ARMASPEED Aero Kits 碳纖維空力套件

Carbon fiber aerodynamic kits for three cars: Toyota GR Yaris, Toyota Supra A90, and Porsche Taycan. I covered the industrial design and the development PM seats, taking each kit from vehicle scan to approved sample.

01 · The Pipeline

Six steps, one pipeline

The pipeline runs from vehicle scan to released product. My seats covered the design and development half: scanning, CAD, first sample review, on-car fitment, and spec/jig sign-off.

03 · First SampleCarbon fiber layup, vacuum bagging, autoclave cure on the first physical part.

04 · Fit RefinementHands-on fitment on the real car. Adjustments until the gap closes.

05 · Spec & JigProduction drawings and the wooden inspection jig used for QC on every unit.

06 · ReleaseFinal product on a customer-spec car, ready for shipping.

02 · Material

Carbon fiber, end to end

Every part is dry-layup carbon fiber: pre-impregnated cloth, vacuum bagged, autoclave cured, then machined and clear-coated. The weave orientation on each part is a design choice, not a default.

03 · Selected Platforms

Three cars from the carbon line

The three kits below are from ARMASPEED’s carbon fiber line. Each one took roughly six to eight months from start to approved sample. The pipeline stayed the same. The donor-car tolerances did not.

04 · Reflection

What the production line sent back

I confirmed each production sample fitted the actual car, set the spec for the logo plate and the surface texture, validated the inspection jigs, and signed off on the hardware spec. Yield issues afterward came back into the next design. The feedback loop was part of the work too.

The three carbon fiber kits above are the highlighted selection. The pipeline shown earlier was first proved out on ARMASPEED’s ABS-material kits, including the Volkswagen Golf 8 GTI that I took from concept through release as the company’s first end-to-end design pilot. Those years later became the foundation for my project management certificates.
