These OE rotor replacement rings although are made from a better design in cooling vanes and metallurgy. However, due to the OE axle blocking the air inlets, surface mount rotors (such as these OE two piece) don’t permit cool air to enter the rotor from the outboard, side like RB’s center mount design. The the cool air admission is extremely limited. As a result, it this causes the common understanding to GT-R drivers that OE rotors are very easy to crack. 
Under such poor operating conditions, RB replacement rotor rings may still hold up, but when under extreme heat, you may still experience other ill effect that can spill over to brake pads and other components -- such as brake fading, pre-mature pad wear, brake juddering, burnt caliper boots/seal, boiling brake fluids, shorten wheel bearing life etc. 
Check your brake components often to not exceed their limits, and try our center mount design rotors to enable the system to run cooler. Just remember that heat is a brake’s #1 enemy. 

Note: This ring does not include mounting hardware. Although you can reuse the existing hardware, it is recommended that you purchase at least the economy fastener kit.

Weight Comparison

OE Ring22.0 lbs.

RB Ring21.0 lbs.

Weight Savings: 1.0 lb.


*This rotor is made to 378x34 vs OE 380x34. RB's two-piece rotors are made to the exact diameter where the pad contacts the rotor to eliminate the rusty rotor lip that forms on the outer edge of the OE rotors.


Material: Racing Formula Alloyed Gray Iron
Finish: Straight Slot
Surface Treatment: EDP Coating w/cross cut grinding on brake pad contact area
Material: Alloyed iron formula adds strength
Design: The cooling vanes are of a convergent nozzle design, which increases airflow and turbulence and keeps discs cooler. 

Other Differences: 


-Better air circulation resulting cooler operating temperature.

-Stronger brake torque with lasting performance and more resistant to wear.

-Prevent from undesirable rusting/corrosion therefore extends the life and serviceability.

-Lighter weight = quicker pedal response and higher braking efficiency.

-Help to escape the brake pad gases or other substances for more efficient braking performance.

-Save maintenance/replacement cost (rotor and pads) and down time.

  1. The rotor is directional (with RB's convergent curved vanes) vs. OE's non-directional (pillar vanes):
  2. RB iron rotors are alloyed iron vs. OE's regular iron:
  3. Disc surface (including the inner vanes) is coated with EDP vs. OE's plain surface:
  4. Weight saving: Our rotor rings save you ~2 lbs per rotor over stock.
  5. Disc surface is slotted vs. OE's plain finish:
  6. Overall performance improvement and more durable than OE:
