Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2015-2025 Lexus RC F (SC10). Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| RC F | 380mm, 380mm (CCB) | 345mm, 345mm (CCB) | 19" |
Keep Your Factory Calipers?
Keep them if the front calipers are fixed 4-piston or more — the rear axle qualifies regardless. Front 1- or 2-piston floating calipers rule out the disc-only route; choose the Full Upgrade kit instead. Every set is machined to the factory rotor specs listed above, and aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood) only need the caliper model, pad shape, and rotor dimensions confirmed before we build.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Winter & Cold-Weather Braking
Cold facts first: an untuned ceramic disc bites less than iron on a freezing morning — physics, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now feels very close to summer. Leave extra margin on the very coldest first stops; severe-climate daily drivers should build Street Spec.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat still soaks 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.

FAQ
Does this fit any RC F, or only certain ones?
This page covers the RC F (SC10) with the exact factory rotor sizes listed: 380mm front and 345mm rear on the carbon-ceramic-equipped car. Direct replacement is valid only when the front factory calipers are 4-piston or more, which the RC F's Brembo fronts satisfy. You reuse your factory calipers and mounting points; we supply the carbon-ceramic discs, hats, pads, and floating hardware sized to those exact 380mm/345mm dimensions. If your car runs a different front rotor size, this kit is not the correct part.
How do these behave in winter and on cold first starts?
A carbon-ceramic disc that hasn't been engineered for cold operation bites less than cold iron on the first stops. That's physics, not a defect. For this RC F kit we tuned both the pad compound and the disc's ceramic coating specifically for cold starts, so cold-car braking feel now comes very close to warm summer feel. On the coldest mornings, leave a little extra following distance for the first one or two stops until the system is at temperature, then it's business as usual.
Will these clear my factory RC F wheels?
The kit keeps the factory 380mm front and 345mm rear packaging and reuses the OEM calipers, so if your current wheels clear the factory carbon-ceramic Brembo setup, they clear this kit. The RC F ships on 19-inch forged wheels, and the rotor-and-hat stack matches OEM envelope. If you run aftermarket wheels, confirm your inner barrel and spoke clearance against the original carbon-ceramic dimensions before ordering.
How much dealer cost does this actually replace?
OEM carbon-ceramic service on the RC F is expensive because the discs, pads, and wear sensors are dealer-only parts. This kit replaces all four rotors, both axle pad sets, the hats, and the floating hardware in one package while reusing your calipers. The pads are a carbon-ceramic-specific low-metallic resin-composite compound with steel, copper, and aramid fiber, running an average friction coefficient near 0.44 and holding up to about 750 °C with strong anti-fade behavior.
