2015-2022 Ford Mustang Shelby GT500 / GT350R / GT350 (S550) Carbon Ceramic Brake Kit — OEM-Size Replacement
S550 Shelby GT500, GT350R, and GT350 owners usually shop carbon ceramic brakes when the factory-size iron package is being punished by repeated high-speed stops, heavy rotor dust, or the cost of replacing cracked OEM carbon-ceramic parts. This StopFlex OEM-replacement kit keeps the factory brake architecture and matches the correct Shelby rotor envelope: 420 mm front / 370 mm rear for GT500, or 394 mm front / 380 mm rear for GT350 and GT350R. Carbon-ceramic rotors, matched pads, hats, and floating hardware reduce rotating unsprung mass while adding heat stability and low dust without converting the car to a non-OEM big-brake layout.
- GT500 fitment is built around the factory-size 420 mm front and 370 mm rear Shelby brake package, not a generic S550 GT Performance Pack rotor size.
- GT350 and GT350R fitment uses the Shelby-specific 394 mm front and 380 mm rear rotor references used with the factory Brembo brake layout.
- Carbon-ceramic discs cut brake dust on the open-spoke Shelby wheels and reduce rotating unsprung mass at all four corners compared with the factory iron rotor package.

For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
Carbon ceramic rotor diameter sets the smallest wheel that clears the caliper. Confirm your wheel diameter and spoke clearance with StopFlex before ordering.
Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

FAQ
Will this kit fit every S550 Mustang?
No. This page is limited to 2015-2022 Shelby GT500, GT350R, and GT350 applications with the rotor sizes listed here. It is not for EcoBoost, GT, Bullitt, Mach 1, or Performance Pack cars unless the exact Shelby brake hardware has been verified before ordering.
What should I confirm before ordering for a GT500 versus a GT350 or GT350R?
Confirm year, trim, VIN, current rotor diameters, caliper package, and wheel size. GT500 uses 420 mm front and 370 mm rear references; GT350 and GT350R use 394 mm front and 380 mm rear references, so the kit must be configured to the exact Shelby brake setup.
Does the kit retain the factory rear parking brake function?
Yes, the OEM-replacement configuration is designed around the factory rear brake layout, including the electronic parking brake interface where equipped. StopFlex still verifies the rear hardware and VIN because GT500 and GT350-family rear rotor dimensions are different.
Why move from the factory iron rotors to carbon ceramic on this Shelby?
The S550 Shelby is heavy, fast, and capable of repeated high-energy stops, which drives rotor temperature, pad transfer issues, and dust on track or aggressive street use. Carbon ceramic rotors reduce rotating unsprung mass, resist heat-related fade, and leave far less visible dust than iron while keeping the factory-size caliper geometry.
