(one tire locks up under hard breaking and i have no clue why except for the bad suspension design)
Is it capable of locking all four but one just does it prematurely, or is it only able to lock one at all?

Have you investigated whether it's coming from geometry, bushings, or some combination of both? Things like articulating the suspension in the garage to see how much of what you observed is occurring with unloaded bushings, also a laser point taped to the tire and projected on a wall would let you more visibly see an exaggeration of the bump steer arc. Also you could take measurements (ideally both sides to see how close they are to identical) as it sits on the ground, and run the current geometry through a suspension analysis program?

...is there a way to prevent this without using stiffer springs and keeping the rubber bushings? I assume the only really thing to do is to design in anti-dive or compression adjustable shocks...
If it's coming from the bushings, urethane bushings or spherical joints? If it's coming from the geometry, adjust the steering rack and/or tie rod end positions to minimize bump steer?
