Spirit of Le Mans (SOLM) "Racing" tartan fabric is reminiscent of the most famous motorsport livery colors in history; the iconic Gulf racing of the late 1960's. Ford GT40, Porsche 917, McLaren M20 Can-Am, McLaren F1 GTR, Aston Martin Vantage, and Audi R8 all wore this beautifully simple color combination. SOLM plaid is unbacked.
