The Pro-System Shelby GT350R turnkey package brings Alcon caliper hardware and Pro-System brake preparation to a demanding performance application. BRK.200643 identifies the anodized configuration. The value of the package lies in treating the brakes as a complete mechanical assembly, with the friction components, caliper mounting and rotor interfaces considered together.

Alcon / Pro-System Shelby GT350R Turnkey Brake Package

A high-grip car places repeated demands on its brakes: the friction system must absorb the energy of each stop, release heat between braking zones and hold the pads consistently as temperatures change. Pro-System’s approach combines its rotor manufacturing and preparation with Alcon brake hardware and application-specific mounting components.

Features

• Shelby GT350R turnkey application
• Anodized caliper configuration
• Alcon brake hardware with Pro-System package preparation
• Vendor part number: BRK.200643
• Application-specific rotor hats and caliper mounting interfaces
• Serviceable friction components and separately identified mounting hardware

Alcon Calipers

The caliper’s job extends beyond applying clamping force. It must support the pads and maintain their relationship to the disc while hydraulic pressure, temperature and wheel loads change. Caliper mounting and the correct friction material are therefore part of the brake-system specification. This listing identifies the anodized GT350R package; replacement calipers and pad shapes should be matched to BRK.200643.

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.

Friction Material and Operating Temperature

Pad selection should reflect how the car is used, including its tires, cooling provisions and session length. A compound’s cold response, working-temperature range and wear behavior influence both road manners and track performance. Match the front and rear friction choices to the complete brake setup rather than selecting solely on a compound name.

Vehicle and Wheel Fitment

Confirm the exact GT350R vehicle, hub and wheel specification before ordering. Wheel barrel shape and spoke clearance matter as well as diameter. Parking-brake provisions and the detailed package contents must also be matched to the specific installation.

Replacement Parts

For replacement rotor rings, pads, calipers or mounting hardware, contact Alconkits with kit BRK.200643 and the axle being serviced. We will match the replacement to your exact configuration.
