you're going to have to go after market, Ie Stop-tech,Brembo,Black label,Project mu,Rotora.
if you want to say, on the Honda side of things, you can get calipers from an early model Legend, or Nsx. you're going to have to get matching rotors, but you need to get them re drilled to 4x100, A company sell's re drilled calipers but i forgot the name of the company. For the rear you can upgrade to ep3 si brakes but you need to swap the calipers from left to right. the rotors from the ep3 4 lug are a direct bolt on. check out honda tech or g2ic to get some more info.
