Alfa Romeo 4C Carbon Fiber exterior Bottom window frame

Product description

Koshi carbon lower window trim covers Alfa Romeo 4C

The lower side-window edge forms a visible line along the Alfa Romeo 4C doors. These Koshi carbon covers follow the lower exterior window trims and carry the carbon detail along that line. Their elongated shapes include the curves and ends of the illustrated window finishing parts.

Trim on the outside of the door

These are covers for the original window trims. They do not replace the glass or window mechanism, and they are not new rubber seals. The manufacturer describes them as additional covers over the originals with a thickness of 0.6 mm.

Carbon along the window opening

Koshi uses autoclave-cured prepreg carbon with gloss clear coat. Check the meeting points at both ends of each existing trim and assess the space beside the moving glass before attachment. For this application, matching the shaped exterior trim matters more than treating the parts as universal carbon strips to cut to size.
