Really makes the sound pop with minimal effort for the mod, easy S tier
Boba U4T spring swapped to Thic Thock 67g extended springs, Tribosys 3203 bottom housing, spring, stem housing, Keyboard Kustom PE foam, with ~2 layer gaffer tape mod
Gives spacebar a marbley sound, makes tactile switches feel amazing on the bottom out, gives stablizer keys nice thocc, and generally improves all the single key sounds. For such an easy add-in you can't go wrong with this.
