Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2020-2024 Tesla Model Y (pre-Juniper). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2020-2024 | TTSPORT 8657 6-Piston Forged Caliper / 380mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 19" |
Fitment here is bespoke: brackets, hat offsets, and caliper mounting are engineered for your exact model and trim rather than copied across the platform. Two trims with the same chassis code can still differ in knuckles, hub geometry, and wheel ET clearance — which is why we confirm your trim first, then build the matched system of calipers, pads, rotor hats, floating hardware, and lines for it. Modified knuckles, uprights, or non-factory suspension points require review before ordering.
The 380 mm rotor sets the minimum wheel size at 19" — 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 |
|---|---|
| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |

Why Carbon Ceramic — and Why StopFlex
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.
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.
Winter & Cold-Weather Braking
Cold facts first: an untuned ceramic disc bites less than iron on a freezing morning — physics, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now feels very close to summer. Leave extra margin on the very coldest first stops; severe-climate daily drivers should build Street Spec.
Caliper Overview
Front Caliper
The front uses the TTSPORT 8657 6-Piston Forged Caliper clamping a 380mm carbon-ceramic rotor. Six pistons spread clamping load evenly across a large pad, so pedal feel stays consistent as the Model Y's regen-blended hydraulic braking transitions to full friction stops.
Rear Caliper
The rear runs the TTSPORT EP4 4-Piston Forged Caliper on a 380mm rotor, with four 28mm hydraulic service pistons for braking plus a dedicated 27mm EPB actuator piston that preserves the Model Y's factory electronic parking brake. It's a two-piece forged-aluminum body (about 4.50 kg per caliper without pads) that adds real rear thermal capacity without giving up OE parking-brake function.
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
Before ordering, tell us the exact vehicle, current rotor sizes, and caliper type. Nothing goes to production until the build is confirmed against your VIN-level configuration.
FAQ
Will this fit my exact Model Y trim, including Performance?
Yes, but only after we confirm your trim. The Model Y Performance uses different front knuckle and hub geometry than a Long Range or Standard Range, so the brackets and rotor-hat offsets are cut for your specific car. We do not ship a platform-wide bolt-on and assume it fits every Model Y. Once you confirm the exact trim and build year, the front TTSPORT 8657 mounting and 380mm hat offset are matched to that car.
Does this keep my electronic parking brake working?
Yes. The Model Y uses a factory EPB built into the rear calipers, so the rear TTSPORT EP4 includes a dedicated EPB actuator piston alongside its four hydraulic pistons. You keep normal Hold, Auto Park, and hill-hold behavior while gaining rear-axle thermal capacity from the 380mm carbon-ceramic disc.
How do these behave on a cold winter morning?
An untuned cold carbon-ceramic disc bites less than cold iron on the first stop or two. That is physics, not a defect. We tuned both the low-metallic resin-composite pad (about 0.44 average friction) and the disc's ceramic coating for cold starts, so cold-car feel now comes very close to summer feel. On the coldest first stops, leave a little extra following distance until the system takes its first few applications.
What wheels do I need to clear these brakes?
The 380mm front and rear rotors require a minimum 19-inch wheel, and spoke clearance matters as much as diameter. The stock 20-inch and 21-inch Performance wheels clear easily; if you run smaller aftermarket wheels, send us the specs before ordering so we can verify caliper and spoke clearance.
