The Bentley Continental GT is the definitive Grand Tourer, combining effortless W12 or V8 power with supreme luxury. However, stopping a 2,200 kg (4,850 lb) missile from 300 km/h requires massive thermal capacity. The factory 420mm iron rotors are effective but incredibly heavy, compromising the air suspension's ability to filter out bumps. This case study details the StopFlex Carbon-Ceramic Rotor Upgrade—a direct-fit solution that transforms ride quality and braking endurance.
The Struggle
Even the ultimate GT car has room for improvement. The standard iron braking system presents three key issues:
- Unsprung Mass: The 420mm front iron rotors weigh over 18kg each. This immense rotating mass works against the suspension, creating impact harshness over sharp bumps and dulling steering response.
- Brake Dust: The factory pads generate copious amounts of black dust, requiring constant cleaning to keep the intricate 21/22-inch wheels looking presentable.
- Thermal Fade: Repeated high-speed stops can saturate the iron rotors, leading to a soft pedal and reduced confidence during spirited driving.
Technical Specification
This is a Direct-Fit Rotor Upgrade designed to work seamlessly with the factory massive 10-piston front calipers, fitting perfectly inside the factory wheels.
| Vehicle | Bentley Continental GT |
|---|---|
| Front Calipers | Factory 10-Piston Fixed |
| Front Rotors | StopFlex C/SiC (420 x 40 mm) |
| Rear Rotors | StopFlex C/SiC (380 x 30 mm) |
| Weight Saving | ≈ 30 kg (66 lbs) Total Reduction |
Compatibility Redline
This rotor-only swap is strictly engineered for Bentley Continental GT models equipped with the factory Calipers. It is designed to replace the standard 420mm iron rotors. Please verify your factory rotor size before ordering.
Engineering Validation
1. "Magic Carpet" Ride Improvement
Our carbon-ceramic discs are over 50% lighter than the factory iron rotors. Removing nearly 30 kg of unsprung mass allows the air suspension to react significantly faster to road imperfections. The result is a smoother, more composed ride that crashes less over potholes, enhancing the Bentley's core luxury mission.
2. Unwavering Stopping Power
StopFlex ceramics provide the thermal capacity to handle repeated stops from V-Max speeds without fade. The friction coefficient remains stable even at temperatures exceeding 800°C, ensuring that you have maximum braking power available instantly, whether on the Autobahn or a mountain pass.
3. Pristine Cleanliness
For a Bentley, appearance is everything. Our low-dust ceramic pad formulation keeps your wheels pristine, eliminating the corrosive black dust that plagues factory pads. Additionally, the corrosion-proof rotors prevent unsightly rust rings from forming after washing or rain.
4. Direct-Fit Simplicity
This system retains the factory calipers, which are excellent engineering pieces. By upgrading the friction ring to carbon-ceramic, we unlock the full potential of the factory hardware without the complexity or cost of replacing the entire braking system.

In-Depth Bentley FAQ
Q: Do I need to change my factory calipers?
No. The factory 10-piston calipers are massive and extremely capable. Our rotors are engineered with custom hats to be a direct, bolt-on replacement for the factory iron discs, allowing you to retain your original calipers and parking brake functionality.
Q: Will this make the ride harsh?
Quite the opposite. By removing nearly 30 kg of unsprung weight from the corners of the car, the suspension works more efficiently. The wheels can track the road surface better, resulting in a ride that feels "lighter on its feet" and more compliant over sharp bumps.
Q: Is this system noisy?
No. While early carbon-ceramic systems had a reputation for noise, our StopFlex system is engineered for refined street performance. Our pads are formulated to provide smooth, progressive engagement without the squeal often associated with track-focused ceramics.
Q: What is the lifespan of these rotors?
For a luxury GT car, StopFlex long-fiber rotors are effectively a "lifetime" component. They are chemically inert and do not rust or wear down like iron rotors, potentially outlasting the vehicle's ownership period under normal driving conditions.
Q: Does this eliminate brake dust?
Yes. The ceramic pad compound produces virtually zero dust. This is a major benefit for owners who want their complex alloy wheels to remain clean between details.
