The Infinity boards were from a before time when discussion for stabilizers revolved around Costar vs Cherry. The Infinity Ergodox was designed with Costar stabilizers.
It is possible to mod the Infinity Ergodox to use the Phantom stabilizers - but you'd need new plates cut. it's definitely a very advanced "mod" if you can even call it that.
Do these require lube to sound decent, or are they good to go out of the box? I'm not really looking for something to match the quality of screw in stabs, just a hassle free upgrade for plate mount-only boards.
