Product description
Koshi carbon door triangle covers for Alfa Romeo 4C
These two slender triangles bring carbon to the exterior door panels of the Alfa Romeo 4C. The tapering surfaces of Koshi AR4C-026 follow the illustrated triangular outline and keep the accent localised. They cover existing pieces rather than replacing the complete interior door trim.
Overlay rather than replacement panel
Koshi specifies a 0.6 mm OEM cover for AR4C-026. That distinction matters: the underlying triangle panel remains on the car and is covered. A differently shaped carbon triangle with its own attachment clips is another article and should not be selected merely because its name sounds similar.
Visible weave with a gloss finish
The manufacturer uses prepreg carbon cured in an autoclave and finished in high gloss. The pattern remains visible across the long narrow surfaces. Match the point, base and long edges against the original panels to assess this cover’s specific contour before it is permanently attached.
