Porsche 718 Cayman / Boxster (982) | Prepreg Dry Carbon Fiber Spoiler

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

Engineered for Porsche 718 Cayman (982 chassis, 2016+) owners, this Prepreg Dry Carbon Fiber Spoiler gives your mid-engine coupe a motorsport-inspired rear silhouette while improving aerodynamic balance at speed. Made to factory-spec tolerances by leading manufacturers around the world and quality-controlled by BYC Performance, this Porsche 718 carbon spoiler bonds to the OEM rear deck via 3M double-sided tape and supplied hardware - no cutting required.

If you are building a serious Porsche 718 tuning project and want race-grade visuals plus functional rear downforce, this dry carbon spoiler is built for you. Autoclave-cured prepreg carbon is noticeably lighter than wet-lay carbon parts, superior in structural integrity, and excellent in long-term UV resistance. It complements the 982 Cayman flat-4 turbo (300/350/365 hp) and flat-6 NA 4.0L GTS (400 hp) drivetrain options, making it an ideal aesthetic and functional upgrade for both track and street.

Key Features

• Prepreg (Dry) Carbon Technology: Autoclave-cured under high heat and pressure; homogeneous resin distribution, a more consistent weave.
• Motorsport-Inspired Profile: Down-curved trailing edge adds rear-axle downforce at speed.
• Weight Reduction: Noticeably lighter than the factory trim.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under a high-gloss UV-protective clear coat.
• OEM Fit: Plug and play installation on the 982 Cayman rear deck. Secured with 3M double-sided tape and supplied hardware.
• UV and Chemical Protection: Long-life clear coat protects against fading, cracking, and exhaust heat.
• Race-Grade Strength: Carbon fiber offers very high strength for its weight; resistant to highway-speed vibration.

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

Most aftermarket carbon parts are made using wet lay-up, where resin is applied by hand and cured at room temperature - leaving air voids and inconsistent weight. 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

Installing the Porsche 718 carbon spoiler uses adhesive and supplied hardware. Professional installation is recommended:

1. Clean the rear deck surface with isopropyl alcohol.
2. Test-fit the spoiler base; do not remove the adhesive backing yet.
3. Mark alignment, then press 3M double-sided tape firmly into place.
4. If supplied bolts are included, torque from the trunk inner surface to the manufacturer's recommended torque.
5. Do not wash for 24 hours so the adhesive can reach full strength.

Care and 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

Compatible with the Boxster?
Generally no. The 718 Boxster folding soft-top and integrated factory spoiler design are not suitable for this style of aftermarket rear wing. Primary target is the 718 Cayman coupe.

Does this fit the 981?
No. The 981 (2013-2016) and 982 (2016+) have different deck/trunk geometry.

Does this fit the GT4 RS?
No. The Cayman GT4 RS (2022+) ships with a factory swan-neck wing.

Does this fit the Spyder or GT4?
The GT4 and Spyder come with factory active/fixed wings; this product is not designed as an add-on or replacement for those.

Will rain damage dry carbon parts?
No. Autoclave-cured prepreg carbon is fully waterproof and weather-resistant.
