Porsche 911 (991 / 991.2) | Prepreg Dry Carbon Fiber GT3 Spoiler

Porsche 911 (991 / 991.2, 2012-2019) Prepreg Dry Carbon Fiber GT3 Spoiler

Engineered for Porsche 911 991 / 991.2 Coupé owners, this Prepreg Dry Carbon Fiber GT3 Spoiler is a motorsport-grade fixed rear wing inspired directly by the 911 GT3 991.1 and 991.2 factory wing. Quality-controlled by BYC Performance, this Porsche 911 GT3 carbon spoiler bolts directly to OEM 911 GT3 mounting points, and can also be installed on Carrera and Turbo Coupé bodies as a visual upgrade.

On the 911 GT3 991.1 (3.8L NA 475 hp) and 991.2 (4.0L NA 500 hp), the fixed rear wing is a core aero feature. This carbon spoiler serves two purposes: (1) direct carbon replacement for 991 GT3 owners and (2) a GT3-look visual upgrade for 991 / 991.2 Carrera, Carrera S, GTS, and Turbo Coupé owners who prefer a fixed GT3-style wing over the OEM active rear spoiler. Autoclave-cured dry carbon offers very high strength for its weight.

Key Features

• Prepreg Dry Carbon Technology: Autoclave cure under high heat and pressure; a more consistent weave.
• Dual Positioning: 991 GT3 OEM wing equivalent AND GT3 visual upgrade for Carrera / Turbo.
• Race DNA: Patterned on the 991 GT3 (475-500 hp 4.0L flat-6 NA) factory wing.
• Direct GT3 Fit: Plug & play with 991 / 991.2 GT3 wing stand mounts.
• Adapter Needed for Carrera / Turbo: Active spoiler models require an adapter / mounting plate (sold separately); active spoiler function is lost.
• 2x2 Twill Carbon Weave: Deep carbon pattern under a high-gloss UV-protective clear coat.
• Lightweight: Lighter than the OEM painted GT3 wing thanks to full carbon construction.
• Aerodynamic Downforce: Significantly reduces rear-axle lift at speed.

Prepreg Dry Carbon vs. Wet Carbon: Which Is Better?

Most aftermarket carbon parts are made using wet lay-up, with hand-applied resin cured at room temperature. Prepreg dry carbon:

• Cured in an autoclave under high heat and pressure → a more consistent weave
• Controlled resin ratio → noticeably lighter
• The production method widely chosen in motorsport
• Minimal UV fading over years of use

Installation Notes

1. Remove the OEM GT3 wing or OEM active rear spoiler (Carrera/Turbo); disconnect the active-spoiler electronics if applicable.
2. Position the carbon GT3 spoiler on the wing stand mounts; use the adapter for Carrera / Turbo.
3. Torque bolts to the manufacturer's recommended torque.
4. Verify panel alignment and wing angle.
5. Professional installation strongly recommended.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer 30 cm away. Bi-annual torque check on wing stands recommended.

FAQ

Does this fit the 992 (2020+)?
No. 992 rear lid and wing geometry is different.

Does this fit the 997?
No. The 997 is the previous generation.

How does it mount on a standard Carrera?
The OEM active rear spoiler is removed and an adapter / mounting plate is used for the GT3 spoiler stands. Active spoiler function is lost. Contact BYC for options before ordering.

Does it fit GT3 RS or GT2 RS?
No. GT3 RS and GT2 RS use swan-neck wing geometry.

Does it fit Cabriolet or Targa?
Not recommended. Cabriolet and Targa rear lid / top mechanisms are different.

Is losing the active spoiler a problem?
The fixed GT3 wing produces far more downforce than the active spoiler at speed, though low-speed urban aero changes.

Shipping time?
In-stock items ship in 1-3 business days. Shipped via partner couriers for the oversized wing. Parts sourced to order are delivered within 30 days of the order date at the latest.
