2017-2023 Tesla Model 3 / Performance (pre-Highland) 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 2017-2023 pre-Highland Tesla Model 3 Performance is heavy, quick, and regen-limited once you push repeated high-speed stops on track, so owners shop CCB to reduce heat fade, brake dust, and rotating mass. This StopFlex kit pairs a Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper with 380mm front carbon-ceramic rotors and a TTSPORT EP4 4-Piston Caliper with EPB on 380mm rear carbon-ceramic rotors. The brackets, hats, offsets, lines, and mounting hardware are engineered to the confirmed Model 3 Performance trim and wheel package, not treated as a generic Model 3 bolt-on.
- 380mm front and rear carbon-ceramic rotors require 19-inch or larger wheels; spoke clearance must still be verified against the GT350 Brembo front caliper and EP4 rear caliper.
- The front axle uses the exact Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, giving this Model 3 Performance a proven fixed-caliper front upgrade for repeated high-energy stops.
- The rear axle uses a TTSPORT EP4 4-Piston Caliper with EPB so the Model 3 keeps electronic parking-brake function while adding rear thermal capacity to match the 380mm front setup.

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 the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, a fixed 6-piston OEM-derived Brembo unit selected for stable pad loading, clamping consistency, and firmer pedal response under repeated hard braking. Its Shelby GT350 provenance matters because it is a production performance-car caliper from Brembo, not an unbranded cosmetic casting. StopFlex engineers the caliper brackets, rotor-hat offset, and line routing for the confirmed 2017-2023 Model 3 Performance configuration.
Rear Caliper (Balance)
The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB to add real hydraulic rear braking capacity while retaining the Model 3’s electronic parking brake. Its 4 hydraulic service pistons support rear brake balance under deceleration, and the dedicated EPB actuator piston preserves factory parking-brake convenience.
Front & rear, engineered together: This kit is engineered as a front-and-rear system because a 380mm GT350 Brembo front conversion needs rear thermal capacity and piston balance behind it, not an unrelated rear setup. The TTSPORT EP4 shares EP4S engineering with 4 hydraulic service pistons plus 1 EPB actuator piston, two-piece heat-insulated pistons with dust boots, a forged-aluminum body, and rear-axle EPB compatibility for modern platforms.
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 2017-2023 Model 3 Performance?
StopFlex does not treat all Model 3 trims as the same fitment. For this kit, the brackets, rotor-hat offsets, caliper mounting, lines, and hardware are built after confirming your exact pre-Highland Model 3 Performance configuration.
What wheels do I need for the 380mm rotors?
The largest rotor in this kit is 380mm, so wheels under 19 inches will not clear it. A 19-inch or larger wheel is still not automatic approval because spoke shape, wheel offset, and inner barrel clearance must be checked against the GT350 Brembo front caliper and EP4 rear caliper.
Will the electronic parking brake still work?
Yes. The rear TTSPORT EP4 4-Piston Caliper with EPB is selected for platforms that require electronic parking-brake retention, using hydraulic service pistons for braking and a dedicated EPB actuator piston for parking-brake function.
Why choose carbon-ceramic rotors on a Model 3 Performance?
Carbon-ceramic rotors reduce brake dust and rotating mass compared with iron rotors, and they add thermal capacity for repeated high-speed braking where the Model 3 Performance can overwork its factory friction brakes once regen is not enough.
