Product description
Koshi Maserati GranTurismo carbon audio button trim MSR-11
The slim Koshi MSR-11 strip surrounds four round audio controls in the Maserati GranTurismo. The panel tapers at one end and has four openings in a row. Carbon therefore sits directly around the buttons without replacing the larger screen frame. Its elongated shape makes it a focused detail for the existing audio controls rather than a complete audio-system trim conversion.
Material and specification
The prepreg carbon is autoclave-cured at 140°C and 6 bar, with a stated 0.6 mm thickness and gloss finish. Choices are carbon, white, yellow, orange, red, blue, Italian flag v1 and Italian flag v2. The two flag designs remain separate options.
Installation and application
MSR-11 corresponds to the pictured GranTurismo four-button layout. The original panel remains under the cover. Buttons, electronics and the wider screen frame are separate from this individual trim piece.
