Add a rear swaybar, and you should be pretty happy.
"Streetable" is relative. Right now, I think my car is uncomfortable and awkward on the street. It's too stiff, bouncy, and creaky. But, it handles GREAT! I think the big difference from the initial setup is that I put even stiffer springs on the front back in December, and then lowered the car another 1.5" after watching my co-driver get about 8" of air under both of the right side tires. It's a lot more stable now, and I'm less nervous autocrossing it. But, I've decided that I'll never fully trust this car, and never drive it to 100% unless I go FULL race car with it... which I'm not going to do.
I'm retiring my Mirage from autocross duty next month. (bought another Miata to play with) At that time, I'll probably raise it up an inch, put the softer front springs on the front, do what I need to do to fit a smaller set of wheels and tires (I bought a set of 15x6.5 wheels w/ 185 tires), and just generally tweak it for better street manners vs. its current autocross-optimization.
