Okay, I had the exact same issue under the exact same conditions recently.
Installed new rears (Primewell, cheapo brand) but kept my 50% tread Michelins on the front. Immediately super twitchy with snap oversteer. Downright scary to drive on the highway. After a few hundred miles of wear-in the instability softened quite a bit. Then I put new matching Primewell tires on the front and the problem went away completely. Back to a rock solid beast.
From my experience these cars seem to be hyper-sensitive to two things: Thin tires and mismatched tires.
