Case summary
The Maserati Ghibli utilizes a rear-wheel-drive bias chassis with strong dynamic potential. However, the factory iron brake system struggles with thermal saturation and non-linear pedal feel during aggressive driving or track use. The objective for this build was a complete, systematic reconstruction of the vehicle's braking limits. The solution integrated Alcon RC6 front calipers, TTSPORT EP4 rear calipers, and StopFlex carbon-ceramic rotors to maximize thermal capacity, eliminate brake fade, and stiffen pedal response without triggering electronic parking brake (EPB) errors.

What usually becomes the limit on a Maserati Ghibli
The primary limit is thermal mass. During continuous hard braking, the OEM iron rotors absorb heat faster than they can dissipate it. As temperatures climb, pad friction decreases and the pedal develops a spongy, inconsistent stroke. This robs the driver of predictable modulation.
Aesthetics also drive upgrades on this platform. The factory calipers and iron rotors look undersized behind large 21-inch wheels. Upgrading to a carbon-ceramic package eliminates the heavy black brake dust typical of standard pads and provides a brighter, more aggressive visual presence that fills the wheel barrel.
Upgrade recommendation (Maserati Ghibli-specific)
For a complete structural upgrade that maintains daily drivability while solving thermal limits, we recommend a hybrid caliper setup:
- Front Axle: A rigid multi-piston caliper (like the Alcon RC6) paired with 410 mm (16.1 in) StopFlex CCB rotors for maximum bite and heat dissipation.
- Rear Axle: An integrated-EPB caliper (like the TTSPORT EP4) paired with 380 mm (15.0 in) StopFlex CCB rotors. This balances the hydraulic bias and retains factory parking brake functionality without external brackets.
What we changed and why
- Front Calipers: Installed Alcon RC6 (6-piston) units. The opposed piston layout ensures uniform pressure across a larger pad surface. This eliminates uneven pad wear and delivers a highly linear, immediate pedal response compared to the factory setup.
- Rear Calipers: Installed TTSPORT EP4 (4-piston) units. This caliper features an integrated electromechanical parking brake. It syncs directly with the Maserati's factory protocols, avoiding dashboard error codes while increasing rear clamping force.
- Rotors: Installed StopFlex carbon-ceramic rotors—410 mm (16.1 in) front and 380 mm (15.0 in) rear. This setup sheds massive rotating unsprung weight, improving suspension agility. The CCB material maintains a stable friction coefficient at temperatures exceeding 1,300°C (2,370°F), effectively eliminating brake fade.
- Friction Material: Installed StopFlex CCB-specific performance ceramic pads to match the rotor's thermal characteristics and ensure low dust output.
OEM steel vs StopFlex carbon-ceramic (case view)
| Metric | OEM Iron Setup | Alcon/TTSPORT + StopFlex CCB |
|---|---|---|
| Thermal capacity | Prone to heat soak under continuous load | High; maintains friction targets at extreme temperatures |
| Pedal feel stability | Softens as heat builds; non-linear | Firm, highly linear, and predictable |
| Unsprung mass | Standard baseline weight | Significantly lower; improves suspension response |
| Wheel-view appearance | Produces heavy dust; looks small in 21-inch wheels | Aggressive stance filling the barrel; virtually dust-free |
| Disc surface finish | Standard iron grain | StopFlex proprietary coating formula improves smoothness and reflectivity (final look depends on wheel design, lighting, and photo exposure) |

FAQ
Why use the TTSPORT EP4 caliper on the rear axle?
The TTSPORT EP4 integrates the electromechanical parking brake directly into the caliper body. This eliminates the need for clumsy dual-caliper setups or external brackets, ensuring the factory parking brake functions normally without throwing dashboard error codes.
Will this 410 mm (16.1 in) front and 380 mm (15.0 in) rear setup fit my Ghibli?
This massive rotor and caliper combination requires a minimum 21-inch wheel to ensure proper barrel clearance. It will not clear factory 19-inch or 20-inch wheel options.
How does the Alcon RC6 change the pedal feel?
The 6-piston architecture provides a much stiffer mechanical bite. It eliminates the spongy travel often found in the factory system, offering immediate response upon initial application and highly linear modulation as you increase pedal pressure.
