19" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review 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.

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

Why Carbon Ceramic — and Why StopFlex
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.
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.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Caliper Overview
Front Caliper
The front runs a Brembo GT6 six-piston caliper, offered as three options: V6 (OEM Cadillac CTS-V), GT6 (GT | M6), and GTS6 (GT | S6). All six pistons work a single monobloc body over a 380 or 355 mm rotor, so pedal pressure stays consistent instead of drifting as the pads and fluid heat up under repeated EV regen-plus-friction stops.
Rear Caliper
The rear pairs to a Brembo four-piston caliper in V4, GT4, or GTS4 form on a 355 mm rotor, adding real thermal capacity at the back so the front pads aren't doing all the work. It's matched to your confirmed trim and retains the factory electronic parking brake function.
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
Before ordering, tell us the exact vehicle, current rotor sizes, and caliper type. Nothing goes to production until the build is confirmed against your VIN-level configuration.
FAQ
How does this kit brake in cold winter weather?
Cold carbon-ceramic physics is real: an untuned ceramic disc bites less than cold iron on the first stops, which is normal, not a fault. We tuned both the pad compound and the disc's ceramic coating for cold starts, so first-stop feel on a cold car now sits very close to summer feel. On the coldest mornings, leave a little extra following distance for the first one or two stops until everything is up to temperature.
Will this fit my exact MINI Cooper EV trim?
Every kit is engineered for your confirmed J01/J05 trim, not the platform in general. Brackets, rotor-hat offsets, and caliper mounting are cut to your car's specific knuckles, hub geometry, and wheel ET. Trims that share the Cooper EV name can differ mechanically, so we build to the trim you confirm rather than assuming a one-size bolt-on.
What wheels do I need to run the 380 mm front rotor?
The 380 mm front rotor requires a minimum 19-inch wheel; anything under 19 inches will not clear the caliper. Spoke shape and inner-barrel clearance also matter, so send us your exact wheel spec when we confirm fitment. If you plan to stay on smaller wheels, the 355 mm front option may be the better route.
Does the kit keep my electronic parking brake?
Yes. The Cooper EV uses a factory electronic parking brake, and the Brembo V4, GT4, or GTS4 rear caliper on the 355 mm rotor is specified to retain that EPB function for your trim. You keep normal park-brake operation with no dashboard faults.
