Brake Calipers

[cherrington17]

Now, i know dual piston give better stopping power then single. but what if the single is larger then the dual? I assume dual is still better since its pressing on each side of the pad, rather then just the center?

i just did a basic brake job on my mom's 2000 mustang, and noticed her caliper is pretty much the same as ours, but has 2 pistons in it. Its pretty well known that we can swap calipers with other cars, but you require bigger wheels to do it (17" at least, if i remember) but are there any smaller cars that might have 2 piston brakes that would mount up on ours? (i'd love to have better braking w/o having to make a major investment like new wheels) the mustang's looked pretty damn close, but i bet there is something i'm not seeing that would prevent it.
