Japanese tuner 3DDesign has revealed a styling program for both the Coupe and Convertible variants of the all-new BMW 4 Series. On the outside, changes are limited to a front lip spoiler, an optional carbon-fiber reinforced plastic front splitter, a roof spoiler, trunk-mounted spoiler, and CFRP rear diffuser. A selection of 20-inch alloys rounds off the exterior treatment. Modest interior upgrades include alloy pedals, an aluminum hand brake lever and auxillary gauges.
