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.
Optional 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.
 |
Details: These slots do not
extend all the way to the edge of the rotor for a very specific
reason; this maintains the structural integrity of the rotor.
Other brands with slots all the way to the end have created
"stress risers" where cracking may develop. No such
problem exists with this design. Additionally, directional
slotting enhances effectiveness. |
 |
NO DRILLING! Drilled holes in rotors
often used for "show" are prone to cracking and catastrophic
failure. The holes create stress risers which will lead to this
sort of failure. Additionally, drilled holes do not improve
cooling, rotary-vane rotors lose efficiency when
drilled because cooling air does not not pass through the rotor
circumferentially but is instead prematurely evacuated by the holes.. |
Plating: Multi-stage black plating resists
unsightly corrosion on the rotor hub and unswept areas of the rotor face.
Rotor after normal use, normal silver color in swept area.
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 standards for brake rotor 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.
This attention to detail makes
these rotors suitable for street, auto-x, track, and race use.
