Kelleners Sport offers performance kits for all diesel and petrol engines available for the European specification 3-Series.
As an example, the tuner tells us that the diesel-powered 320d is boosted from 181hp (184PS) and 380Nm (280 lb-ft) to 215hp (218PS) and 435 Nm (321 lb-ft), while the 2.0-liter turbocharged petrol engine of the 328i rises from 241hp (245PS) and 350Nm (258 lb-ft) to 290hp (294PS) and 420 Nm (310 lb-ft) respectively.
Among the additional hardware upgrades are a sports exhaust system with new tailpipes, and a sports spring set that lowers the car’s ride height by 30mm (1.2 inches) or a tauter coilover suspension that drops the height by 60mm (2.4 inches and promises to improve handling.
The German tuner offers an aero body kit for both the regular and M Sports Package-equipped version of the F30 that includes a front spoiler lip, a rear skirt extension and a trunk spoiler. A choice of 19- or 20-inch light alloy wheels completes the look.
As for the interior, customers can opt for a full leather treatment in a choice of more than 60 different colours, while other upgrades include carbon and/or wood inlays, aluminium pedals and velour floor mats.
