*Double Disc Ground Braking Surface*
Nearly all 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.

*Fully Machined Hats Centric*
Premium rotors feature 100 percent fully machined finishes including rotor hats. This extra process provides better rotor balance and creates a cleaner, more finished looking component.

*Symmetric Vane Casting*
The profile of the rotor's cooling vane affects its ability to dissipate heat. Ideally the vane should have the same thickness at the points where it connects to the inner and outer friction plates. This is accomplished with symmetric vane core castings that provide proper heat transfer and thermal efficiency. This thickness symmetry in the vane promotes the uniform transfer of heat from both friction plates into the cooling vanes. Competitors' vanes are often asymmetrical, which can lead to uneven heat transfer and compromises in performance and cooling.
