1998 S70 Are brake vent holes in rotors directional

Post by s70fanman »

I replaced the Brake Rotors on my S70 and noticed left side rotor vent holes on my new Zimmerman 302 mm fronts and matching rear Brake Rotors are not in the direction of rotation, as the ones on the right seem to go in the direction of rotation. I think that pattern of holes for ventilation on a Brake Rotor should follow the Direction the Direction of Rotation, but would love to hear other peoples Opinion.

Thanx-S70fanman
