Help me pick front calipers

i have been doing alot of research on this and i think that i am going to just try the 4 piston wilwoods with the 4" total piston area and see what happens. this is the cheapest way to go as the calipers only cost $140 ea. this will get my car rolling for the time being and i can always up grade later. they have to at least work better than my factory 9" drums did.
