These are the tires I have used for autocrossing:
Toyo FZ4 - suck!
Yokohama A520s - great stick, good wet weather, but loud!
Kumho 712s - good stick, good wet weather, inexpensive
Falken Azenis - great stick, good wet weather, inexpensive
What mods do you have done? You live in Hong Kong and they have SCCA?
If you want maxium traction go for DOT Racing tires: Kumho VictorRacers, Kumho Ecsta V700s
