2018-2026+ Lexus LC500 (J100) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2018-2026+ Lexus LC500 (J100) Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2018-2026+ Lexus LC500 uses a large OEM brake package, with 400 mm front rotors and 359 mm rear rotors on the fitments covered by this page. This StopFlex OEM-size carbon-ceramic replacement kit is built for LC500 owners replacing heavy iron rotors, managing heat on fast road or track use, or reducing dark brake dust behind the factory open-spoke wheels while keeping the original caliper architecture. The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware for the listed LC500 rotor sizes only.
- OEM-size replacement for LC500 applications using 400 mm front rotors and 359 mm rear rotors; not a universal J100 brake conversion.
- Carbon-ceramic rotor construction reduces rotating and unsprung mass versus same-size iron discs, which is most noticeable on a front-heavy 5.0L V8 grand tourer during turn-in and repeated braking.
- Matched pads, hats, and floating hardware are included so the rotor assembly is supplied as a complete service package rather than bare friction rings.

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 2018-2026+ Lexus LC500?
No. This page is only for LC500 fitments that match the listed OEM-size brake package: 400 mm front rotors and 359 mm rear rotors. Confirm your VIN, trim, wheel package, and measured rotor diameters before ordering.
Does it keep the factory parking brake and driver-assist functions?
The kit is designed as an OEM-size rotor and pad replacement for the listed LC500 brake setup, so it does not require changing the factory rear parking-brake architecture. Electronic parking brake and brake-hold operation still depend on correct installation, bedding, and compatible rear fitment.
Why choose carbon ceramic instead of replacement iron rotors on an LC500?
Carbon-ceramic rotors tolerate repeated high-temperature stops with less fade, produce less visible dust than typical iron-and-pad combinations, and remove mass from a large 400 mm front / 359 mm rear brake package. That matters on the LC500 because the car combines a heavy luxury chassis with a high-output 5.0L V8.
What should I verify before buying?
Verify that your LC500 uses the 400 mm front and 359 mm rear rotor sizes, that your wheels clear the factory calipers and rotor diameter, and that you are ordering for the exact trim covered by this page. If your car has non-OEM calipers, aftermarket wheels with tight barrel clearance, or a different brake package, confirm fitment first.
