2017-2025 Volvo S90 CCB Big Brake Kit — Genuine Brembo GT6 Front Brake Upgrade
The 2017-2025 Volvo S90 is a heavy luxury sedan, so repeated high-speed braking and open-wheel daily driving expose the limits of factory iron rotors: heat buildup, brake dust, and mass at the front axle. This StopFlex front CCB kit pairs a 380 mm carbon-ceramic rotor with Brembo V6 / GT6 / GTS6 6-Piston Caliper Options to add heat capacity and fade resistance while reducing rotating and unsprung weight. Each kit is built only after the exact S90 year, trim, drivetrain, and wheel clearance are confirmed, so the brackets, hats, and caliper position are matched to that car rather than assumed from the chassis name.
- 380 mm front carbon-ceramic rotors require 19-inch or larger wheels on the 2017-2025 Volvo S90; spoke clearance is checked separately before the kit is built.
- Front caliper choices are V6, GT6, or GTS6 6-piston Brembo options, each paired with the same 380 mm StopFlex front CCB rotor package.
- The S90 uses an electronic parking brake from the factory, so this front-only kit leaves the rear EPB hardware unchanged unless a rear matching package is requested.

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 380 mm front rotor, so the minimum wheel size is 19". Wheels under 19" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |

| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |
Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front upgrade uses Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, giving the S90 a six-piston fixed-caliper layout for more even pad loading and a firmer, more controlled pedal response than a smaller sliding factory caliper. The buyer chooses the exact front option: V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper with 380 mm rotor; GT6 = Genuine Brembo GT | M6 6-Piston Caliper with 380 mm rotor; GTS6 = Genuine Brembo GT | S6 6-Piston Caliper with 380 mm rotor. Each option uses a genuine Brembo performance caliper with StopFlex carbon-ceramic rotors, matched hats, pads, hardware, and lines for the confirmed S90 trim.
Rear Caliper (Balance)
This kit option is front-only; no rear caliper is included. A rear-matched package can be specified on request to coordinate rear brake torque, parking-brake requirements, and visual balance.
Front & rear, engineered together: The front 380 mm CCB package is engineered around the S90’s confirmed trim so front brake torque, rotor offset, and caliper placement do not create a generic front-only mismatch. If the buyer wants a full front/rear conversion, StopFlex can match the rear hardware to the same vehicle data instead of relying on platform-wide assumptions.
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 StopFlex kit fit my exact 2017-2025 Volvo S90 trim?
Fitment is confirmed per car, not by S90 platform name alone. StopFlex verifies the exact year, trim, drivetrain, hub geometry, wheel size, wheel offset, and spoke clearance before building the brackets, rotor hats, and caliper mounting for the 380 mm front kit.
What wheels do I need for the 380 mm Brembo front setup?
The 380 mm front carbon-ceramic rotor requires 19-inch or larger wheels. Diameter is only the first check; the Brembo V6 / GT6 / GTS6 6-piston caliper also needs enough spoke clearance, so wheel model, width, offset, and brake-template clearance should be confirmed before ordering.
Will the Volvo S90 electronic parking brake still work?
Yes, for this front-only kit the rear parking-brake hardware is not replaced, so the factory S90 electronic parking brake remains on the rear axle. If a rear-matched package is requested, EPB compatibility is handled as part of the rear brake specification.
Why choose carbon-ceramic over factory iron brakes on an S90?
Carbon-ceramic rotors reduce brake dust and rotating mass while adding heat stability for repeated highway-speed stops or aggressive mountain driving. On this S90 kit, the 380 mm front rotor and genuine Brembo 6-piston caliper are selected to improve front-end thermal capacity without using a generic off-the-shelf platform fitment.
