PRODUCT INFORMATION
The C8 Z06 combines high corner-entry speeds with the grip to place substantial demands on its brakes. 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.
Alcon / Pro-System C8 Z06 18-inch-Wheel Brake Systems
Select 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. It should be treated as a separate system choice when ordering and servicing the brakes.

Alcon Caliper Configurations
The CR6420 and CAR8949Y55 configurations provide two defined Alcon caliper specifications. 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.
Floating Two-Piece Rotors
Pro-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.
Ventilation and Friction Surface
Braking 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.
Pro-System Rotor Preparation
Pro-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.
Hats, Brackets and Serviceability
The 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.
18-inch Wheel Clearance
An 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.
Replacement Parts
For replacement rotor rings, pads, calipers or mounting hardware, contact Alconkits with kit BRK.200606 / BRK.200605 / BRK.200627 and the axle being serviced. We will match the replacement to your exact configuration.

Alcon Big Brake Kit common questions
Alconkits - the primary Alcon distributor
Why should you buy direct from AlconKits.com?
General retailers and marketplaces list Alcon brake kits, but they typically cannot advise on fitment, wheel clearance, pad compounds, or long-term service parts. You can buy Alcon Brakes from lots of places - but you SHOULD buy them from Alconkits.com. Alconkits.com is a specialist distributor focused exclusively on Alcon systems.
What support do I get when buying from Alconkits.com?
You get brake experts live every time. We answer the phone with 25 years of Alcon Brakes support. Our experts will help you choose the right kit, with the right fit, guaranteed. Plus, when you need replacement parts and service knowledge, you will only get that from Alconkits.com - not someone who just sells general automotive parts.
What happens if I need pads, rotors, or service parts later?
This is an excellent question to ask. We stock replacement parts for everything we sell - and maintain a full cross-reference catalog for all compatible parts. When you buy from Alconkits.com an authorized primary distributor of Alcon Brakes you will get a lifetime of advice and support that other vendors cannot match.
Is Alconkits.com an authorized Alcon distributor?
Yes. You can find authorized dealers on the manufacturers website - and we are seen as one of the largest most knowledgeable dealers in the world, and certainly in the United States.
What are the main reasons people choose Alconkits?
Factory-engineered systems designed for brake performance and durability require expert advice
Lifetime technical support included when purchased from Alconkits.com.
Support beyond just sale, we help you select pads, ensure fitment, and service your brakes.
In short, you want an expert driven purchase decision, from a vendor that provides value beyond the product, with service, support, and expertise. That is the Alconkits.com promise delivered every day.
Installation
What tools do I need to install?
Our brake kits require common hand tools for installation. You will need a torque wrench, brake fluid (2 pints), and loctite.
What if I run into issues while installing?
We pride ourself in expert advice. You can call or text us at 630-360-2548 for expert technical and installation advice.
Are any other modifications required?
For OEM installations where wider rotors are fitted, you should expect to remove or trim the rotor dust/heat shield. This often interferes with larger rotors but is no longer needed due to our upgraded components.
Will I need a new Master Cylinder
No. All of our brake kits are designed specifically to work with the hydraulic ratio of your stock master cylinder
Do I need wheel spacers
We provide a fitment template for you to check clearance in advance. In some cases a small spacer may be required and we provide those when we are sure they are needed.
Are brake pads included?
Yes. We include the appropriate brake pads for all our brake kits. In some cases we offer multiple compounds for you to customize your experience. We stock a wide variety of pads for Alcon Brake kits here.
Break In questions
Do I need to brake in new rotors/pads?
Yes! We highly recommend following our brake pad/rotor bed in process. This ensures that an even layer of pad material is deposited on the rotor to eliminate shudder, increase rotor life, and to heat temper the new rotors for longer life.
What about noise and dust?
Noise and dust are related to the brake pad compound. Higher temp pads have more metallic composition and will therefore increase potential noise and dust the more aggressive the pad. For squealing issues we recommended loosening the caliper and re tightening it. This will sometimes change the caliper "frequency". Additionally "sticky shims" or our titanium pad shims will reduce noise.
Operational Questions
Is this compatible with my ABS?
Yes! We test our brakes to ensure they are fully compatible with your stock ABS on all models we release.
How long do they last?
Lifetime of components is massively variable based on how they are used. High dust/dirt/salt environments will wear seals out more quickly. Heavy Duty or Track use will also affect rotor and pad life.
What is the warranty?
We support the manufacturers 12 month/12000 mile warranty against factory defects and material issues. You can find more details here.
