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

Engineered for Mercedes-AMG GT 4-Door X290 (2018-2024) owners, this Prepreg Dry Carbon Fiber GT Spoiler is the most aggressive trunk spoiler in our X290 lineup — a motorsport-styled wing profile with pronounced side end-plates for serious downforce character. Manufactured in Europe and quality-controlled by BYC Performance.

Among our three X290 spoiler designs, this GT Spoiler is the most aggressive — distinct from the classic trunk spoiler and the roof spoiler. Built for owners who want a downforce-forward character worthy of the GT 63 S (630 hp) or GT 63 S E PERFORMANCE (831 hp PHEV).

Key Features

• Prepreg Dry Carbon Technology: Autoclave-cured under high heat and pressure, a more consistent weave.
• GT-Style Aggressive Wing Profile: Taller, motorsport-look trunk wing.
• Downforce-Focused: Pronounced end-plates and steeper attack angle vs. the classic trunk spoiler.
• 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

No difference in fitment — same X290 trunk lid geometry.
