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.

Slotting: there are many reasons to slot rotors. Primarily, slotting aids in removal of water and debris on the rotor surface, evacuation of hot pad "off gassing" vapor, and provides a visual wear indicator.

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.
