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) donít permit cool air to enter the rotor from the outboard, side like RBís 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.
RB Rotor has air flow RB Rotor has air flow
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 rotors to enable the system to run cooler. Just remember that heat is a brakeís #1 enemy.

Weight Comparison

OE Ring 23.0 lbs.
RB Ring
(1.2 mm thicker)
22.5 lbs.

Weight Savings: 0.5 lb.

Kit contains:

  • 2 ea. RB Replacement rotor rings
  • 20 ea. M6 bolts
  • 20 ea. M6 lock nuts

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:

  1. The rotor is directional (with RB's convergent curved vanes) vs. OE's non-directional (pillar vanes):
  2. -Better air circulation resulting cooler operating temperature.
  3. RB iron rotors are alloyed iron vs. OE's regular iron:
  4. -Stronger brake torque with lasting performance and more resistant to wear.
  5. Disc surface (including the inner vanes) is coated with EDP vs. OE's plain surface:
  6. -Prevent from undesirable rusting/corrosion therefore extends the life and serviceability.
  7. Weight saving: Our rotor rings save you ~2 lbs per rotor over stock.
  8. -Lighter weight = quicker pedal response and higher braking efficiency.
  9. Disc surface is slotted vs. OE's plain finish:
  10. -Help to escape the brake pad gases or other substances for more efficient braking performance.
  11. Overall performance improvement and more durable than OE:
  12. -Save maintenance/replacement cost (rotor and pads) and down time.

5 of 5 2012 GTR OEM Replacement Rotor Review July 19, 2012
Reviewer: Sakred from Santa Ana, CA  
I recently had the displeasure of cracking the front OEM Nissan rotors on my 2012 BE GTR. As many of you know the OEM rotors crack when used on track. It took me 1 track event at Buttonwillow raceway, and less then 6k miles to crack my rotors to the point where they needed to be replaced. I researched some options and came across the Alcon rotors which were about 1k a piece. Not willing to pay 2k for a set of rotor rings I decided to wait till other companies offered a more competitive after market solution. I recently purchased a set of RacingBrake OE replacement rotors that are slotted rather than drilled like the OEM Nissan rotors. This setup is a great for people who like to track their GTRs. My rotors are still intact after all of the heat cycles they went through. The value these OE replacement rotors provide is second to none. I am already doing 100% better then what I did with the OEM Nissan rotors.
