This is Duke Dynamics new styling and wheel program for the most recent iteration of the BMW Z4 roadster (internal codename E89).

The Japanese tuner's goods are highlighted by a wide body kit that adds a few inches to the hardtop models wheel arches on all four corners, thus making space for the use of bigger 20-inch wheels shod in uber beefy rubber - you know, of the kind that will make you a star client at your local tire shop.

Completing the look is a new vented hood and redesigned wider bumpers, the front with an optionally available carbon fiber lip spoiler, and the rear with a carbon fiber diffuser and quad exhaust pipes.

According to Worldcarfans, the basic aero package is listed for $10,400 or about €7,600 at today's exchange rates.
