Kelleners Sport tunes the BMW Z4 E89

Taking the Roadster to a new level of style and performance.

There are two versions of the BMW Z4 sDrive35: the sDrive35i and the sDrive35is, the latter of which makes 35 horsepower and 32 lb-ft. of torque more. While no M model has been introduced by BMW, Kelleners Sport has introduced a Z4 tuning program that is the next best thing.

The turbocharged inline-six engine that powers the rear wheels of the Z4 E89 gets a significant boost in power. Thanks to an ECU tune, the 335 horsepower engine has been pushed to 400 ponies and 398 lb-ft. (539 Nm) of torque.

The ride and handling have also been improved with an upgraded suspension and new wheel choices. Kelleners Sport has installed new sport springs that lower the ride height by 20 mm at the front and 10 mm at the rear, thus improving the overall center of gravity while preserving ride comfort. Two different wheels are available, each with three optional finishes. Customers can choose either the “Hamburg” or “Berlin” wheel designs in 19- or 20- inch diameters and widths ranging from 8.5/9.5 inches to 9/10 inches.

Kelleners Sport has given the interior a bit of luxury and athleticism. A new three-spoke steering wheel faces the driver and offers greater control over the stock unit. The pedals and footrest have been replaced with new aluminum equipment, while the floor mats are now made of velour. Customers can also choose to install new carbon fiber trim, finished wood, and fine leather from the Kelleners Sport saddlery department.

The Kelleners Sport BMW Z4 E89 tuning program is currently available as a complete package or individual accessories. Kelleners Sport can also custom tailor the interior to customer specification.
