: : Stick with the stock e12 calipers if you can. They are four piston calipers and are about the best you are going to do.
As noted by W., the E28 M5 has 4-piston calipers very similar to those on our cars. The only reason to install them on an E12 is to get the M5 rotor (larger diameter & thicker) onto our cars. I think all that's needed is a custom-made bracket.
