2017-2023 Tesla Model 3 / Performance (pre-Highland) CCB Big Brake Kit — TTSPORT 8657 6-Piston Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
The pre-Highland Model 3 Performance is heavy, quick, and commonly pushed harder than its factory iron brakes can tolerate on repeated high-speed stops or track sessions. This StopFlex kit pairs a TTSPORT 8657 6-Piston Caliper with 380mm front carbon-ceramic rotors and a TTSPORT EP4 4-Piston Caliper with EPB on 380mm rear rotors to add heat capacity, reduce brake dust, and cut rotating mass versus iron. Fitment is engineered around the buyer’s exact Model 3 Performance trim and wheel clearance, not assumed from the shared Model 3 chassis.
- 380mm front and rear carbon-ceramic rotors require 19-inch or larger wheels; spoke clearance must still be confirmed before production.
- The TTSPORT EP4 rear caliper preserves the Model 3’s electronic parking brake while adding 4 hydraulic service pistons at the rear axle.
- This kit is built for the 2017-2023 pre-Highland Model 3 Performance use case: repeated heavy braking, low-dust open-wheel appearance, and trim-specific fitment validation.

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.
| Wheel Size (Standard) | Disc Range |

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The TTSPORT 8657 6-Piston Caliper is the primary front-axle upgrade in this kit, spreading clamping load across a larger pad area than a sliding or smaller fixed caliper can support. TTSPORT is a performance brake manufacturer, and this caliper is selected here as a purpose-built big-brake component matched to a 380mm carbon-ceramic rotor. Its fixed multi-piston architecture supports firmer pedal response and more even pad loading under repeated high-energy stops.
Rear Caliper (Balance)
The TTSPORT EP4 4-Piston Caliper with EPB adds real rear-axle braking capacity instead of leaving the rear system as a visual afterthought. It uses 4 hydraulic service pistons plus a dedicated EPB actuator piston, so the Model 3 keeps electronic parking-brake function while gaining a matched 380mm rear carbon-ceramic rotor.
Front & rear, engineered together: Front and rear are engineered together so piston area, rotor diameter, hat offset, bracket geometry, and line routing are matched to the confirmed Model 3 Performance configuration. That matters on this chassis because a front-only big-brake change can alter pedal feel and thermal balance without adding rear-axle capacity or preserving the EPB cleanly.
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 fit my exact 2017-2023 Model 3 Performance?
StopFlex builds this kit after confirming your exact pre-Highland Model 3 Performance configuration. Brackets, rotor-hat offsets, caliper mounting, brake lines, and hardware are matched to your trim and wheel setup, not treated as a universal Model 3 platform fit.
What wheels do I need for the 380mm setup?
The 380mm front and rear rotors require 19-inch or larger wheels. Barrel diameter is only the first check; StopFlex also confirms spoke clearance for the TTSPORT 8657 front caliper and TTSPORT EP4 rear caliper before production.
Will the factory electronic parking brake still work?
Yes. The rear TTSPORT EP4 4-Piston Caliper with EPB uses 4 hydraulic service pistons for braking and a dedicated EPB actuator piston, so the Model 3 retains electronic parking-brake function while adding rear thermal capacity.
Why choose carbon-ceramic over iron rotors on this Model 3 Performance?
Carbon-ceramic rotors reduce brake dust and rotating mass while tolerating repeated heat cycles better than iron in high-energy braking. For a Model 3 Performance used for fast street driving or track sessions, the 380mm CCB package targets fade resistance, cleaner wheels, and more stable braking feel.
