Did you install hubentric rings with the aftermarket rims?

Did you install the new wheels and the springs at the very same time? Were the tires brand new or used?

Most member with lowered AWD get the wobble on acceleration so normal and goes away after you reach 20mph. As far as the 75mph shake if your wheels hubs aren't 60.1 hub then a hub ring is needed.

i did install the springs and struts all new, then i put the rims on, also new with new nexon n3000 tires, got an alignment, and balanced the rims, and yes i did put the hub rings on, it still vibrates after the 20mph at the time of acceleration,
