The build: front kit and fitment
| Component | STOPFLEX front build |
|---|---|
| Vehicle | Tesla Model Y |
| Front calipers | Brembo GTS6, 6-piston fixed |
| Front rotors | STOPFLEX C/SiC carbon ceramic, 405 x 34 mm |
| Pads | STOPFLEX low-dust ceramic compound |
| Wheel requirement | 20-inch wheels for barrel clearance |
| Axle scope | Front big brake upgrade |
| Rotor weight | About half the weight of a same-size steel rotor |
Check this before you buy
This is a custom front big brake kit. The 405mm STOPFLEX rotor is matched to the Brembo GTS6 caliper with dedicated mounting hardware, and it generally needs a 20-inch wheel to clear the caliper. Running 19-inch Gemini wheels? This exact setup won't fit, so confirm wheel size first.
Why CCB makes sense on a heavy EV
| STOPFLEX feature | Why it matters on a Model Y | What you notice |
|---|---|---|
| 405mm carbon ceramic rotor + 6-piston caliper | The Model Y is quick and heavy, so the moment regen hands off, the front axle carries the real load in a hard stop. | Firmer, more repeatable braking when you stand on the pedal, instead of fade after a few hard stops. |
| Rotor about half the weight of steel | Big iron rotors add unsprung mass right where the suspension is trying to react to the road. | Cleaner steering response and a more settled front end over broken pavement. |
| No rust after rain exposure | On an EV, regen means the friction brakes often sit unused, so iron rotors surface-rust between drives. | No gritty grinding on the first few stops of a damp morning. |
| Low-dust STOPFLEX pads | Light factory wheels show iron brake dust fast, and nobody enjoys scrubbing it off. | Wheels that stay clean far longer between washes. |
| Long-fiber CCB construction | Daily-driven street cars need durability, not a consumable track rotor. | Street life of roughly 250,000 to 300,000 km when the car isn't tracked. |
What gets better
- More heat capacity and consistency under repeated hard stops
- Lower unsprung mass for sharper wheel control
- Rust-free rotor faces, even after rain
- Very low brake dust with STOPFLEX pads
- Quieter first stops than unused iron rotors
What to confirm first
- Wheel size: this kit needs 20-inch wheels, not 19-inch Gemini
- Scope: this is a front-axle upgrade
- Hardware: rotor, caliper, and brackets match as one system
- Goal fit: best for street confidence and clean wheels, not a stripped track build

Model Y brake upgrade FAQ
If regen does most of the braking, why upgrade the friction brakes on a Model Y?
Regen handles gentle, everyday slowing, but it steps aside when you need maximum stopping force right now: a panic stop, repeated hard braking, or a long downhill with the car loaded. That's all on the friction brakes. On a heavy EV, a bigger front package adds heat capacity and keeps pedal feel consistent when it counts.
Will carbon ceramic brakes make my Model Y noisy or harsh to drive?
No. This setup is tuned for refined street control, not a race-car bite. STOPFLEX pads run very low dust, and the carbon ceramic rotors don't rust after rain, so you avoid the gritty first-stop grinding many EV owners get from iron rotors that sit unused while regen does the work.
Will this 405mm front kit fit 19-inch Model Y Gemini wheels?
No. The 405mm rotor and Brembo GTS6 caliper generally need a 20-inch wheel for barrel clearance. If your Model Y runs 19-inch Gemini wheels, look at a smaller brake package instead, and confirm clearance before you order.
How long do STOPFLEX carbon ceramic rotors last on a street-driven Model Y?
On the street, with no track use, STOPFLEX carbon ceramic rotors can reach roughly 250,000 to 300,000 km. On an EV it can be even easier on them, since regen takes a lot of the daily load off the friction brakes, and the rotors never suffer rust-related surface corrosion.
