So How Low Is Too Low?

I've always used keeping the front A-arms parrallel with the ground as a rule. If you look at a Fox/SN95 with stock suspension, that doesn't give you a whole lot of room to drop the car since they are near parrallel to begin with.

The suspension just wasn't designed to be dropped. It's bad enough we are stuck with 1970's tech for a suspension, but then to drop it down, changing all the geometry, and reducing strut travel, and expect to handle well is a stretch.

Actually...correction. handle well on a real-world street, and not a magical, freshly paved road with no potholes and such. That's the key there is picking up all the road imperfections that your average US highway has. Down south, you might have great roads and can get away with a lowered, stiffly sprung Mustang, but up north, those potholes really kill your handling.
