Audi R8 4S Carbon Fiber Rear Wing

Dry Carbon Fiber · Through-Bolt · Track-Tested
Real dry carbon fiber rear wing — track-spec downforce.
The 2015-2025 runs handsomely from the factory but the corresponding trim panel is conservative. RW Carbon’s Rear Wing replaces or extends that area with genuine hand-laid dry carbon fiber, sharpening the visual aggression without changing the underlying body. Built and quality-controlled in RW’s Anaheim, California facility.
Built in Anaheim, California from real dry carbon fiber, then UV clear-coated for high-gloss shine and weather protection. Install: Through-Bolt to Trunk Lid — 30-45 minute job. Reversible: No — drilling required.
What Makes RW’s Rear Wing Different
Genuine Dry Carbon Fiber
Hand-laid dry carbon fabric with the perfect resin blend — rigid, lightweight, and the deep weave you can’t fake with hydrodip or wrap.
UV Clear-Coat Protection
Every spoiler gets a final clear coat for high-gloss shine and protection against UV yellowing, road salt, and weather. Stays new-looking through years of daily driving.
3M Tape Adhesive Install
No drilling, no bodywork, no clips. Pre-cut RW spoiler bonds directly to the factory trunk lid via 3M VHB tape — a 10-15 minute job with basic tools.
Performance Style Profile
The lip silhouette mirrors the factory M Performance accessory spoiler at a fraction of the cost — classic BMW M-styling without M Performance pricing.
Hand-Built in Anaheim, CA
Every F80 spoiler is hand-laid and quality-controlled in RW Carbon’s Southern California facility before it leaves the warehouse. No overseas drop-ship.
100% Reversible
The 3M tape lifts cleanly with heat — if you ever want to revert to OEM (lease return, resale, restoration), the factory trunk lid is untouched.
Inside The Build
30-45 Minute Through-Bolt Install
Tape-on adhesive install — preserves all factory surfaces:
- 3M VHB tape adhesive — bonds directly to factory paint, no clips or fasteners
- No drilling — trunk lid is not modified, no body work required
- 10-15 minute job — clean surface, peel backing, press into position
- Reversible — tape lifts cleanly with heat if you ever revert to OEM
- Tools needed — isopropyl alcohol wipe, masking tape for alignment, pressure
- Cure time — 24 hours undisturbed before driving in rain or washing
- No tuning required — cosmetic part, no ECU work
- Surface temp — install above 60°F for best 3M adhesion
Ceramic-coated cars: The trunk lid attachment area must be polished or buffed to remove the ceramic layer before install — 3M VHB and primer don’t bond reliably to ceramic-coated paint. Standard sealants and waxes are fine.

FAQ
Will it fit my F30 335i / 340i?
No — this spoiler is shaped specifically to the F80 M3’s factory trunk lid. RW Carbon offers separate F30 trunk spoilers for non-M3 chassis. The F80 M3 trunk lid contour is M-specific.
Should I order the Trunk Spoiler Only or the +3M Tape kit?
Order the +3M Tape and Promoter kit ($20) unless you already have automotive-grade 3M VHB tape and surface primer on hand. The kit ships pre-cut for the F80 spoiler footprint — saves time and ensures correct adhesion.
Is this real carbon fiber or hydrodip / wrap?
Real dry carbon fiber. Hand-laid carbon fabric with rigid resin blend, then clear-coated. You can see and feel the genuine weave — this is not a printed plastic part with a carbon-look finish.
Will it remove cleanly if I sell the car or go back to stock?
Yes. 3M VHB tape lifts cleanly with moderate heat (heat gun or hair dryer) and patient peeling. Any residue cleans off with adhesive remover — the factory trunk lid paint underneath is untouched.
What if my car is ceramic coated?
The trunk lid attachment area must be polished or buffed to remove ceramic before install. 3M VHB doesn’t bond reliably to ceramic-coated paint. The rest of the car’s ceramic stays intact — only the spoiler footprint needs prep.
Can I drive immediately after install?
Yes for normal driving. RW recommends 24 hours undisturbed before driving in heavy rain or running through a car wash — gives the 3M VHB full cure time.
