Audi S4 & RS5 Brake Kits, Rotors & Pads

The S4's turbocharged V6 and the RS5's twin-turbo V6 both make enough power to get these cars onto track days, but the factory brake packages are tuned for street use — repeated hard laps will fade OEM pads and warp OEM rotors faster than most owners expect from a car with this much straight-line performance.

Audi S4 brake kits from Ghost Brakes close that gap with rotors and pads built to hold up under sustained hard braking, not just spirited street driving.

That covers both the sport-sedan S4 and the more track-focused RS5 coupe and Sportback, two cars that share a braking philosophy — enough power to need real fade resistance, whether that power is used on a back road or an actual track day.

Even S4 and RS5 owners who never see a track day put more heat into their brakes than a typical sedan driver simply by using the performance these cars offer on normal roads — spirited on-ramps, mountain passes, and quick highway merges all add up over time.

S4/RS5 Rotors: Fade Resistance for Repeated Hard Stops

Diamond-slotted G11H18 rotors evacuate heat and outgassing far more effectively than OEM castings during back-to-back hard braking zones — the exact scenario where factory rotors on an S4 or RS5 start to show their limits.

Explore the full metallurgy comparison on our drilled & slotted rotor technology page.

On a car with RS5's power-to-weight ratio, rotor warp shows up first as a pulsation through the brake pedal under hard braking from high speed — a symptom S4/RS5 owners on factory rotors report far more often than owners of lower-powered A4 siblings.

That pulsation typically shows up first on the front axle, where quattro AWD and the extra weight of the S4/RS5's turbocharged engine combine to load the front rotors harder than on a comparable rear-drive sport sedan.

Carbon Ceramic Pads That Don't Fade at Track Temperatures

Where OEM semi-metallic pads lose bite as they heat-soak lap after lap, Ghost Brakes carbon ceramic compounds hold consistent friction from a cold morning session to a hot afternoon canyon run.

That consistency matters more on RS5 than most cars in this class — a coupe with this much power and quattro grip generates cornering speeds that put unusual demand on trail-braking performance, not just straight-line stopping distance.

Complete S4 and RS5 Kits

Confirm your exact S4 or RS5 year on the Audi S4 fitment page, then read our bedding procedure before your first track day on the new setup.

Comparing options? See Ghost Brakes vs PowerStop Z36 for a direct look at how our G11H18 rotors stack up against a popular budget alternative.

Every S4/RS5 kit bolts directly to the factory quattro caliper carrier — no spacers, no adapter brackets — so track prep is a standard brake job, not a specialty install requiring a performance shop.

Lifetime Warranty for Street and Track Use

Ghost Brakes S4/RS5 kits carry a lifetime manufacturer warranty and free continental US shipping, whether the car spends its life commuting or turning laps.

Enthusiast-driven S4s and RS5s tend to see more brake wear per mile than an average commuter sedan, which makes a matched, long-life rotor and pad system a better long-term value than repeatedly replacing worn OEM parts every time the factory setup hits its limits.

Choosing the Right Audi S4 / RS5 Brake Kit Tier

Not every Audi S4 / RS5 owner needs the same rotor architecture. Daily drivers who want quieter stops, less dust, and longer rotor life usually land on our 555-tier G11H18 drilled and diamond-slotted one-piece rotors with matched carbon ceramic pads. If you track, tow heavy, or repeatedly brake from highway speed, the 777-tier 2-piece floating front rotor (where offered for your chassis) sheds heat faster and resists warp under repeated thermal cycles.

Use the product grid on this page to filter by your exact year and trim, or open the year-specific fitment tool before you order. Every complete kit ships with hardware, bedding instructions, and a lifetime manufacturing-defect warranty — compare tiers in our 2-piece vs 1-piece rotor guide if you are cross-shopping against OEM or big-box performance brands.

Engineering context for the rotor face design lives on Ghost Brakes diamond-slotted rotors (brand site) — Slyde Over is where you confirm SKU, price, and checkout for your audi s4 / rs5 brake kit.

Audi S4 / RS5 Brake Upgrade: Install, Bedding, and Long-Term Ownership

A matched rotor-and-pad upgrade only pays off if the install and break-in are done correctly. Torque wheel lugs to spec, clean the hub face so the rotor sits flat, and bed the pads using the procedure in our performance rotor break-in guide. Skipping bedding is the most common reason owners blame "pulsation" on new hardware when the pad transfer layer never formed evenly.

For pad compound details — low dust, temperature range, and noise — see carbon ceramic pad technology on Ghost Brakes. On Slyde Over, browse the full brake kit catalog or start from related category kits when you already know your part number.

Frequently Asked Questions

What rotors come in a Audi S4 / RS5 brake kit?

Ghost Brakes Audi S4 / RS5 kits include G11H18 metallurgy drilled and diamond-slotted rotors with GEOMET coating, matched to carbon ceramic pads for direct OEM bolt-on fitment on Audi Audi S4 / RS5 applications.

Do I need to upgrade Audi S4 / RS5 brake pads?

If you track or canyon-run an S4 or RS5, OEM semi-metallic pads fade and wear quickly. Ghost Brakes carbon ceramic pads resist fade, produce less dust, and last 3–5x longer than factory pads.

Are Audi S4 / RS5 brake kits direct bolt-on?

Yes. Ghost Brakes Audi S4 / RS5 brake kits use factory caliper fitment with no modifications required. Confirm year and trim in the product grid below.
