I usually widen my stance on these to make my legs grow all around (not just my quads). This also allows you to get lower and throw up more let. Follow these up with some hardcore Leg Presses, Leg Extensions, and Leg Curls for a complete leg workout.
Keep in mind deadlift also works your hams and lower back so seperate your deadlift and squat days accordingly to avoid overtraining.
Good luck.
