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.
| 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
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.
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.
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 Brembo's V6 / GT6 / GTS6 6-piston caliper family, and you pick the option that fits your build: V6 is the OEM Cadillac CTS-V 6-piston on a 370 mm rotor, GT6 is the Brembo GT | M6 on 380 mm, and GTS6 is the Brembo GT | S6 on 380 mm. All three give you stable, repeatable clamping and a firm pedal on this 4,000-plus-pound sedan.
Rear Caliper
The rear pairs with Brembo's V4 / GT4 / GTS4 4-piston caliper on a 380 mm rotor — V4 is the OEM CTS-V 4-piston, GT4 the Brembo GT | M4, GTS4 the Brembo GT | S4. This adds real rear thermal capacity for repeated hard stops and retains the factory 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
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
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 kit clear the parking brake on my CTS?
Yes. The 3rd-gen CTS uses an electronic parking brake built into the rear, and the V4/GT4/GTS4 rear caliper and 380 mm rotor setup is engineered to keep that EPB working normally. You won't lose parking-brake function or throw dash faults after the swap.
Is this a bolt-on kit that fits any 2014-2019 CTS?
No, and we won't pretend it is. Trims within the CTS family differ mechanically — the CTS-V's knuckles, hub geometry, and wheel clearance are not the same as a standard CTS. We build the brackets, rotor-hat offsets, and caliper mounting to your exact confirmed trim, so this is bespoke per car, not a platform-wide bolt-on.
How do these brakes behave in cold weather and winter?
A cold, untuned carbon-ceramic disc bites less than cold iron — that's normal physics, not a defect. We've optimized both the low-metallic pad compound and the disc's ceramic coating for cold starts, so first-stop feel on a cold morning now comes very close to summer feel. Leave a little extra following distance on the coldest first stops and you're set.
What wheels do I need to clear these rotors?
The front runs up to a 380 mm rotor (370 mm on the V6 option) and the rear is 380 mm, so you need a minimum 19-inch wheel. Anything under 19 inches will not clear the caliper, and spoke design matters too — confirm your wheel fits over the caliper before ordering.
