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.
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.

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