2008-2015 Cadillac CTS / CTS-V (2nd Gen) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
Second-gen Cadillac CTS and CTS-V owners usually shop carbon ceramic brakes after heat-checking or warping iron rotors, cleaning heavy track dust from open wheels, or chasing sharper front-end response from lower rotating mass. This StopFlex kit pairs front Brembo V6 / GT6 / GTS6 6-Piston Caliper Options with carbon-ceramic rotors up to 380 mm, then matches the rear 4-piston Brembo package, hats, pads, lines, and hardware to the confirmed trim. Because CTS and CTS-V hardware can differ by upright, hub position, and wheel clearance, StopFlex engineers the brackets and rotor-hat offsets for the exact car instead of assuming platform-wide fitment.
- GT6 front configuration uses a Genuine Brembo GT | M6 6-piston caliper with a 380 mm carbon-ceramic rotor; V6 uses the OEM Cadillac CTS-V 6-piston caliper with a 370 mm rotor, and GTS6 uses the GT | S6 caliper with a 380 mm rotor.
- The rear package is matched around Brembo V4, GT4, or GTS4 4-piston calipers, each paired with a 380 mm rear carbon-ceramic rotor for rear torque support and braking stability.
- A 380 mm rotor requires 19-inch or larger wheels on this chassis, and spoke clearance must be checked because CTS-V-style calipers sit close to the inner barrel and wheel face.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 380 mm front rotor, so the minimum wheel size is 19". Wheels under 19" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, giving the CTS / CTS-V a stiff 6-piston caliper architecture that spreads pad pressure across the rotor face for controlled clamping force and a firm pedal. The buyer chooses V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper with a 370 mm rotor, GT6 = Genuine Brembo GT | M6 6-Piston Caliper with a 380 mm rotor, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper with a 380 mm rotor. Each option is built around a genuine Brembo caliper rather than an unbranded casting, with StopFlex hats, brackets, pads, lines, and carbon-ceramic rotors matched to the ordered configuration.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options with 380 mm carbon-ceramic rotors, so rear brake torque is engineered with the front system instead of left as an undersized factory carryover. EPB or parking-brake function must be confirmed by exact year, body style, and trim before StopFlex specifies the rear hardware.
Front & rear, engineered together: A CTS-V front brake upgrade can create a nose-heavy brake balance if the rear axle is not engineered with the same rotor diameter, pad compound, and hydraulic behavior in mind. StopFlex treats the front and rear as one system, matching caliper choice, rotor-hat offset, pad compound, and line routing to the confirmed CTS or CTS-V configuration.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak 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.
Street / Track-Day / Motorsport Rotor Options
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.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this kit fit my exact 2008-2015 CTS or CTS-V trim?
Fitment is not assumed from the CTS platform name. StopFlex confirms your year, trim, body style, hub and upright package, and wheel data before specifying brackets, rotor-hat offsets, caliper mounts, and lines for your exact car.
What wheel size do I need for the 380 mm setup?
The 380 mm front or rear rotor requires 19-inch or larger wheels. Inner barrel clearance and spoke clearance still have to be checked, especially with the Brembo GT6, GT4, or GTS-style caliper profiles.
Will the parking brake or EPB still work?
Some second-gen CTS/CTS-V configurations use an electric parking brake and others use a manual parking-brake layout. StopFlex confirms your exact parking-brake system before building the rear package so the correct rear solution is specified.
Why choose carbon ceramic instead of another iron big brake kit?
Carbon-ceramic rotors cut brake dust and reduce rotating unsprung mass compared with iron rotors, while the 370 mm or 380 mm Brembo front package adds thermal capacity for hard street driving and track sessions. The main pre-order checks are exact trim, wheel clearance, intended use, and pad choice.
