Product Details
A carbon fiber spoiler generates real downforce at speed — a few millimeters off on the airfoil profile and the aero benefit is gone. We mold every spoiler from a precision-machined die, not hand-layup over foam. Consistent shape, consistent performance, every piece.
Precision-Molded Airfoil, Not Hand-Laid
Pre-preg compression molding with CNC-machined dies gives every spoiler the exact profile your designer specified. The layup is tailored: UD layers on the high-stress bottom skin, 3K twill on the visible top surface. After curing at 130°C under pressure, each wing is inspected for surface defects and dimensional accuracy.
From Concept Sketch to Full Production
Send STEP/STP/IGS and we quote tooling + piece price upfront — no hidden fees. Only have a sketch? Our engineers develop the 3D model. Physical sample? We reverse-engineer it. Lip spoiler to GT wing, 10-piece prototype to 10,000-piece production — one factory, one QC system.

Applications
- Aftermarket Spoiler Kits — Lip spoilers, ducktails, and GT wings for popular models. Direct bolt-on with OEM mounting points or universal fit with supplied brackets.
- Track & Race Cars — Adjustable GT wings generating real downforce. Multi-position mounting for different track configurations. Light enough to not upset rear weight distribution.
- Tuning Brand Custom Lines — Aftermarket brands ordering exclusive spoiler designs with custom profiles, endplate logos, and proprietary weave patterns. We sign NDAs.
- Supercar & Hypercar OEM — Low-volume, high-spec active spoiler components for boutique manufacturers. T700 grade, autoclave-cured options available.
- Motorcycle Rear Spoilers — Smaller-scale aero parts for sportbikes. Same compression molding process, smaller mold, faster turnaround.
Why Choose YTCarbon
- Proven at the 2025 World UAV Expo — Our compression-molded parts drew automotive and industrial buyers who needed complex shapes. Spoilers are where that capability really shines.
- Functional Aero, Not Just Looks — Molded from precision dies, not hand-laid over foam. Same shape, same downforce, every unit — piece one to piece one thousand.
- Hybrid Layup for Strength + Aesthetics — 3K twill visible surface, UD structural layers underneath. Look on the outside, strength where it matters.
- Multi-Part Mold Capability — GT wing = upper skin + lower skin + endplates + internal ribs. All molds designed as a matched set so every component fits perfectly.
- From Sketch to Production — No 3D model? We develop CAD from sketches or photos, optimize for moldability, preserve aero intent. Full design-through-production under one roof.
Certifications
Every custom molded carbon fiber spoiler from YTCarbon is produced under ISO 9001:2015 quality management. RoHS and CE compliant. Mold inspection reports, first article dimensional checks, and flexural testing on sample pieces are standard. Our Shenzhen factory maintains full traceability from raw fiber lot to finished spoiler.
How We Manufacture Your Carbon Fiber Spoiler
Spoiler manufacturing starts with your 3D design in STEP, STP, or IGS format. Our engineers analyze the profile and split it into mold sections — typically upper skin, lower skin, and endplates for a GT wing, or a single upper/lower mold pair for a lip spoiler. Draft angles and parting lines are designed to allow clean demolding without damaging the airfoil surface. The molds are CNC machined from aluminum (prototyping) or P20/718 steel (production), then polished to the target finish. Pre-preg layup is where spoilers differ from simpler parts: we place 3K twill pre-preg on the visible surfaces and UD pre-preg in the structural zones — typically the bottom skin near the mounting points and along the span. The layup goes into the mold, the press closes, and the part cures at 130°C under 5–10 MPa. After demolding, we trim flash, drill mounting holes, sand edges, and assemble the wing (bonding upper and lower skins, attaching endplates). Every finished spoiler is checked against the 3D model for profile accuracy and surface quality before shipping.
