StopTech Centric Premium Front Brake Rotor Subaru 2009-2014 WRX / 2013-2020 BRZ | 120.47021

Centric Premium black rotors feature Original Equipment specifications and production processes. These Centric rotors are manufactured to meet QS and ISO Quality System Standards. 

Centric premium rotors utilize an Electrocoating 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 in the vehicle.

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. 

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, Centric Premium rotors are inspected for balance and mill-corrected to a tolerance of less than 2oz. per inch.
