Product description
Koshi carbon steering trim Audi RS3 RS4 2017-2018
Koshi AUD-023 joins the left and right button areas of the Audi RS3 and RS4 2017–2018 wheel with a carbon centre arc. Two rectangular open frames connect to the circular contour. The lower centre arc ends in two separate tips.
Open underside of the centre frame
This outline distinguishes the trim from a fully closed circle. Horizontal frames leave the buttons visible in their existing positions and add carbon borders to the spoke surfaces. The lower central spoke remains a separate area; this component follows the pictured button frames and centre arc.
Carbon overlay on OEM trim
Koshi describes AUD-023 as a cover on the original OEM part. The manufacturer uses 0.6 mm prepreg carbon cured in an autoclave and coated with high-gloss clear lacquer. RS3/RS4 2017–2018 identifies this particular wheel layout. Weave runs across the narrow surrounds and circular centre edge.
