Let's Talk About (Miata) Ladder Bars
So my Miata, like many others, suffers from abysmal wheelhop upon even soft launches. I've done a fair amount of digging and seen people have had various levels of success mitigating said wheelhop by slipping the clutch heavily, or by replacing the upper/lower A arm bushings with delrin/poly bushings, as well as suspension changes and moving to drag slicks.
I am already on aftermarket suspension and SADFAB bushings are still on multi-month backorders. Drag slicks are not an option for me. Hillclimbs and AutoX are where this issue crops up and my entire rear end sounds like it's going to assplode untill I lift or it hooks 100ft later. I'm insanely jellious of TNTUBA's ability to do burnouts/launches with a rock solid rear.
Has anyone attempted ladder bar like additions to the lower A arms in an effort to alleviate wheelhop? In my searches I have come across only one photo of Miata suspension with something that matches what I have in my head:
Obviously this requires a bit of fab work, but doesn't look too complex for an average Joe armed with a welder and tape measure.
So my primary questions: Does this work? Is it worth the effort? Is there a flaw in the design above I'm failing to see? Am I chasing dreams of a smooth launching Miata, and I'm just doomed to break diffs as often as I break necks?

Have you considered getting rid of the bar that attaches the transmission to the rear end?
If not, you might consider doing that and supporting the rear end in the same manner that the V8 conversions do.
Here is my reasoning.
My car has a V8 conversion putting 315 HP to the rear wheels and stupid amounts of low rpm torque.
My car does not have rear wheel hop and gets really good traction even when I dump the clutch and do a hard launch.
Don't get me wrong, you can make the rear tires break loose if you do your best
but
it is very difficult to get it to break loose and it just spins the tires in a nice controllable manner until things settle down and the car launches very nicely.

Increasing damping in the rear seems to have a huge effect on wheel hop for me. Is it possible that your worn out Tein's aren't doing as much damping as you think? Upgrading to 441 or similar would mitigate wheel hop as well as improve overall handling. Seems like the ladder-bar idea is kind of a band aid.
