While not many in numbers, Wald International believes that some owners of the Rolls Royce Phantom Drophead Coupe would like to give the luxurious convertible a more bespoke tuner look.

The Japanese firm's offering is a styling package is named "Black Bison Edition", which starts off with an assortment of aero parts made of carbon fiber.

The latest model to receive Wald International's dark "Black Bison" treatment is the Porsche Panamera sports saloon. As usual, the Japanese tuning firm's package is centered on a raft of styling parts with minimal performance upgrades.

The Panamera's exterior receives a comprehensive makeover with a new carbon fiber aero kit that adds a new front bumper with sculpted air vents, rear wheel arch extensions, front fender mesh vents, rocker panels, a deck lid spoiler and a redesigned rear bumper with extra vents and a diffuser.

Japanese tuning firm Wald International likes to give its customers' rides a sinister look and its take on the new 2012 Mercedes-Benz CLS 63 AMG is no exception.

Even though in stock form the AMG version of Mercedes-Benz's sports saloon comes with its own aero-aids, Wald International has prepared a new and more aggressive styling package named Black Bison.

The Japanese domestic market [JDM] Nissan Skyline, which the rest of the world knows as the Infiniti G37 sedan, is the latest car to capture the attention of Wald International.

The renowned Takatsuki-based tuning firm has presented a Sports Line Black Bison Edition package for the saloon model consisting almost entirely of cosmetic upgrades.
