GCX Rotors with Elemental Protection™ GEOMET® Coating Provides Long-Lasting Corrosion Resistance

GCX Elemental Protection Coated Brake Rotors by StopTech with Elemental Protection™ GEOMET® coating on rotor vanes to prevent corrosion while promoting efficient rotor cooling. GCX rotors offer class-leading application coverage as well as superior protection from corrosion and rust. GCX rotors have been engineered to restore OE performance while offering maximum durability and extended service life.

GCX rotors feature partial Elemental Protection™ GEOMET® coating on the friction surface that results in 10% faster pad bed-in while eliminating corrosion rings, as well as full Elemental Protection™ GEOMET® coating on all non-mating surfaces to inhibit rust formation. GCX rotors are double disc ground to eliminate DTV issues, and feature OE style vane designs and machined non-friction surfaces to restore OE looks and performance.

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.

Machined Surface

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 Vanes

 

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.
