Why Carbon Fiber Rear Spoilers — and What to Look For
A rear spoiler shapes the airflow leaving the car — a ducktail cleans up separation and sharpens the rear end visually, while a GT wing makes real downforce you can feel in fast corners. It is also the part people see first in the rearview mirror.
Look at the mounting base and the underside layup: that is where cheap spoilers crack. Ours use reinforced bases molded to the trunk or hatch contour, with multi-layer UV-stable clear coat as standard.

Customization
What You Can Customize on a Rear Spoiler
Ducktail vs Lip vs GT Wing
OEM+ ducktails, trunk lip spoilers, or adjustable GT wings with aluminum uprights — existing molds cover all three families.
Fixed vs Adjustable
Fixed-angle wings for street looks; swan-neck or upright-adjustable wings for track tuning.
End Plate Options
Carbon end plates in matched weave, with or without logo engraving for private label programs.
Wet vs Dry Carbon
Wet carbon for street builds and value; prepreg dry carbon where weight and stiffness matter.
Weave & Color
2×2 twill, 1×1 plain, forged carbon, Kevlar blends — matched across a full kit order.
Finish
High-gloss or matte/satin clear coat. Gloss shows the weave deepest; matte suits wrapped or stealth cars.
Before You Order
Fitment, Installation & Safety Notes
Installation: ducktails and lip spoilers bond with 3M tape or a tape-plus-screw combo — 15–30 minutes, no drilling on most applications. GT wings bolt through the trunk with backing plates; two people and 45–60 minutes is realistic.
Trunk load: GT wings add real downforce at speed. Use the supplied backing plates and check bolt torque after the first week.
Paint & PPF: clear-coated carbon can be PPF-wrapped like paint. If you plan to paint-match the spoiler, order the matte finish for best adhesion prep.
Not for ducktails and lip spoilers — they bond with automotive 3M tape. GT wings do bolt through the trunk lid; backing plates and hardware are included.
Will the tape hold at highway speed?
Yes — we use genuine 3M VHB tape, the same class OEMs use for badges and trim. Surface prep with isopropyl alcohol is the critical step.
What is the difference between wet and dry carbon spoilers?
Wet carbon is hand-laid and best value for street cars. Dry (prepreg) carbon is autoclave-cured — lighter, stiffer, and the right choice for GT wings and track use.
