I love this foam combo. I ordered the foam in white to put on my INK Black Polycarbonate KBD67. It definitely enhanced the sound and feel of the board compared to what it was like stock. I had to make small cutouts in the plate foam to fit around my Durock screw-in stabilizers, but that was fairly easy to do. Once I made the cutouts, it allowed the foam to sit flush between the PCB and plate. The fit is initially super tight, but the foam compresses. This was my first time ordering MK Ultra foam and I am super impressed. I will definitely order again for future builds.
