Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2016-2026+ Tesla Model X. This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2016-2026+ | Akebono OEM Audi RS 10-Piston (10N) Caliper / 420mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 21" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review before ordering.
The 420 mm rotor sets the minimum wheel size at 21" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |

| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |

Why Carbon Ceramic — and Why StopFlex
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Caliper Overview
Front Caliper
The front uses the Akebono OEM Audi RS 10-Piston (10N) caliper, a factory-supplied unit with ten opposed pistons for even pad loading and a firm, repeatable pedal on a heavy SUV. It clamps a 420 mm carbon-ceramic front rotor, so the kit requires a 21-inch minimum wheel.
Rear Caliper
The rear is the TTSPORT EP4 4-Piston Forged Caliper with integrated EPB: four 28 mm hydraulic service pistons plus one 27 mm dedicated actuator piston that keeps the Model X's factory electronic parking brake fully functional. The two-piece forged-aluminum body weighs about 4.50 kg without pads and adds real rear-axle thermal capacity on a 380 mm rotor.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.
Get Your Fitment Confirmed
Send the exact vehicle details, current rotor sizes, and caliper type before ordering. Every StopFlex order is confirmed against your VIN-level configuration before production.
FAQ
How does this kit behave in cold weather and winter driving?
An untuned carbon-ceramic disc bites less than cold iron on the first stops of a cold morning — that is normal physics, not a fault. StopFlex tunes both the low-metallic resin-composite pad compound and the disc's ceramic coating specifically for cold starts, so on the Model X cold-car pedal feel comes very close to a warm summer stop. On the coldest first stops, leave a little extra following distance until the front 420 mm rotors take heat, then bite is consistent.
Will this kit clear my wheels and fit my exact Model X trim?
The 420 mm front rotor sets a hard 21-inch minimum wheel size, and spoke clearance matters as much as diameter, so confirm your wheel before ordering. This kit is bespoke-engineered per confirmed trim: brackets, rotor-hat offsets, and caliper mounting are cut for your specific Model X, including Plaid, since hub geometry and wheel ET can differ across the lineup. We do not sell it as a platform-wide bolt-on.
Does the kit keep my electronic parking brake working?
Yes. The rear TTSPORT EP4 caliper includes a dedicated 27 mm EPB actuator piston separate from its four hydraulic pistons, so your Model X keeps full factory electronic parking-brake function — hold, auto-engage, and hill assist all work as delivered while you gain rear-axle thermal capacity on the 380 mm rotor.
Is carbon ceramic worth it on a heavy SUV like the Model X Plaid?
The Model X is one of the heaviest, most powerful SUVs on the road, and the Plaid loads the brakes far harder than the mass-market system was designed for. Carbon-ceramic rotors cut unsprung and rotating mass, resist fade under repeated hard stops, and shed the iron dust that coats wheels. The pad compound runs an average friction coefficient near 0.44 with heat resistance to about 750 °C and strong anti-fade behavior, which is what repeatable stopping on a 5,000-lb+ vehicle needs.
