Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2010-2018 Audi S8 (D4). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2010-2018 | Akebono OEM Audi S 6-Piston (8N) Caliper / 380mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 19" |
Fitment here is bespoke: brackets, hat offsets, and caliper mounting are engineered for your exact model and trim rather than copied across the platform. Two trims with the same chassis code can still differ in knuckles, hub geometry, and wheel ET clearance — which is why we confirm your trim first, then build the matched system of calipers, pads, rotor hats, floating hardware, and lines for it. Modified knuckles, uprights, or non-factory suspension points require review before ordering.
The 380 mm rotor sets the minimum wheel size at 19" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; 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 |

Why Carbon Ceramic — and Why StopFlex
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.
Long Street-Service Life
In normal road use with matched pads and correct bedding, carbon-ceramic friction surfaces are designed for low wear. Actual service life depends on mileage, contamination, pad choice, heat cycles and driving use.
Low Visible Dust
Matched StopFlex pads are selected for low visible dust on the ceramic friction surface. Actual wheel dust still varies with pad choice, traffic, temperature, bedding and driving intensity.
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.
Short-Fiber or Long-Fiber — Your Call
Every StopFlex disc is true carbon-ceramic. Short-Fiber Street Spec uses a simpler chopped-fiber process for a lower price and street-only duty; the Long-Fiber line uses continuous carbon strands that carry load across the whole rotor for higher strength and thermal durability — the pick for track and race heat.
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 like-size carbon-ceramic rotor can be materially lighter than an iron disc; the exact saving depends on rotor dimensions. Lower rotating, unsprung mass can reduce the load the suspension has to control.
High-Temperature Stability
The carbon-silicon-carbide friction material is selected for high-temperature stability and fade resistance. Overall pedal feel still depends on pad condition, fluid, caliper stiffness, cooling and operating temperature.
Winter & Cold-Weather Braking
Cold-weather trade-off: an untuned carbon-ceramic disc can have less initial bite than cold iron. StopFlex specifies a matched pad compound and ceramic coating tuned to reduce that cold-start gap, but the coldest first stops still deserve extra following distance. Severe-winter daily drivers should choose a Street Spec.
Caliper Overview
Front Caliper
The front axle uses the Akebono OEM Audi S 6-Piston (8N) Caliper with a supplied 380mm rotor. This is a complete upgrade configuration with calipers, rotors, hats, hardware, lines, and matched pads.
Rear Caliper
The rear uses the TTSPORT EP4 4-Piston Forged Caliper integrated with EPB and a supplied 380mm rotor. Its dedicated EPB actuator retains the factory electronic parking-brake function.
Choose Your Rotor: Short-Fiber Street to Long-Fiber Motorsport
Four specs, one rule of thumb: all are real carbon-ceramic discs. Short-Fiber Street Spec is the lower-cost route for street-only driving. The three Long-Fiber specs use continuous carbon strands for higher strength and heat durability, and are the only choice for track-day or motorsport use.
Short-Fiber Street Spec
Chopped short-fiber carbon-ceramic body, ceramic coating, cross-drilled face.
Choose this for street-only use when purchase price matters most. It keeps the carbon-ceramic friction surface and coated finish, but it is not specified for track sessions.
Long-Fiber Street Spec
Continuous long-fiber body, ceramic coating, cross-drilled face, large cooling channels.
Choose this for daily and fast-road use when you want the long-fiber construction without moving to a track-focused face and cooling specification.
Long-Fiber Track-Day Spec
Continuous long-fiber body, ceramic coating, blank face, honeycomb cooling channels.
Choose this for repeated fast-road or track-day braking where thermal duty matters more than the drilled street appearance. High-temperature fluid and appropriate cooling still matter.
Long-Fiber Motorsport Spec
Continuous long-fiber body, uncoated blank face, honeycomb cooling channels.
Choose this for competition-focused use with the corresponding pad, fluid, cooling and warm-up strategy. It is not the default recommendation for a street-driven car.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat still soaks 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.
Get Your Fitment Confirmed
Send the exact year, model, trim, current rotor sizes, caliper type, and wheel details before ordering. StopFlex confirms the supplied configuration before production and requests VIN/build data when needed.
FAQ
Does this kit fit every 2010-2018 Audi S8 (D4)?
Fitment is confirmed to the exact model and trim before build. This listing is for the 2010-2018 Audi S8 (D4) with 380mm front and rear rotors; brackets, hat offsets, and caliper mounting are not assumed to transfer between trims simply because they share the D4 platform. A 19-inch wheel is the minimum, and spoke clearance still requires confirmation.
Will the rear kit keep the factory electronic parking brake?
Yes. The rear TTSPORT EP4 4-Piston Forged Caliper integrated with EPB includes a dedicated electronic parking-brake actuator, so the kit retains factory EPB operation. Confirm the exact vehicle before ordering so the rear mounting, rotor hat offset, and wheel clearance are specified for that S8.
Which StopFlex carbon-ceramic rotor specification should I choose?
Choose Short-Fiber Street Spec for lower-cost street-only use. Long-Fiber Street is the step up for broader road use, while Long-Fiber Track-Day and Motorsport are intended for progressively higher heat and duty requirements. Select from how the S8 is actually driven, then confirm the final rotor specification during the bespoke fitment process.
What should I expect in winter or on the first cold stops?
An untuned cold carbon-ceramic disc can have less initial bite than cold iron. StopFlex specifies a matched pad compound and disc coating to reduce that cold-start gap, but the coldest first stops still deserve extra margin. This is a full 380mm front-and-rear kit, so choose the rotor specification around real seasonal and driving use.
