These two-piece rotors were engineered to be the best stock replacement two-piece rotor on the performance market. This rotor is direct bolt-on, easy to install, no additional hardware needed, and an excellent upgrade for both street and track. Not only will the rotors last 3 times or more longer than competitions' two-piece rotors, they can deliver consistent brake torque under extreme heat, session after session. When it comes to replacement - operating cost over the time will be lower than one-piece rotor.

These rotors measure 340mm in diameter versus OE 345mm. RacingBrake specifically designed these rotors to this size to better align the brake pad with the outer edge of the rotor.

We have heard of several customers having compatibility issues between these rotors and Axxis Ceramic pads. We recommend Axxis Deluxe semi-metallic pads to be used with these rotors.

Rotor Material: Racing Formula Alloyed Gray Iron & Heat treated
Machining: Drilled & Slotted
Surface: EDP Coating w/cross cut grinding on friction surface

NOTE: Retaining and jack screw holes have been removed to prevent the screws from rusting and causing difficult removal of the rotors. Our two-piece rotor hats are made of aluminum which is easier for installation and removal. See detail view here.

Replacement Components

Rotor Ring: D401-02-351

Material:

0. Alloyed iron formula adds strength and heat resistance. Heat treating further improves rotor performance for a more uniform and stabilized microstructure.

Design:

0. The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler. (Illustration #1)
   
   
   
   
   
   
   
   
   
   
   
   
   
   
    
0. 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.
     
     
0. 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.
