What makes the best brake rotors?
Details, details, details, and value!
UUC Ultimate OE-size replacement rotors are slotted, plated,
and manufactured using the best techniques and materials.
Plating:
Multi-stage plating resists unsightly corrosion on the rotor hub and
unswept areas of the rotor face.
Precision: due to the ultra-precise tolerances
used for run-out, parallelism, and surface flatness, absolutely no
pre-installation machining is required for smooth operation without
vibration or shimmy.
Manufacturing details:
- Meets SAE J431 standard
for grade 3000 gray cast iron
- Alloying: Copper and
Chromium added to achieve specific hardness and tensile strength.
- Precision-controlled
cooling during the casting process creates a uniform distribution of
graphite flakes, thus increasing wear resistance and the ability to
dissipate heat. In contrast, premature cooling of cast iron can cause
iron brittleness, thus making the brake rotor more likely to warp or
crack, especially when overheated under hard braking conditions.
- Run-out less than .004".
- Parallelism of machined
surfaces within .0005" tolerance.
