s14 rear caliper upgrades

[Fancy_Footwork]

I've done a couple searches, to no avail obviously, on what oem calipers can be bolt on upgrades to the s14 rear. I'm trying to find a nissan/infiniti two pot rear caliper that's bolt on for my s14. I've heard of r33 rears on an s15.

Any info is appreciated.

Aren't Q45 rears two piston calipers and a direct bolt-on?

I know q45 fronts are 2 piston direct bolt on, but I doubt the rears are 2 piston as well.
