I went up one size on the front, to 245/40 and 265/40, and it works wonders, while retaining a wear-friendly alignment. This is for street use, I don't track the car at this time.

It sounds like you are definitely on the right path with decreasing the front to rear stagger.
Every tire has an ideal camber and pressure for optimum grip, and anything off of this can be used to adjust steer characteristics front to rear, but you should keep in mind that you are compromising ultimate grip for balance when you go that way. As Carroll Smith taught us, it's better to work on making the loose end grip, then trying to "unstick" the end that is working.
In my experience, for most street tires, the total range of pressure adjustment should be around 32 psig - 37 psig. Anything more or less than this is a big compromise in performance.
The alignment advice given above is very good for maximizing the stock suspension. After that, you need GT3 type front arms and sway bars to improve grip and balance. Welcome to the slippery slope...
