Centric Premium Rotors are blank, 1-piece, direct replacement discs for your factory brake system. These “black” rotors feature a special anti-corrosion e-coating that gives them their distinctive look. StopTech Premium Rotors are particularly desirable in fleet or emergency. Vehicle applications. when an upgrade to Power Slot or SportStop performance. Replacement rotors is not possible. Like many StopTech, Power Slot, and SportStop rotors. Centric Premium Rotors offer several key advantages over stock rotors. E-coating, Double Disc Ground, Machined Finishes, Split Castings, and Mill Balancing is just some of the processes we use. *E-Coat Finish* 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 saltwater exposure without rusting. Finishes used by other manufacturers provide only minimal protection from the elements and are generally only effective for the shipping and storage portion of a rotor’s life. sto120-66065 sto120-66065
The addition of heat and moisture eliminates the effectiveness of many of those finishes resulting in immediate corrosion once installed in the vehicle. *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 a more effective pad-rotor break-in.
