2017-2025 Volvo S90 CCB Big Brake Kit — Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper Front Brake Upgrade
The 2017-2025 Volvo S90 is a heavy SPA-platform sedan, and repeated high-speed stops can expose the heat limits, dust output, and mass of the factory iron front brakes. This StopFlex front kit replaces the front axle hardware with 380mm carbon-ceramic rotors and a Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper package for higher thermal capacity, lower unsprung weight, and cleaner open-wheel presentation. Brackets, rotor-hat offsets, lines, and caliper mounting are engineered to the buyer’s exact S90 trim rather than assumed from the shared Volvo SPA chassis.
- 380mm front carbon-ceramic rotors require 19-inch or larger wheels on the Volvo S90, with spoke clearance verified before build.
- The front upgrade uses the Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper with StopFlex carbon-ceramic rotors, pads, hats, hardware, and lines.
- S90 T5, T6, and T8 Recharge trims can differ in weight, drivetrain packaging, wheel offsets, and brake clearances, so StopFlex confirms the exact trim before producing brackets and hats.

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.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses the Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper, giving the S90 a rigid six-piston performance caliper matched to a 380mm rotor. AP Racing is a known motorsport brake manufacturer, and the Radi-CAL II architecture is selected here for consistent clamp control, pedal response, and heat management under repeated braking. StopFlex matches the caliper mounting position, hose routing, and rotor centerline to the confirmed S90 trim and wheel package.
Rear Caliper (Balance)
This kit option is front-only; no rear caliper is included. A rear carbon-ceramic match can be specified on request when the customer wants coordinated rear appearance, rear rotor mass reduction, or EPB-compatible rear hardware planning.
Front & rear, engineered together: Front brake torque must be planned around the S90’s rear axle and stability-control behavior, not just maximum front rotor size. StopFlex confirms piston area, pad compound, rotor diameter, and rear-brake configuration so the 380mm front upgrade does not create an avoidable front-biased mismatch.
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 380mm front kit fit my exact 2017-2025 Volvo S90 trim?
StopFlex builds the kit after confirming your S90 year, trim, drivetrain, hub and knuckle details, wheel diameter, wheel offset, and spoke clearance. The brackets and rotor-hat offsets are produced for your confirmed car, not assumed from the SPA platform name.
What wheel size is required for the Volvo S90 380mm front rotor?
The 380mm front rotor requires 19-inch or larger wheels. Wheel diameter alone is not enough; the Genuine AP Racing CP9560 Radi-CAL II 6-Piston Caliper also needs spoke clearance, so StopFlex verifies your wheel specs before production.
Does this front-only kit affect the S90 electronic parking brake?
The factory S90 electronic parking brake is on the rear brake system, and this kit option upgrades the front axle only. Rear EPB retention becomes part of the engineering review only if you request a matching rear carbon-ceramic package.
Why choose carbon-ceramic front brakes instead of another iron rotor setup?
Carbon-ceramic rotors reduce unsprung mass, cut brake dust, and tolerate repeated heat cycles better than typical street iron rotors. On a Volvo S90 used for fast road driving, mountain descents, or occasional track sessions, the 380mm front rotor and AP Racing six-piston caliper address front-axle heat and pedal consistency first.
