If you can muster the camber to run them, Toyo Proxes R1R seem like they could be pretty good street tire (brand new, 140 treadwear autocross tire). Full tread (rain tire) RA-1's or the new R888 (same compound, different tread pattern) if you don't mind running an R-compound on the street. All 3 call for 2.5-5.0 deg of camber.
Keep in mind also that sticky performance tires really don't do very well when cold. If you don't plan to warm them up before you use them (like gunning it on freeway onramps), you're better off with a harder street or all season tire (200-400 treadwear), as they will actually hook up better when cold than a soft race tire, which will just smear itself on the pavement. The Pirelli Pzero Nero M&S I was running before the car went up on jackstands were a pretty grippy, if a little hard all-round (all season) tire that will stand up to abuse fairly well.
Also, at 16 PSI, you're probably past the point where deflating will give you any advantage, and to the point where you're just unevenly loading the contact patch.
