Mercedes-AMG GT 63 X290 4-Door (2018-2024) Prepreg Dry Carbon Fiber Spoiler

Engineered for Mercedes-AMG GT 4-Door X290 (2018-2024) owners, this Prepreg Dry Carbon Fiber Spoiler is the classic low-profile trunk spoiler — elegant downforce and visual enhancement. Manufactured in Europe and quality-controlled by BYC Performance, this spoiler bonds directly to the OEM trunk lid.

Of our three X290 spoiler designs, this classic spoiler is the most balanced choice for daily use. For more aggressive GT-style trunk wings, see the GT Spoiler; for the rear roof edge, see the Roof Spoiler. This classic spoiler accentuates the AMG ducktail line in carbon.

Key Features

• Prepreg Dry Carbon Technology: Autoclave-cured under high heat and pressure, a more consistent weave.
• Classic Low Profile: Elegant ducktail character; ideal for daily driving.
• Visual Enhancement: Brings the AMG ducktail line out in carbon weave.
• 2x2 Twill Carbon Weave: Authentic pattern under UV-protective clear coat.
• 3M VHB Tape Mounting: Pre-applied automotive-grade tape.
• UV & Chemical Protection: Long-life clear coat.
• Direct OEM Fit: X290 (2018-2024) trunk lid upper surface.

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

Most aftermarket carbon parts use wet lay-up. Prepreg (dry) carbon:

• Autoclave-cured → a more consistent weave
• A controlled resin ratio → lighter, stronger
• The production method widely chosen in motorsport
• Minimal UV fading
