Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2007-2013 BMW M3 (E90/E92/E93). Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| M3 | 360mm | 350mm | 19" |
Keep Your Factory Calipers?
Yes — if your front factory calipers are fixed 4-piston or more. The rear axle has no restriction. Cars with 1- or 2-piston floating front calipers should use the Full Upgrade kit (calipers + discs) instead. Discs are built to the factory rotor specs shown above; if you run aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood), we simply confirm the caliper model, pad shape, and rotor dimensions before production.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
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.
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.
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
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.
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
Will this fit my E90/E92/E93 M3 with the factory calipers?
Yes. This is a direct replacement for the 2007-2013 M3 (E90 sedan, E92 coupe, E93 convertible) that keeps your factory 4-piston front calipers. The kit matches the factory 360mm front and 350mm rear rotor diameters exactly, so the carbon-ceramic discs, hats, and floating hardware bolt to your existing caliper mounting without brackets or spacers. It fits only the M3 trims and rotor sizes listed on this page.
How do these behave in winter and on a cold first stop?
Physics first: an untuned cold carbon-ceramic disc bites less than cold iron until it warms. We addressed that directly. Our pad compound and the disc's ceramic coating are both optimized for cold starts, so on a January morning your first stops feel very close to summer bite instead of the vague pedal older CCB setups gave. On the coldest first pulls out of the driveway, leave a little extra following distance until temperature builds — smart practice, not a defect.
Do I need to clear a bigger wheel for these rotors?
No. Because the discs retain the factory 360mm front and 350mm rear diameters and reuse your OEM M3 calipers, any wheel that cleared your stock brakes clears these. Most E9x M3 owners run 18s or 19s, and both work as they did before. There is no caliper upsizing, so nothing changes at the wheel spoke or barrel.
How much unsprung weight do I actually save over the stock iron rotors?
Carbon-ceramic discs weigh substantially less than the factory two-piece iron rotors on the S65-powered M3, and the reduction is at each corner as rotating, unsprung mass. On a car already sensitive at the front axle, that lowers rotational inertia and helps the suspension follow the road. You get that without changing the factory 360/350mm sizing or your caliper geometry.
