 3 degrees. Where you fall in that range varies by ride height, NA vs NB and all sorts of other little variables from manufacturing tolerances to impact damage.
At my ride height I max out at -3 degrees. That means my adjustment range is -.5 to -3. degrees. With these new ball joints the new range is -2.5 to -5 degrees. This will allow me to raise the car slightly (it's slammed to get better camber) and get the -3.5 I am looking for with great castor numbers.
Hope that helps. The actual figures above may be slightly off but you get the idea.
