drag radials for 05 si

[SeoulSI]

I have the stock 16's on my si, i want to run drag radials on it this summer because i have the JRSC race kit with the hondata ecu.? I want to take it to the track and i heard that having the perfect size tire will improve times, if so what is a good size to go with with a 16 inch rim?? Also what brand should i go with?
