Rotor Design:

Our unique and patented rotor designs make our discs cooler and last longer.

1. Convergent vane design
   
   The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler. (Illustration #1)
   
   
   
   
   
   
    
2. Center-mount design
   
   The center-mount flanges for hat mounting to the rotor ring have several benefits. (Illustration #2)
   • It allows the ring to be used on either side of the vehicle simply by mounting the hat on either side of the ring (unidirectional).
   • The stress load transferred from the ring to the hat is balanced.
   • Air inlets are widely open to both inboard and outboard sides of the rotor. More air suctions and even temperature on both sides of the disc surface.
   • Heat transfer from the disc surfaces to the hat is even and minimized by increasing the flange length and the airflow around the flanges.
   • Mounting flanges are on both friction surfaces ultimately provides excellent heat balance.
3. True floating design
   
   Exclusive full floating design with 10.9 grade alloyed hardware. Hardware is DACRO coated and crimp locking. DACRO is highly corrosion resistant and provides a film for easier movement between the hat and rotor ring as disc expands and contracts and the crimp design provides positive engagement without rattling or torque loss at temperature.
