Product description
Koshi carbon door sill covers for Alfa Romeo 4C
When the door opens, the sill trim marks the transition into the Alfa Romeo 4C cockpit. Koshi AR4C-033 gives those visible strips a carbon finish. The two elongated pieces follow the sill line; they cover the original sill trim rather than replacing complete structural body sills.
Carbon across the entry area
The manufacturer specifies an overlay construction in 0.6 mm prepreg carbon. The material is cured in an autoclave and coated with a high-gloss clear finish. The emphasis is therefore the exposed weave running along the sill, rather than a new structural component for the vehicle.
Retaining the original trim underneath
The existing OEM sill pieces remain beneath this finish. Compare the long edges and ends of the covers with the entry area on your 4C. This article concerns the trim alongside the door opening; interior door panels, door upholstery and other carbon components are not automatically part of this version.
