The build: what's actually on the car
| Item | Specification |
|---|---|
| Vehicle | Bentley Continental GT |
| Front calipers | Factory 10-piston fixed calipers (retained) |
| Front rotors | STOPFLEX carbon ceramic, 420 x 40 mm |
| Rear rotors | STOPFLEX carbon ceramic, 380 x 30 mm |
| Upgrade format | Direct-fit rotor replacement keeping the factory brake layout |
| Quoted weight saving | Roughly 30 kg total off the rotor package |
Confirm this before you order
This is a rotor-only setup for Continental GT cars running the factory 10-piston front calipers and the brake layout shown here. Not every Continental GT uses the same package, so check your caliper count and current rotor dimensions on the car instead of going by model name alone.
What carbon ceramic changes on a Continental GT
| STOPFLEX feature | Why it matters on the Continental GT | What you notice |
|---|---|---|
| About half the weight of a same-size steel rotor | The GT is a heavy grand tourer, and the rotor is one of the heaviest spinning parts at each corner. Pull weight there and you cut unsprung and rotating mass without touching the rest of the car. | Suspension that settles quicker over sharp bumps and steering that feels a touch cleaner, especially on a broken back road. |
| Wider fade tolerance than iron under repeated heat | This car covers ground fast and gets asked to slow from real speed, again and again. Iron discs lose their edge as they heat-soak; carbon ceramic holds up better through that cycle. | More predictable pedal on a long mountain descent or a quick run when you're not babying it. |
| Friction over 0.4μ at normal temps with STOPFLEX pads | You want the brakes to feel right from the first cold stop, not just when they're warm. Strong cold-to-warm friction keeps the pedal honest in daily driving. | Confident, progressive bite pulling out of the driveway and in traffic. |
| No rust after rain, very low dust with STOPFLEX pads | On a car with wheels this expensive, brake grime and the orange rust film on parked iron discs are a real annoyance, not a footnote. | Cleaner spokes between washes and no rust ring after the car sits out wet. |
What gets better
- Lower unsprung mass at all four corners from much lighter rotors
- Steadier pedal feel through repeated hard stops and long descents
- Very low brake dust when paired with STOPFLEX pads, so wheels stay cleaner
- No surface rust after rain, unlike factory iron discs
- Long street life, with STOPFLEX quoting roughly 250,000 to 300,000 km off-track
What to confirm first
- That your car runs the factory 10-piston front calipers shown here
- Your current front and rear rotor dimensions against 420x40 mm and 380x30 mm
- This is a rotor-only upgrade, not a full big-brake caliper conversion
- Pad pairing: run STOPFLEX pads to get the low-dust and friction behavior described

FAQ
Do I have to swap the factory calipers on a Bentley Continental GT?
No. This is a rotor-only upgrade for Continental GT cars running the factory 10-piston front calipers and the original brake layout. The calipers stay put, so you keep the OEM hardware concept and just change the discs to carbon ceramic.
What rotor sizes does this STOPFLEX upgrade use?
The build shown here runs 420 x 40 mm carbon ceramic rotors up front and 380 x 30 mm carbon ceramic rotors at the rear for the Bentley Continental GT application featured in this article.
Will carbon ceramic rotors make the Continental GT ride harsher?
It works the other way. Carbon ceramic rotors weigh far less than the steel or iron discs they replace, which cuts unsprung mass. On a heavy GT like the Continental, that helps the suspension settle more cleanly over sharp bumps and sharpens steering feel.
Are STOPFLEX carbon ceramic brakes fine for normal street driving?
Yes. STOPFLEX carbon ceramic rotors are built for everyday road use and pair with street-focused pads for clean, progressive braking. They don't rust after rain and produce very low brake dust when run with STOPFLEX pads.
How long can STOPFLEX carbon ceramic rotors last on the street?
On the street, STOPFLEX puts rotor life at roughly 250,000 to 300,000 km when the car isn't tracked. Real-world life still comes down to how you drive, which pads you run, and the conditions you see.
