Porsche 718 Cayman (982) | Prepreg Dry Carbon Fiber Swan Neck Spoiler

Porsche 718 Cayman (982, 2016+) Prepreg Dry Carbon Fiber Swan Neck Spoiler

Engineered for Porsche 718 Cayman (982 chassis, 2016+) owners, this Prepreg (Dry) Carbon Fiber Swan Neck Spoiler brings the top-mount wing geometry borrowed directly from GT3 and GT4 RS motorsport cars to street and track use. Made to OEM-grade tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this Porsche 718 carbon swan neck spoiler ships complete with swan-neck uprights and a full-carbon wing profile mounted on the Cayman's rear deck.

The swan neck mounting system keeps the high-pressure flow on top of the wing unobstructed by uprights, generating more downforce at the same angle of attack. Porsche applies the same solution on the GT3 R, 991 GT3 Cup and 718 Cayman GT4 RS. The 982 Cayman's fixed coupé rear deck provides a natural mounting base for this high-mount wing, which is why this product is engineered Cayman-only. Autoclave-cured prepreg carbon is noticeably lighter than wet-lay carbon, offers very high strength for its weight and is UV-resistant.

Key Features

• Swan Neck Top Mount: Clean underside airflow; more downforce per degree of attack.
• Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure; a more consistent weave.
• Full Carbon Uprights + Wing: Both uprights and profile are full prepreg carbon.
• Motorsport-Inspired: GT3 / GT4 RS race aero philosophy.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under high-gloss UV-protective clear coat.
• OEM Mounting: Bolts to the Cayman rear deck; mounting plates included.
• UV & Chemical Protection: Resists fading, cracking and wash chemicals.

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

Most aftermarket carbon parts are made using wet lay-up, with hand-applied resin. Prepreg (dry) carbon:

• Autoclave-cured 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

1. Clean the rear deck / trunk lid surface with isopropyl alcohol.
2. Use the template to mark upright drill points.
3. Drill the specified hole size and apply seam sealant.
4. Bolt the swan-neck uprights to the rear deck.
5. Mount the wing profile to the uprights; tighten hex bolts in sequence.
6. Tighten upright bolts to the manufacturer's recommended torque.
7. Professional installation strongly recommended.

Care & Maintenance

Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure washer nozzle at least 30 cm from surface.

FAQ

Does this fit the 981?
No. The 981 has different rear deck geometry.

Compatible with the Boxster?
No. The Boxster's folding soft-top rear deck cannot accept a high-mount swan-neck wing. This product is Cayman-only.

Compatible with the GT4 RS?
The GT4 RS already ships with a factory swan-neck wing; this part is an upgrade for non-RS Caymans. Verify fitment before ordering.

Does installation require drilling?
Yes. The swan-neck uprights bolt through the rear deck panel and require drilling with seam sealant.

Can the trunk still open?
Yes. The wing's high mount does not obstruct the trunk lid opening clearance.
