Why Rear Spoilers Matter on the S5 B8.5

The Audi S5 B8.5 (2013–2016) is already a visual upgrade over the A5 or S4. Wide hips, sharp headlights, coupe proportions. But let’s be honest—the rear end is too soft from factory. If you’re rocking quad exhausts and an aggressive diffuser, the trunk lip needs to match the energy.

Enter: carbon fiber spoilers.

They add style, balance out the rear, and give your coupe that planted, widebody silhouette. Bonus: they install in under 30 minutes, no drilling required.

This guide ranks the Best Carbon Fiber Rear Spoilers for the Audi S5 B8.5, so you can find the perfect one based on your build goals.

1. V-Style Carbon Fiber Spoiler – Best Overall

This is the fan favorite for a reason. It strikes that balance between “sporty” and “OEM+,” making it perfect for daily drivers or tuned builds.

  • Fitment: ★★★★☆
  • Style: Subtle aggression
  • Material: Real carbon, 2×2 weave
  • Finish: Gloss or matte
  • Install Time: 10–15 mins
  • Price: $130–$180

Why It Works:
On the B8.5 S5’s coupe trunk, the V-style hugs the curves tightly, with a slight kick on both ends for a more dynamic silhouette. It complements stock taillights or aftermarket OLEDs perfectly.

Pros:

  • Matches most builds
  • Lightweight, high-quality weave
  • OEM+ feel without being boring

Cons:

  • Common choice—less “unique”
  • Slight lift at edges if installed cold

2. Ducktail Carbon Fiber Spoiler – Most Track-Look

The ducktail spoiler changes the entire rear profile. Think of it like the RS5’s evil twin—taller, meaner, and made for movement.

  • Fitment: ★★★★☆
  • Style: Tall center lift
  • Material: Pre-preg carbon
  • Finish: Gloss dry or matte
  • Install Time: 15–20 mins
  • Price: $160–$220

Why It Works:
The ducktail’s shape exaggerates the already-wide rear of the coupe. It looks insane from the side and matches carbon diffusers or vented hoods. If you’re running a more track-ready aesthetic, this spoiler’s for you.

Pros:

  • Widens rear appearance
  • Looks custom and premium
  • Great airflow effect

Cons:

  • Can look too bold for stock setups
  • Tall edge can collect dust easily

3. OEM Style Carbon Fiber Spoiler – Cleanest Look

This one’s for the executives. Adds just a whisper of downforce and carbon, no flash. It blends in like it came from Ingolstadt that way.

  • Fitment: ★★★★★
  • Style: Sleek, minimal
  • Material: Carbon fiber (twill weave or forged)
  • Finish: Gloss or matte
  • Install Time: 5–10 mins
  • Price: $90–$140

Why It Works:
It barely lifts off the trunk, but under light it sparkles. Pair it with subtle side skirts or carbon mirror caps, and your S5 becomes a business-class sleeper coupe.

Pros:

  • OEM+ fitment
  • Low-key luxury feel
  • Cheapest real carbon option

Cons:

  • May disappear on black cars
  • Too tame for some builds

4. High Kick Carbon Fiber Spoiler – Wildest Design

This one’s all business in the front, but a party at the back. The arch shoots upward for maximum flair—great for car shows, slammed builds, or RS5-style replicas.

  • Fitment: ★★★☆☆
  • Style: Aggressive arch
  • Material: Glossy wet carbon
  • Finish: High-flare edge
  • Install Time: 20–25 mins
  • Price: $180–$250

Why It Works:
It gives your S5 coupe a seriously mean rear profile. Ideal for those who already have wide wheels, dark taillights, and big exhaust tips. From the rear ¾ view? It looks like it’s doing 120 parked.

Pros:

  • Dominates visually
  • Matches full carbon builds
  • Turns heads without shouting “aftermarket”

Cons:

  • Harder to line up perfectly
  • Doesn’t suit subtle cars

5. Forged Carbon Rear Spoiler – Most Unique Finish

Want a spoiler that looks nothing like what everyone else has? Forged carbon = flake pattern finish that reflects like shattered glass. Exotic and rare.

  • Fitment: ★★★★☆
  • Style: Same as OEM or V-style, different finish
  • Material: Forged carbon
  • Finish: Matte or gloss
  • Install Time: 10–15 mins
  • Price: $170–$230

Why It Works:
It fits the coupe form perfectly but adds an entirely different texture—like it belongs on a Lamborghini Performante or Urus. Looks especially dope with forged carbon engine covers or side mirror caps.

Pros:

  • Very unique appearance
  • Better UV resistance
  • Killer for show builds

Cons:

  • Won’t match traditional twill weave parts
  • Pricier and harder to find

Final Thoughts – Which Spoiler Is Right for You? (~200 words)

The Audi S5 B8.5 has one of the cleanest coupe bodylines Audi ever made. But that’s exactly why the right spoiler makes such a difference—it completes the design. Choosing the perfect rear spoiler depends on your vision. Want something subtle and luxurious? Go with the OEM or forged carbon options. Building a daily driver with visual punch? The V-style gives you the best blend of form and function. Want to stand out and flex on the parking lot? Ducktail and high-kick options go crazy from every angle.

All of these spoilers are easy to install, reversible, and won’t damage your trunk as long as you prep properly. Real carbon fiber also adds resale value and looks premium—not like eBay ABS knockoffs. Just make sure to pair your spoiler with supporting mods: a carbon rear diffuser, black exhaust tips, and maybe smoked tail lights to really tie it together.

At the end of the day, your spoiler isn’t just a piece of carbon—it’s a reflection of your taste. Whether you’re keeping it executive or building a monster, the right rear spoiler makes sure everyone behind you knows you’re not driving a stock S5.
