2016-2026+ Tesla Model X / Performance / Plaid CCB Big Brake Kit — Genuine Brembo GT BM6 6-Piston Caliper Front + Genuine Brembo GT BM4 4-Piston Caliper Rear Setup
The 2016-2026+ Tesla Model X is heavy, quick, and regen-biased, so the friction brakes may see long periods of light use followed by high-energy stops that expose heat, corrosion, dust, and pedal consistency issues. This StopFlex kit replaces the factory iron setup with 380 mm carbon-ceramic rotors at all four corners, Genuine Brembo GT BM6 6-Piston Calipers in front, and Genuine Brembo GT BM4 4-Piston Calipers in rear. Each order is engineered for the confirmed Model X, Performance, or Plaid trim so bracket geometry, rotor-hat offset, caliper position, and wheel clearance match the actual car.
- Uses 380 mm front and 380 mm rear carbon-ceramic rotors; 19-inch wheels are the minimum wheel diameter, and spoke clearance must still be checked before production.
- Front upgrade is the exact Genuine Brembo GT BM6 6-Piston Caliper, selected for higher clamp control and pedal stability than the factory four-piston Model X front brake layout.
- Built for Model X, Performance, and Plaid trim confirmation because Tesla Model X variants can differ in wheel package, hub geometry, knuckle/upright detail, and brake clearance.

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 GT BM6 6-Piston Caliper, which spreads pad load through six pistons for controlled clamping force and a firmer pedal under repeated high-energy stops. Brembo GT hardware gives this Tesla Model X kit a known performance-brake foundation instead of an unbranded caliper, with a rigid fixed-caliper construction suited to carbon-ceramic rotor use. The caliper is positioned with StopFlex trim-specific brackets and hat offsets rather than assumed from the Model X platform name.
Rear Caliper (Balance)
The rear axle uses the Genuine Brembo GT BM4 4-Piston Caliper with a matching 380 mm carbon-ceramic rotor so rear torque contribution stays part of the engineered brake balance. The Model X factory electronic parking brake is accounted for during configuration so parking-brake and Auto Hold requirements are confirmed before production.
Front & rear, engineered together: This kit is engineered as a front-and-rear system so the 6-piston front and 4-piston rear calipers work with matched rotor diameter, pad selection, hat offset, and hydraulic balance. A four-corner package avoids the front-only mismatch that can change brake bias, ABS intervention behavior, and stability during repeated deceleration in a heavy AWD EV.
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 Model X, Performance, or Plaid?
Fitment is confirmed per order, not assumed from the Model X chassis name. StopFlex engineers the brackets, rotor-hat offsets, caliper mounting, and line routing for your exact year, trim, wheel package, and brake configuration.
What wheel size do I need for the 380 mm carbon-ceramic rotors?
The largest rotor in this kit is 380 mm, so wheels under 19 inches will not clear it. A 19-inch or larger wheel still needs a spoke-clearance check because the Genuine Brembo GT BM6 front caliper occupies more radial and lateral space than the factory caliper.
Will the electronic parking brake and Auto Hold still work?
The Tesla Model X uses an electronic parking brake, so the rear configuration is reviewed before production to preserve the required parking-brake function. StopFlex confirms the rear setup against the customer's exact Model X trim and brake layout before building the kit.
Why switch a Model X to carbon-ceramic brakes?
Carbon-ceramic rotors reduce rotating and unsprung mass compared with iron, produce far less visible brake dust, and tolerate repeated heat cycles better during mountain driving, towing-style loads, or track use. On a heavy Plaid or Performance Model X, the main payoff is consistent friction braking when regen alone cannot manage the stop.
