Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2017-2025 Volvo S90 Recharge T8. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| T8 | 345mm, 366mm | 320mm, 340mm | 19" |
Keep Your Factory Calipers?
The rule is simple: front factory calipers must be 4-piston or more; the rear has no limit. A 1- or 2-piston floating front setup cannot take direct-replacement discs — that car needs the Full Upgrade kit with calipers. We build to the factory rotor specs above. Aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood) work too — send the caliper model, pad shape, and rotor size for confirmation first.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.

FAQ
Does this kit fit every S90 Recharge T8, or only certain rotor sizes?
It fits the 2017-2025 S90 Recharge T8 only when your factory front rotor is 345mm or 366mm and your rear is 320mm or 340mm. Those are the exact references this page covers. Because the T8 shipped with more than one front disc size across model years and options, you must confirm your actual rotor diameter before ordering — the hats and floating hardware are machined to the specific size, not a universal fit.
Do I keep my factory calipers, and is that safe on a heavy T8?
Yes. This is a Direct Replacement setup: the carbon-ceramic rotors, hats, pads, and floating hardware bolt to your existing Volvo calipers. Direct Replacement is only valid because the S90 Recharge T8's front calipers are 4-piston, which gives enough clamp area and pad footprint to run a carbon-ceramic disc without a caliper change. The rear reuses the factory caliper and works with the electronic parking brake.
How do these brakes behave in cold Scandinavian-style winters?
Straight physics first: a cold carbon-ceramic disc bites a little less than cold iron on the very first stops. That is normal, not a fault. We tuned both the pad compound and the disc's ceramic coating specifically for cold starts, so on the S90 T8 the winter cold-car feel now comes very close to summer feel. On the coldest first stops of the day, leave a little extra following distance until the front rotors take heat — after that they behave like any warmed brake.
The T8 already recovers braking through regen — why upgrade the friction brakes?
Regen only handles light-to-moderate deceleration, and once the hybrid battery can't accept more charge, every hard stop is dumped straight into the friction brakes as heat. On a two-ton-plus S90 T8 that heat load is real, and it's exactly where iron rotors fade and warp. Carbon-ceramic discs hold their friction under repeated heavy stops and shed the heat far better, which is the whole point of running them on a heavy plug-in hybrid.
