Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2008-2016 Audi RS5 (B8). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2008-2016 | Akebono OEM Audi RS 6-Piston (9N) Caliper / 400mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 20" |
This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review before ordering.
The 400 mm rotor sets the minimum wheel size at 20" — 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 |

| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |

Why Carbon Ceramic — and Why StopFlex
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.
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.
Winter & Cold-Weather Braking
On a freezing start, carbon-ceramic friction can feel different from warm operation. StopFlex pairs the disc coating with its matched street pad to improve cold response; it is still prudent to leave extra margin for the first stops in severe cold. Use a Street Spec for harsh-winter daily service.
Caliper Overview
Front Caliper
The Akebono OEM Audi RS 6-Piston (9N) Caliper is supplied for the 400mm front configuration. This is a full upgrade kit, not a factory-caliper retention option.
Rear Caliper
The TTSPORT EP4 4-Piston Forged Caliper integrated with EPB is supplied with the 380mm rear configuration. Its dedicated EPB actuator retains electronic parking-brake operation.
Choose Your Rotor: Short-Fiber Street to Long-Fiber Motorsport
Left to right is ascending duty. Short-Fiber Street Spec keeps carbon-ceramic benefits at a lower price for street use only; the Long-Fiber Street, Track-Day, and Motorsport specs add continuous-fiber strength and thermal durability for everything from daily premium builds to race weekends.
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
Before ordering, provide the exact vehicle, current rotor sizes, caliper type, and wheel details. Production starts only after the configuration is confirmed; VIN/build data is requested when it is needed to resolve fitment.
FAQ
Does this kit fit every 2008–2016 Audi RS5 (B8)?
It is listed for the 2008–2016 Audi RS5 (B8), but final fitment is bespoke to the confirmed model and trim. The 400mm front rotor, brackets, hat offsets, and caliper mounting are not assumed to transfer between trims simply because they share the B8 platform. Confirm the exact vehicle before ordering.
Which rotor specification should I choose for my RS5?
Choose Short-Fiber Street Spec only for lower-cost street use. Long-Fiber Street is the step up for regular road driving, while Long-Fiber Track-Day and Motorsport are for progressively higher heat and duty requirements. Select based on how the RS5 is actually used rather than choosing a track-focused disc for a street-only car.
What wheel clearance is required for the 400mm front setup?
The 400mm front configuration requires a minimum 20-inch wheel according to the fitment chart. Diameter alone is not enough: spoke profile and wheel offset still need physical clearance confirmation around the Akebono OEM Audi RS 6-Piston (9N) Caliper.
What should I expect from carbon-ceramic brakes in cold winter conditions?
An untuned cold carbon-ceramic disc can have less initial bite than cold iron. This kit uses a matched pad compound and disc coating intended to reduce that cold-start gap, but the first stops in the coldest conditions still deserve extra margin. Do not expect identical cold and warm operating behavior.
