2025-2026+ Zeekr 007 GT CCB Big Brake Kit — Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
The Zeekr 007 GT is a heavy, high-output electric shooting brake, and repeated high-speed braking can expose the limits of the factory iron system through heat, dust, and rotor mass. This StopFlex Kit Upgrade pairs 390mm front carbon-ceramic rotors with the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, then matches the rear with 380mm carbon-ceramic rotors and a TTSPORT EP4 4-Piston Caliper with EPB. The result is more front-axle heat capacity, lower rotating and unsprung mass than comparable iron hardware, reduced brake dust on open 20 inch wheels, and trim-specific fitment instead of a platform-wide assumption.
- 390mm front and 380mm rear carbon-ceramic rotors are sized for the Zeekr 007 GT’s EV mass and available AWD output, with 20 inch minimum wheel clearance required at the front.
- The front axle uses the exact Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, not a generic six-piston casting or cosmetic caliper cover.
- Rear braking is built around the TTSPORT EP4 4-Piston Caliper with EPB, so the 007 GT keeps electronic parking-brake functionality while adding rear carbon-ceramic thermal capacity.

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 390 mm front rotor, so the minimum wheel size is 20". Wheels under 20" 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 upgrade uses the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, a credible OEM-derived Brembo performance caliper built for a high-load front axle rather than a universal aftermarket body. Its six-piston layout spreads clamping force across the pad face to support stable pedal response and even pad loading on the 390mm carbon-ceramic rotor. StopFlex machines the brackets and rotor-hat offsets around the confirmed Zeekr 007 GT trim and wheel package, not around an assumed shared platform dimension.
Rear Caliper (Balance)
The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB on a 380mm carbon-ceramic rotor to add rear thermal capacity and keep the braking system from becoming front-heavy. The EP4 uses four hydraulic service pistons plus a dedicated EPB actuator piston, preserving the Zeekr 007 GT’s electronic parking-brake convenience.
Front & rear, engineered together: This kit is engineered as a front-and-rear system so piston area, rotor diameter, hat offset, and caliper position are matched together instead of pairing a large front conversion with an under-supported rear axle. The TTSPORT EP4 rear caliper shares EP4S-style engineering, including four hydraulic pistons, a dedicated EPB actuator piston, forged-aluminum construction, dust boots, and heat-insulated piston design, which helps maintain rear-axle stability under repeated braking.
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 every 2025-2026+ Zeekr 007 GT trim?
No universal platform fitment is assumed. StopFlex builds the brackets, rotor-hat offsets, and caliper mounting around your confirmed 007 GT trim, RWD or AWD layout, factory brake package, hub geometry, and wheel specifications before production.
What wheel size do I need for the 390mm front rotor?
The 390mm front rotor requires at least a 20 inch wheel. Diameter alone is not enough; StopFlex also checks spoke shape, inner barrel clearance, wheel offset, and caliper-to-spoke clearance for the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper.
Will the electronic parking brake still work?
Yes. The rear package uses the TTSPORT EP4 4-Piston Caliper with EPB, which has four hydraulic service pistons for braking and a dedicated EPB actuator piston for the parking-brake function.
Why switch a Zeekr 007 GT from iron brakes to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, resist heat-related fade during repeated hard stops, and remove rotating mass compared with a similarly sized iron rotor. On the 007 GT, the 390mm front and 380mm rear sizing targets the heat load of a heavy, high-torque EV without relying on factory-sized friction hardware.
