Rotor Material: Racing Formula Alloyed Gray Iron & Heat treated
Machining: OpenSlot
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. These two-piece rotor hats are made of aluminum which is easier for installation and removal.

Save 5.5 lbs from EACH rotor!

RacingBrake rotors are engineered and manufactured to meet the needs of the performance enthusiasts. From 3D CAD design to tooling development, casting, machining, and surface coating, we control all production processes to insure quality, performance, and value. 

Our patented designs, combined with proprietary alloyed cast iron and precision machining assure you that our brake products will achieve the highest level of performance.

Material:

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

Design:

1. The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and makes discs cooler. (Illustration #1)
   
   
   
   
   
   
   
   
   
   
   
   
   
   
    
2. 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. 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.

    

	Convergent Vane - US Patent#: 7097007 Staggered cooling vanes distribute heat more evenly and efficiently across disc surface while increasing airflow through rotor. Less fade Longer disc and pad life
Open Slots - US Patent#: 7097007 Combines the benefits of drilling and slotting without large reduction in disc surface area. Provides exit path for brake dust and other debris Self cleaning slots - never clog up like traditional slotting
	Reinforced Ribs - US Patent#: 7219777 Extended ribs increase the air flow and rotor strength from warping. Resists rotor distortion Stronger and cooler rotors
Center Mount - US Patent#: 7568560 Center-mount rotors provide air inlets from BOTH inboard and outboard. (as opposed to traditional surface mount design only from inboard) Balances stress and heat load Reduces heat transfer to hat resulting in cooler discs

Open Slot Advantages:

• Has the advantages of both drilled & slotted rotors
• Allows the disc to expand and contract and prevents the disc from cracking or warping
• Increasing cooling area and retains more friction surface
• Slots relieves thermal stress
• Slots are self cleaning and the pad build up will not clog the slots and are exhausted via the rotor edge keeping the disc surface clean
• Reduces brake pad dust buildup and keeps the wheel clean through vacuum effect

NOTICE

Brake pad deposit is a substance emitted from the brake pads under high temperature and transferred onto the rotor surface. Pad deposit can cause vibration, pedal pulsation and hot spots on rotors surface, resulting in thermal cracks or premature brake failure.Pad deposit does not come from the rotor, but it can cause the rotor to fail. 

Why does brake pad deposit occur? 
Brake pad deposit occurs when a brake pad and a rotor are not compatible with each other. RacingBrake two-piece rotors are made from specially formulated alloys and high carbon cast iron. Our disc material is formulated to a Brinnell hardness level of 207-255, harder than the material used by other rotor manufacturers. As a result, our rotors have been proven on the racetrack to be more highly resistant to wear, warping or thermal cracking under extreme heat cycles.

Since the disc material is has a higher hardness level than OE or other manufacturers' rotors, the same racing pads (brands such as Carbotech or Ferodo) that may have worked great on your original rotors may not work well on RB rotors. These pads, commonly used by weekend racers, are affordable but are often not aggressive enough to be used with RB rotors. Using these types of pads on RB rotors may result in pad deposit at high temperatures, and/or an unsatisfactory "bite" on the rotor at low temperatures. 

The opposite issue occurs if a pad is too aggressive for its rotor, for instance, using track pads on an OE rotor. The abrasiveness of the pad will wear down the rotor very quickly. This is why it is critical to make sure that the pads and rotors that you use are compatible with each other. 

For optimal performance and safety, be sure to use true racing pads in conjuntion with RB rotors: brands like Mintex, Raybestos, (Porterfield), Cobalt or Pagid. Racing Brake have worked closely with Hawk to develop rotors that are compatible with these pads. True racing pads are able to handle high temperatures without the concern of pad deposit. Any use of noncompatible pads is at your own risk.
