Mercedes-AMG GT 63 X290 4-Door (2018-2024) Prepreg Dry Carbon Fiber Roof Spoiler
Engineered for Mercedes-AMG GT 4-Door X290 (2018-2024) owners, this Prepreg Dry Carbon Fiber Roof Spoiler is an aero accent installed at the rear edge of the fastback roof. Imported from leading manufacturers around the world and quality-controlled by BYC Performance, this roof spoiler bonds directly to the OEM rear roof edge.
Of our three X290 spoiler designs, this is the only one mounted on the roof (not the trunk). Trunk versions are offered as the classic Spoiler and the GT Spoiler. All three can be combined or chosen individually.
Key Features
- Prepreg Dry Carbon Technology: Autoclave-cured under high heat and pressure, a more consistent weave.
- Rear Roof Edge Position: Distinct from trunk spoilers, extends the fastback silhouette and manages airflow.
- Aero Flow Management: Conditions airflow onto the rear glass at high speed.
- 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) rear roof edge.
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
Installation Notes
- Clean and dry the rear roof edge with isopropyl alcohol.
- Test-fit the roof spoiler; ensure no contact with the rear glass.
- Peel 3M protective film progressively, press the spoiler onto the roof edge.
- Apply firm pressure for 5-10 minutes.
- Avoid car washes for 24 hours.
Care & Maintenance
Wash with pH-neutral car shampoo. Apply carbon-safe sealant every 6 months. Keep pressure-washer nozzle 30 cm from tape edges.
FAQ
Fits C190 GT sports car?
No.
Difference from the trunk spoilers?
The Roof Spoiler mounts on the rear roof edge, not the trunk. Trunk versions are the classic Spoiler and the GT Spoiler. Three distinct positions; can be stacked.
GT 53 / 63 / 63 S?
Same X290 roof edge geometry across trims.
Can the roof spoiler and a trunk spoiler be combined?
Yes. They complement each other aerodynamically: roof spoiler manages flow onto the rear glass while a trunk spoiler delivers downforce.
Will it come off at high speed?
No. 3M VHB tape with proper prep is highway-rated.
Can it be painted?
Yes, but carbon weave will be hidden.
Shipping?
