I have 225/60/16 Bridgestone Potenza G009'* on my STE, and for the price they are very nice tires. They are Traction A, Temp A, but they are only H speed rated keeping the cost down, and I think the treadwear is like 420. I ended up getting them for $90 per tire. They stick well, although I still don't have a problem lighting them up.
The SSEi has 235/55/17 Pirelli P Zero Nero'* (or something like that) and I am impressed with those tires a lot. They stick a lot better than the RS-A'*, they are quieter, and they weren't horribly expensive. I believe they are W rated.
My dad has 245/50/16 Goodyear Eagle F1 GS-D3'* on his GTP and they are really sticky tires...the car handles very well, and whereas his Eagle RSA'* would light up anywhere in 1st and partway into second gear, along with giving a chirp on the 1-2 shift, the F1'* don't chirp into second or break loose in 2nd (assuming its smooth dry pavement), although first gear is still useless. I don't think they are worth the $ though.
If you want best possible off the line acceleration, start looking at slicks, but that would get pricey very quickly. If you want best value, start looking at some of the "high-performance" h-rated tires. They can stick well, yet due to the lower speed rating they are cheaper.
