BMW tuning specialist Hartge has launched a new assortment of aero add-ons and sport exhaust systems for the 1-Series. Available parts include a front lip spoiler, rear diffuser, side skirts, roof and boot lid spoilers, carbon casings for the exterior mirrors, inserts for the lower air vents, decals and the not so necessary, Hartge emblems. The tuner has also released two new sport exhaust systems with four tailpipes for the 125i and 135i models with the M Aerodynamic package.
