2017-2025 Volvo S90 CCB Big Brake Kit — Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper Front Brake Upgrade
The 2017-2025 Volvo S90 is a heavy SPA-platform sedan, and owners shopping this kit are usually trying to reduce front brake heat, pad dust, and repeated iron-rotor service without giving up daily drivability. This StopFlex front upgrade pairs 390mm carbon-ceramic rotors with the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper to increase thermal capacity and clamp control at the axle doing most of the braking. Each kit is built to the confirmed S90 trim, wheel package, and hub geometry, with trim-specific brackets, rotor hats, hardware, pads, and lines.
- 390mm front carbon-ceramic rotors require 20 inch or larger wheels on the 2017-2025 Volvo S90; spoke clearance must be checked before the kit is built.
- The front axle uses the exact Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, not a generic six-piston casting.
- The kit is front-only for this option and is engineered around the customer’s confirmed S90 trim, drivetrain, wheel offset, and brake configuration.

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 390 mm front rotor, so the minimum wheel size is 20". Wheels under 20" 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 caliper is the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper, a factory performance Brembo unit selected for its six-piston clamp distribution across a large front pad. On the S90, that piston layout helps stabilize pedal response as the 390mm carbon-ceramic rotor absorbs repeated high-speed stops. Its OEM-derived Brembo construction gives the kit a known performance-caliper foundation instead of an unproven universal casting.
Rear Caliper (Balance)
This kit option is front-only; no rear caliper is included. A rear carbon-ceramic package can be matched on request if the build requires rear visual balance, revised rear thermal capacity, or full-vehicle brake tuning.
Front & rear, engineered together: StopFlex does not treat the S90 as a platform-wide bolt-on because rear brake hardware, electronic parking brake packaging, wheel clearance, and trim configuration affect the final balance. For a front-only 390mm conversion, the rotor diameter, pad compound, hydraulic behavior, and caliper position are specified so the front upgrade works with the factory rear system rather than overpowering it.
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 390mm kit fit my exact 2017-2025 Volvo S90 trim?
Fitment is not assumed from the S90 chassis name. StopFlex confirms your exact year, trim, drivetrain, factory brake package, hub geometry, wheel diameter, wheel offset, and spoke clearance before machining brackets and rotor hats for the car.
What wheel size do I need for the 390mm front rotor?
The 390mm front rotor requires 20 inch or larger wheels. Diameter alone is not enough; the Genuine Brembo OEM Ford Shelby GT350 Mustang 6-Piston Caliper also needs spoke clearance, so wheel offset and spoke shape must be verified before ordering.
Does this front-only kit affect the Volvo S90 electronic parking brake?
The S90 uses a factory electronic parking brake at the rear, and this kit option does not replace the rear caliper. The front upgrade is engineered to work with the factory rear brake and EPB system unless a matched rear package is ordered separately.
Why choose carbon-ceramic brakes instead of another iron rotor setup on an S90?
Carbon-ceramic rotors reduce brake dust and rotating mass compared with iron, and they handle repeated heat cycles without the same front-rotor wear pattern many heavy luxury sedans see in hard road use. This kit adds a 390mm front rotor and six-piston Brembo clamp control for drivers who want more heat capacity without moving to a track-only brake setup.
