I just wanted to know how this works because it looks like I will be designing one in the future for our school's Formula car. Is the cable stiff enough so that it can be used to adjust the bar in both dircetions?

The effective range of a bladed sway bar arm is 90º. It provides the most torsional stiffness in the vertical position (12 o'clock) as seen in the above photos, and least stiff when the arm rotates 90º from vertical to 9 or 3 o'clock.
In F1 racing where a couple of millimeters of suspension adjustment is huge, the cockpit camera sometimes catches drivers changing the roll stiffness with their cockpit controls at specific corners to maximize entry/exit speeds. There's a difference of opinion on driver-selectable roll stiffness in lesser forms of racing. Some remove the driver temptation to fiddle by installing the adjustment lever out of reach. I saw one pro Porsche Cup car with the front/rear SB adjusters in the trunk.
