Porsche Cayenne | Prepreg Dry Carbon Fiber Door Trim

Porsche Cayenne (2018+) Prepreg Dry Carbon Fiber Door Trim

Engineered for Porsche Cayenne 9YA (E3 / PO536, 2018+) owners, this Prepreg Dry Carbon Fiber Door Trim set adds a motorsport-inspired carbon accent to your luxury SUV's side profile while protecting the door paint from stone chips. Imported from leading manufacturers around the world and quality-controlled by BYC Performance, this Porsche Cayenne carbon door trim bolts to OEM side door lines: no cutting, no drilling.

If you're building a Porsche Cayenne tuning project and want to reinforce the side profile and tie together your carbon side skirt and fender flare for a cohesive aesthetic, this dry carbon door trim set is built for you. Autoclave-cured prepreg carbon offers a worthwhile weight saving over OEM plastic, is UV-fade resistant, and long-lasting. The aggressive carbon presence echoes the 4.0L V8 biturbo Turbo GT Coupé (631 hp) sport aesthetic across both 9YA SUV and Coupé bodies.

• Paint Protection: Shields door paint from stones, tar, and road chemicals thrown by the tires.
• Lightweight: A worthwhile weight saving over OEM plastic or painted panels.
• 2x2 Twill Carbon Weave: Authentic carbon pattern under high-gloss UV-protective clear coat.
• Direct OEM Fit: Plug-and-play on Cayenne 9YA SUV and Coupé side door lines using 3M VHB tape and clips.
• UV & Chemical Protection: Clear coat resists fading, cracking, and road chemicals.

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

Most aftermarket carbon is wet lay-up with hand-applied resin cured at room temperature, leaving 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
