If you want responsiveness, start changing all that shitty bushings our car have.
My Fiat Panda has stiffer bushings.

As for toe, just re-read your original post, IMO 0.1 degrees total rear toe would be fine but I don't think you'll notice any kind of profound change really.
That's been my experience with this car, I've run both 0 and 0.1deg.
On other cars with heim joints and aluminum/delrin bushings, I've found too much rear toe (in excess of 0.3 degrees) to suck, bad, for everything, but 0 to 0.1 even 0.15 degrees no probs...
Losing grip suddenly and not progressively can be a characteristic of how the tire grips. Some tires have a lot of latent grip after wheelspin or sliding begins, and some have less. MPSS I had on the FD RX-7 were kind of the worst in this regard after 2 years on them, any amount of wheelspin and they instantly lost all lateral grip. Not progressive at all...
Dunno what you can get for more trackworthy tires, but you might consider something like RE71R, A052, RT660, ZIIIor if Michelin is preferred, Pilot Sport Cup 2?
RE bushings, I havent done much with my BRZ there, just polyurethane inserts for the rear subframe, which helped a bit with left/right transitions. Pretty happy with it as it is for street/track at the moment but may get poly front control arm bushings before next track season...
