2024-2026+ Tesla Model 3 / Performance (Highland Refresh) 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 2024-2026+ Tesla Model 3 Highland buyer is usually trying to add heat capacity for repeated high-speed stops, cut iron-rotor dust on open wheels, and reduce rotating mass without losing daily drivability. This StopFlex kit pairs 380 mm carbon-ceramic rotors with a Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper up front and an EPB-compatible TTSPORT EP4 4-piston rear caliper so the brake package is sized as a complete front/rear system. Each kit is built for the confirmed Highland trim, wheel package, and offset data, because Model 3 and Model 3 Performance fitment cannot be assumed from the chassis name alone.
- 380 mm front and rear carbon-ceramic rotors require 19 inch or larger wheels; wheels below 19 inch will not clear the rotor, and spoke clearance must still be checked against the caliper profile.
- The front axle uses a Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, giving the Highland platform a fixed multi-piston front caliper with larger thermal hardware than the factory daily-use brake package.
- The rear axle keeps electronic parking-brake function through the TTSPORT EP4 4-Piston Caliper with EPB, matching rear thermal capacity to the 380 mm front upgrade instead of leaving the rear as an afterthought.

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 caliper is the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, a fixed 6-piston OEM-derived Brembo unit selected for stable pad loading and consistent pedal response under repeated hard stops. Its provenance matters: this is a genuine production performance caliper from a high-output track-capable Mustang application, not an anonymous universal casting. StopFlex engineers the bracket position, rotor centerline, and hose layout around this exact caliper and the customer’s confirmed Model 3 Highland trim.
Rear Caliper (Balance)
The rear caliper is the TTSPORT EP4 4-Piston Caliper with EPB, which adds real rear-axle braking capacity while preserving the Model 3’s electronic parking-brake function. Its 4 hydraulic service pistons support brake-bias stability under deceleration, while the dedicated EPB actuator piston keeps OE-style parking-brake convenience.
Front & rear, engineered together: This kit is engineered as a front and rear system so the 380 mm carbon-ceramic rotors, Shelby GT350 Brembo front calipers, and EP4 rear EPB calipers work from a matched hydraulic and thermal package. That matters on the Model 3 Highland because adding only front brake capacity can leave the rear axle underutilized during repeated high-energy stops.
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 2024-2026+ Model 3 Highland or Performance Highland?
Fitment is confirmed per vehicle, not assumed from the Model 3 platform. StopFlex matches the brackets, rotor-hat offsets, caliper mounting, and brake-line routing to your exact Highland trim, because standard and Performance variants can differ in brake hardware, upright geometry, and wheel clearance.
What wheel size do I need for the 380 mm carbon-ceramic rotors?
The 380 mm front and rear rotors require 19 inch or larger wheels. Wheels under 19 inch will not clear the rotor, and 19 inch or larger wheels still need spoke-clearance verification for the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper and rear EP4 caliper.
Will the electronic parking brake still work?
Yes. The rear TTSPORT EP4 4-Piston Caliper with EPB uses 4 hydraulic service pistons for braking plus a dedicated EPB actuator piston, so the Model 3 retains electronic parking-brake operation while gaining a rear big-brake package.
Why use carbon-ceramic rotors on a Model 3 Highland?
Carbon-ceramic rotors reduce brake dust compared with iron rotors, cut rotating and unsprung mass, and add heat capacity for repeated high-speed braking. On a quick, heavy EV such as the Model 3 Highland Performance, that combination targets the real problems owners notice during fast road use and track sessions: heat, dust, and rotor wear.
