Porsche 911 991 / 991.2 Prepreg Dry Carbon Fiber GT3 Spoiler (V2)
Engineered for Porsche 911 991/991.2 owners who want a track-DNA rear profile and measurable high-speed downforce, this Prepreg (Dry) Carbon Fiber GT3 Spoiler transforms the engine deck of your 911. Made to factory-spec tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this Porsche 911 carbon GT3 spoiler bolts directly to OEM mounting points, no cutting, no drilling.
The 911 GT3's naturally-aspirated flat-6 character (991.1 GT3: 475 hp / 3.8L NA, 991.2 GT3: 500 hp / 4.0L NA, 991.2 GT3 RS: 520 hp / 4.0L NA) defines the modern track 911, and this spoiler channels that spirit. This V2 version differs in profile from our sister GT3 Spoiler SKU, featuring a more aggressive wing line and lip curl. It serves both 991 GT3 owners as a replacement/upgrade AND 991/991.2 Carrera, GTS, Turbo and Turbo S owners chasing the GT3 look. Autoclave-cured prepreg construction is noticeably lighter than the OEM plastic spoiler.
Key Features
- Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure, homogeneous resin, a more consistent weave.
- GT3-Style Wing Profile (V2): Different from our sister GT3 spoiler SKU, higher angle of attack and more aggressive tip curl.
- Race-Grade Downforce: Optimized profile contributes to rear-axle downforce at speed.
- Lightweight: Noticeably lighter than the OEM plastic spoiler.
- Race-Grade Strength: Carbon fiber offers very high strength for its weight.
- 2x2 Twill Carbon Weave: Authentic pattern under a high-gloss UV-protective clear coat.
- Direct OEM Fit: Plug & play installation on factory 991 / 991.2 engine deck mounting points.
- UV & Chemical Protection: Long-life clear coat against fading, fuel splash, and tar.
Prepreg (Dry) Carbon vs. Wet Carbon: Which Is Better?
Most aftermarket carbon is made using wet lay-up, where resin is applied by hand and cured at room temperature. Prepreg (dry) carbon:
- Cured in an autoclave under high heat and pressure → a more consistent weave
- A controlled resin ratio → lighter and stronger
- The production method widely chosen in motorsport
- Minimal UV fading over years of use
Installation Notes
- Clean the engine deck mounting area thoroughly.
- Dry-fit the spoiler and verify symmetry of the tips.
- Secure with supplied hardware (bolts + 3M VHB tape backing).
- Torque bolts to the manufacturer's recommended torque.
- Avoid washing for 48 hours to allow adhesive cure.
Care & Maintenance
Wash with pH-neutral car shampoo. Apply carbon sealant every 6 months. Keep pressure washer at least 30 cm away.
