Only Centric Premium black rotors feature
Original Equipment specifications and production processes. All Centric rotors
are manufactured to meet QS and ISO Quality System Standards. Their global
suppliers have already passed these stringent quality assurance standards
because they currently supply products to the O.E. manufacturers. |
 |
Long-Lasting Protection
Centric Premium rotors utilize an Electro
coating finish that provides long lasting corrosion protection. E-coating is a
superior electro-statically applied finish designed to withstand 400 hours of
salt water exposure without rusting! Phosphate finishes utilized by other
manufacturers provide only minimal protection from the elements; these finishes
are generally only effective for the shipping and storage portion of a rotor's
life. The addition of heat and moisture eliminates the effectiveness of
phosphate finishes resulting in immediate corrosion once installed on the
vehicle.

Centric
Rotors |
 |
Inconsistencies
on the friction surface area left by interior finishing processes create
potential noise and vibration issues. These rough finish surfaces also
prolong the pad-rotor break in period, diminishing braking power which cause
longer stopping distances. |
|
Centric Premium rotors
feature a double disc ground, taper free finish. Double disc grinding
ensures parallelism, eliminates run out and provides near perfect disc
thickness variation (DTV). Double disc grinding leaves a non-directional
finish on the friction surface area for more effective pad-rotor break in.
This special finish also provides quieter and smoother stops. |
 |
Rough castings
left behind by substandard manufacturing processes create balance
inconsistencies resulting in wheel vibration related noise. The lack of
mill-to-correct balancing only exacerbates these issues. |
|
Centric Premium rotors
feature 100% fully machined finishes, including rotor hats. This extra
process provides better rotor balance and creates a cleaner, more finished
looking component. In addition, all Centric rotors are 100% inspected for
balance, and mill-corrected to a tolerance of less than 2oz. per inch. |
 |
Side-split
castings, while cheaper to produce, do not distribute heat effectively. The
result is that they transfer more heat to one side of the rotor than the
other, greatly diminishing braking power, especially in high-heat emergency
situations. |
 |
O.E. specification
center-split core casting provides proper heat transfer and thermal
efficiency, resulting in superior braking power and safety. |
|
Centric's Fabrication
Process |
 |
 |
 |
|
In the first step, the O.E. Specifications are dialed in and configured
to create the highest quality and OE precise rotors.
The rotors are precision
cut to the exact O.E. specification
guaranteeing the most accurately
fabricated rotor and flawless function.
|
|
A non-directional finish is implemented by the process of double disc
grinding.
This ensures a near perfect Disc Thickness Variation (DTV), which
guarantees
even wear and better break-in between the pad and the rotor. |
|
Last but not least, the processed rotors are
then precisely balance during
the inspection process.
Giving close attention to any inaccuracies
the rotors
are corrected to a tolerance of less
than 2 ounces/inch! |
