19" |
Every StopFlex kit is bespoke-engineered for your exact model and trim — brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, never assumed from the platform. Trims that share a chassis name can differ mechanically: a pure performance variant often carries different knuckles, hub geometry, and wheel ET clearance than the standard models, so parts that bolt onto one are not the parts that fit the other. Calipers, pads, rotor hats, floating hardware, and brake lines ship as one matched system built to your confirmed trim. Modified knuckles, uprights, or non-factory suspension mounting points must be reviewed before ordering.
The 380 mm rotor sets the minimum wheel size at 19" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |

| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |

Why Carbon Ceramic — and Why StopFlex
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.
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.
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.
Caliper Overview
Front Caliper
The front uses your choice of the Brembo V6 / GT6 / GTS6 six-piston caliper on a 380 mm carbon-ceramic rotor. V6 is the OEM Cadillac CTS-V casting, GT6 is the Brembo GT | M6, and GTS6 is the GT | S6 — all six pistons for even pad loading and a firm, repeatable pedal on a heavy 001.
Rear Caliper
The rear pairs a Brembo V4 / GT4 / GTS4 four-piston caliper with a matched 380 mm carbon-ceramic rotor, adding real rear thermal capacity on a 2-ton-plus EV. We spec the rear bracket and bracket to retain the factory electronic parking brake function on your 001.
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.
Get Your Fitment Confirmed
Send the exact vehicle details, current rotor sizes, and caliper type before ordering. Every StopFlex order is confirmed against your VIN-level configuration before production.
FAQ
Does this fit my exact Zeekr 001 trim, or is it a generic 001 kit?
It is built to your confirmed trim, not the platform. The 001 and the FR do not share front knuckles, hub geometry, or wheel clearance, so brackets, rotor-hat offsets, and caliper mounting are cut for the specific car you tell us. We make no platform-wide bolt-on claim — you confirm your VIN and trim, and the kit is machined to match.
How does this brake in cold Zeekr winters?
An untuned cold carbon-ceramic disc bites less than cold iron on the first stops — that is physics, not a fault. We tuned both the low-metallic resin pad and the disc's ceramic coating for cold starts, so cold-car feel on the 001 now comes very close to warm feel. Still leave a little extra following distance on the first stops of a freezing morning.
What wheels do I need to clear the 380 mm rotors?
The largest rotor here is 380 mm front and rear, so 19-inch wheels are the minimum — anything smaller will not clear the caliper. Spoke shape matters too, not just diameter, so send us your wheel details and we confirm clearance against the chosen Brembo six-piston front caliper before you buy.
Will the rear kit keep my electronic parking brake working?
Yes. The 001 uses a factory electronic parking brake, and the rear V4 / GT4 / GTS4 four-piston caliper and bracket are specified to retain that EPB function. You keep normal auto-hold and park operation with no dash faults.
