2013-2024 Maserati Quattroporte / S / GTS / Trofeo CCB Big Brake Kit — Genuine Alcon RC6 6-Piston Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
This 2013-2024 Maserati Quattroporte kit is for owners who want more heat capacity than the factory brake package, less iron-rotor dust on open 21 inch wheels, and lower rotating mass from carbon-ceramic rotors. The front axle uses a Genuine Alcon RC6 6-Piston Caliper over a 410 mm carbon-ceramic rotor, while the rear uses a TTSPORT EP4 4-Piston Caliper with EPB on a 380 mm rotor so the brake system is engineered as a complete front/rear package. Every kit is built to the confirmed Quattroporte trim, not assumed from the chassis name, so bracket geometry, rotor-hat offset, and caliper position are matched before production.
- 410 mm front carbon-ceramic rotors require 21 inch or larger wheels on this Quattroporte; wheels under 21 inches will not clear the rotor package, and spoke clearance still must be checked.
- The front upgrade uses the exact Genuine Alcon RC6 6-Piston Caliper specified for this kit, paired with StopFlex carbon-ceramic rotors, pads, hats, hardware, and lines.
- The rear package keeps electronic parking-brake function by using the TTSPORT EP4 4-Piston Caliper with EPB on a 380 mm carbon-ceramic rotor.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 410 mm front rotor, so the minimum wheel size is 21". Wheels under 21" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses a Genuine Alcon RC6 6-Piston Caliper, giving the Quattroporte a six-piston fixed-caliper layout for more even pad loading, stronger clamping control, and a firmer pedal under repeated high-energy stops. Alcon is a recognized performance and motorsport brake manufacturer, and this genuine RC6 hardware gives the kit a credible front-caliper foundation instead of an anonymous aftermarket casting. StopFlex matches the caliper position to the customer's confirmed trim, rotor hat, and wheel package.
Rear Caliper (Balance)
The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB, adding real rear service-brake piston area while preserving the Quattroporte's electronic parking-brake function. Its four hydraulic pistons help the rear axle contribute to stability and heat sharing instead of leaving the front brakes to carry the entire upgrade.
Front & rear, engineered together: This kit is engineered as a front/rear system so the 410 mm Alcon-equipped front axle and 380 mm EP4 rear axle work together on bias, thermal capacity, and pedal response. A matched rear upgrade matters on a long, heavy luxury sedan like the Quattroporte because a front-only conversion can increase front heat capacity without giving the rear axle a proportional braking and parking-brake solution.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |

FAQ
Will this kit fit my exact Quattroporte trim?
Fitment is confirmed per vehicle before production. A 2013-2024 Quattroporte, S, GTS, and Trofeo can differ in trim hardware, wheel package, and clearance, so StopFlex matches brackets, rotor-hat offsets, and caliper mounting to the exact year and trim rather than selling a generic platform-wide kit.
What wheel size do I need for the 410 mm front rotor?
The 410 mm front rotor requires 21 inch or larger wheels. Wheels under 21 inches will not clear this front package, and 21 inch wheels still need a spoke-clearance check against the Genuine Alcon RC6 6-Piston Caliper.
Will the electronic parking brake still work?
Yes. The rear package uses the TTSPORT EP4 4-Piston Caliper with EPB, which has hydraulic service pistons for braking and a dedicated EPB actuator piston so factory parking-brake convenience is retained.
Why choose carbon-ceramic instead of another iron brake replacement?
Carbon-ceramic rotors reduce brake dust, cut rotating mass compared with iron rotors, and increase high-temperature stability for repeated stops. On the Quattroporte, that means cleaner open wheels, sharper response from reduced unsprung weight, and more consistent braking when the car is driven hard.
