While dressed in Black Sapphire Metallic body panels, the uber road-hugging M5 has been fitted with ADV.1's flagship ADV15R Track Spec CS directional wheels measuring 21x9.5-inch (front) and 21x11-inch (rear).
The three-piece lightweight 6061 T6 treated forged aluminium wheels feature a Matte Bronze finish for the wheel front and a Glossed Brushed Manbronze finish for the lips, and have undergone in-house machining, engineering and mill-programming.
Available wheel sizes start from 18 to 22-inch diameters and from 4.5 to 15.5+ inches in width.
