These only work with aftermarket rotors with directional air flow correct?
Just curious, what are the principle differences between this kit and the DIY brake cooling project some of us do? See:
DIY - Brake Cooling Ducts
I was hoping for something that doesn't utilize the fang vents as I was hoping to duct air into my Gen 3's from there. Can't get a Stillen fascia either because I already bought a Stillen splitter + canards..
