Pro-System’s 18-inch-wheel packages bring Alcon calipers and dedicated disc configurations to that build, with a choice between the CR6420 system, the nickel-plated CAR8949Y55 system and a next-generation GT3 package. These are three distinct complete-car configurations, each with its own vendor part number.\u003c\/p\u003e\u003ch2\u003eAlcon \/ Pro-System C8 Z06 18-inch-Wheel Brake Systems\u003c\/h2\u003e\u003cp\u003eSelect the system around the intended wheel and brake configuration. The next-generation GT3 option changes the caliper specification and is listed with its own front and rear disc diameters.

ENP denotes electroless nickel plating on the CAR8949Y55 option. The next-generation GT3 package is a separate caliper architecture, with a D64 front pad reference. Keep these distinctions with the kit part number when selecting pads, seal components or replacement calipers. Caliper finish and visual similarity are not sufficient to identify an interchangeable service part.\u003c\/p\u003e\u003ch3\u003eFloating Two-Piece Rotors\u003c\/h3\u003e\u003cp\u003ePro-System’s two-piece floating rotor design separates the iron friction ring from the aluminum mounting hat. Under repeated hard braking, the ring heats and expands much faster than the hub area. The floating attachment accommodates that growth instead of forcing the friction ring and hat to behave as a single rigid casting. It also provides a serviceable assembly: a worn ring can be replaced while a sound hat is retained.\u003c\/p\u003e\u003ch3\u003eVentilation and Friction Surface\u003c\/h3\u003e\u003cp\u003eBraking converts the car’s kinetic energy into heat. The rotor must absorb that energy during the stop and release it between braking zones. Pro-System’s ventilated, slotted iron rotors combine internal cooling passages with a machined friction face. The vanes move air through the disc, while the slots help keep the pad contact surface clear. Rotor diameter, thickness, pad selection and cooling airflow all contribute to the system’s operating temperature.\u003c\/p\u003e\u003ch3\u003ePro-System Rotor Preparation\u003c\/h3\u003e\u003cp\u003ePro-System machines its iron rotors in Mooresville, North Carolina, using a specially formulated grey cast iron chosen for thermal stability and friction performance. Dyno bedding prepares the rotor friction surfaces under controlled conditions before installation. This preparation is part of the Pro-System approach to building a brake package, alongside precision-machined hats, dedicated brackets and floating rotor hardware. Pad inclusion and compound remain specific to the ordered kit.\u003c\/p\u003e\u003ch3\u003eHats, Brackets and Serviceability\u003c\/h3\u003e\u003cp\u003eThe rotor hat connects the friction ring to the hub; the caliper bracket locates the caliper relative to that ring. Their dimensions are application-specific, even when two kits use the same caliper family or rotor diameter. Keeping the correct combination matters for alignment, pad contact and clearance. Order replacement rings, hats, brackets and mounting hardware against the complete kit part number. Rotor bobbin components are supplied as complete hardware kits.\u003c\/p\u003e\u003ch3\u003e18-inch Wheel Clearance\u003c\/h3\u003e\u003cp\u003eAn 18-inch wheel designation is only the starting point for fitment. The inner barrel, spoke profile, offset and balance-weight positions must clear the selected caliper and disc assembly. Check against the template for the exact kit and wheel before ordering; the standard C8 kit template should not be substituted for a Z06 package.\u003c\/p\u003e\u003ch3\u003eReplacement Parts\u003c\/h3\u003e\u003cp\u003eFor replacement rotor rings, pads, calipers or mounting hardware, \u003ca href=\"mailto:sales@alconkits.com?subject=Replacement%20parts%20for%20BRK.200606%20\/%20BRK.200605%20\/%20BRK.200627\"\u003econtact Alconkits\u003c\/a\u003e with kit BRK.200606 \/ BRK.200605 \/ BRK.200627 and the axle being serviced.
