Mixing suspension is a bad idea *Vid added*

I have those same tires.and have the same issue.the sidewall is so soft.I never get them to howl it's turn turn a slight wabble then BAM I'm going slideways.when I was on cheapo Walmart specials(tires that came on car from previous owners) handled better then the v12 did.almost sent me off the mountain on a skyline trip this fall. I'd start with a better alignment and better tires and get some cr rear struts for piece of mind lol.

I'd guess your rear control arm bushings are worn out. Mine is worn out on the right and this bitch gets silly loose turning left
Luckily for all, energy suspension just released there bushing kit!!!!

You guys need to run more pressure in the v12 to make up for a softer sidewall.
I know i didnt like the feel at 35psi(op is running 32psi)... i now run around 40psi front and 39psi rear. feels much better that way imo.
Oh and i dont know why the single ply sidewall things keeps getting tossed around. They are 2 ply. And yes i know...its still soft.

400hp car, 40hp launch 
Espelir spring rates look to be +20% over stock front, +30% rear (5.3/7.0?), shouldn't be a problem for CR/AP1 dampers, but moar stifferer rear => more oversteer. Might try CR dampers in back to match fronts?
You don't have HPS+ pads, you either have HPS or HP+. HPS pads are FAR worse than stock. Not a big deal at autoX, but still, less bite and softer pedal vs. stock isn't ideal, and they will overheat at the slightest hint of serious use. HP+ are decent pads, TONS of bite, but lots of noise and dust. Unless you're tracking the car, OEM pads are fine.
It would be good to see your actual alignment. The stock spec is a HUGE range. If rear toe is at the max end of the range (0.67 degrees total), handling becomes more nonlinear and spooky and tire wear rate becomes ridiculous. General alignment advice for normal to spirited driving: ask for the maximum negative camber and the minimum toe in the spec range.

My mistake, they are the HP+ pads. I corrected the OP
My tire wear is absolutely normal all the way around. Car drives straight as an arrow.

Stiffer front sway bar would probably help. Or you might try disconnecting one of your rear sway bar links at the next autoX and see what that does for you.
