NOT A TA

For anyone following along who might wonder why the rotors are directional it's because high quality brake rotors like these have curved vanes inside the rotors ( instead of straight like many stock ones) that pull air from the center of the rotor hat through the middle of the rotor while rotating. It's really only needed when braking hard repeatedly like on an auto X , road course or spirited driving like a canyon run.
They're more concerned about the calipers because the pistons are different sizes on the high quality multi piston brakes so the forward part of the brake shoe has more pressure to avoid squealing or chattering. As the pads wear you'll notice a taper to the pads with the forward edge being worn more.
