Read this before you order
This package is built around Brembo GT-R calipers and their matching mounting hardware. It is not a direct-fit carbon ceramic replacement for the factory Supra front caliper. A 380 mm rotor with a 6-piston caliper clears many 19-inch wheels but not all of them, so wheel clearance has to be confirmed before purchase. If you want to keep the OEM front calipers, that's a separate spec.
Why This Upgrade, And What You'll Notice
| STOPFLEX feature | Why it matters on the Supra A90 | What you notice |
|---|---|---|
| 380 x 34 mm carbon ceramic front rotor | The A90 builds heat fast once you drive it hard for more than a quick burst, and that's when the stock front setup starts to fade. | A firmer, more repeatable pedal deeper into a canyon run or a long downhill, with less heat-soak between stops. |
| Carbon ceramic vs. iron at temperature | Iron loses bite as it cooks. STOPFLEX rotors hold useful friction at extreme heat — tested surface friction stays around 0.3μ at 900°C. | Braking that feels the same on your tenth hard stop as your first, instead of a long, soft pedal. |
| About half the weight of a same-size steel rotor | The Supra already responds well to chassis changes, so cutting unsprung mass at the front frees up the suspension. | Lighter, cleaner steering response and less of that heavy, busy feeling over rough pavement. |
| STOPFLEX pads, normal-temp friction over 0.4μ | A big rotor is only half the system; the pad sets cold bite and daily manners for a street-driven Supra. | Strong, predictable bite from cold — normal first-stop behavior even down around -20°C. |
| Low-dust, rust-free ceramic surface | Performance wheels on a Supra show every bit of iron dust, and parked iron rotors rust fast after a wash. | Wheels that stay clean far longer and rotors that don't surface-rust after rain. |
What gets better
- More heat capacity up front for repeated hard stops and long descents.
- Consistent pedal feel through a session instead of fade.
- Less unsprung mass for sharper front-end response.
- Very low brake dust with STOPFLEX pads, so wheels stay clean.
- Rotors that don't rust after rain or a wash.
- Nickel-plated GT-R caliper and reflective ceramic surface for a serious front-corner look.
What to confirm first
- Wheel clearance: 380 mm rotor plus 6-piston caliper against your exact 19-inch wheel barrel, spokes, and offset.
- This is a custom Brembo GT-R front package, not a factory-caliper replacement.
- If you want to keep the OEM front calipers, ask for the direct-fit alternative.
- Pad compound matched to how you actually drive — street, mixed, or track days.
- Rear brakes are optional; decide based on balance, looks, and use.

Supra A90 CCB FAQ
Why run STOPFLEX rotors with Brembo GT-R calipers on a Supra A90?
It pairs a 380mm carbon ceramic front rotor with a high-capacity 6-piston caliper for stronger heat handling and more consistent repeated braking than the factory front setup. It's a custom big brake package, not a direct OEM-style swap.
Will this 380mm front setup fit under 19-inch wheels?
It clears many 19-inch wheels, but not all of them. Barrel shape, spoke design, offset, and the caliper profile all matter. Confirm clearance with a wheel template or fitment check before you order.
Is a carbon ceramic Supra brake upgrade practical for street driving?
Yes, with the right street pad compound. STOPFLEX carbon ceramic rotors run very low brake dust with STOPFLEX pads, don't rust after rain, and give normal cold-stop bite in everyday use.
Do you have to upgrade the rear brakes too?
No. A front upgrade gives the biggest gain in braking capacity and heat handling. Some owners add a matching rear for balance and looks, but it depends on how the car is used.
How long do STOPFLEX carbon ceramic rotors last?
On the street, with no track use, STOPFLEX carbon ceramic rotors can reach roughly 250,000 to 300,000 km. Track use changes wear rate, so lifespan depends on pad choice, temperature, and driving style.
