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 |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 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 runs a Brembo V6 / GT6 / GTS6 6-piston caliper on a 380 mm rotor — you pick the option: V6 (OEM Cadillac CTS-V), GT6 (Brembo GT | M6), or GTS6 (Brembo GT | S6). Six opposed pistons keep pad pressure even across a big disc, so pedal feel stays firm on a heavy C216 coupe even after repeated hard stops.
Rear Caliper
The rear uses a Brembo V4 / GT4 / GTS4 4-piston caliper on a matching 380 mm rotor, chosen from V4 (OEM Cadillac CTS-V), GT4 (Brembo GT | M4), or GTS4 (Brembo GT | S4). It adds rear thermal capacity to balance the front and handles the C216's factory parking-brake function within the corner assembly.
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
High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.
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
Will this fit my exact CL trim, or is it a one-size platform kit?
It is built to your confirmed trim, not assumed from the C216 name. A CL63 or CL65 AMG can carry different front knuckles, hub geometry, and wheel offset than a CL550 or CL600, so we match the brackets, rotor-hat offsets, and caliper mounting to your specific car. We confirm your trim and wheel clearance before anything ships.
What wheels do I need to clear the 380 mm rotors?
The front and rear both use 380 mm discs with Brembo 6-piston front and 4-piston rear calipers, so you need at least a 19-inch wheel. Anything under 19 inches will not clear the caliper, and spoke shape still matters — send us your wheel model and we will verify caliper-to-spoke clearance before you order.
How do these brake in the cold during winter?
A cold, untuned carbon-ceramic disc bites less than cold iron — that is physics, not a fault. We tune both the pad compound and the disc's ceramic coating specifically for cold starts, so first-stop feel on a winter morning now comes very close to summer feel. Leave a little extra following distance on the first few stops of a truly cold day and you will be fine.
What comes with the kit and how do the calipers work?
You get calipers, carbon-ceramic rotors, pads, hats, hardware, and stainless lines for both axles. Front is your choice of Brembo V6, GT6, or GTS6 6-piston caliper; rear is V4, GT4, or GTS4 4-piston. The pads are a carbon-ceramic-specific low-metallic resin compound with steel, copper, and aramid fiber, about 0.44 average friction and heat resistance near 750 °C for strong fade resistance on a heavy coupe.
