@Dramatic_Hammer pick something to suit from here maybe. They have various different compounds - standard semi metallic/sintered/kevlar and RACE MATRIX
It might need a proper bleed too. Pretty common for hydro brakes to have a shitty bleed from the factory leaving it feeling spongy and lacking power.
A combination of shitty bleed and duff pads or undersized rotors might be the problem.
It would be my first option, yes
