see_fu's doing a legend caliper transplant, which comes with 2 pistons instead of the single piston stock calipers. however, this mod requires you to mount the calipers backwards (leftside to right, and rightside to left) so that the bleeder valve is at the right position. at least that is what he tells me.

you can then upgrade to prelude rotors, which are just a big bigger in diameter over the accord.
