Here’s a rare find. A BMW Z4 E89 radically transformed by the Japan-based Rowen house. In a few words: extensive use of carbon fiber materials, big wheels and … LEDs.
A new front apron with splitter sits at the front (there are also the LEDs), the side skirts have been redesigned and the tips of the exhaust pipes are all titanium. If that carbon wing at the back was a tad bigger, the Z4 would be pretty reminiscent of a full-blown GT car.
We cannot omit stating the obvious that the wheels are new and the suspension has been lowered. When it comes to a price, the Rowen Z4 White Wolf RR is staged so you’ll end up somewhere in between the 493,500 Yen to 756,000 Yen range. That is $6,200-$9,500.
Do we need to remind you that, at it’s best the E89 has a twin-turbocharged, 3.0-liter straight six. That’s 340 PS and 450 Nm of torque, crunched by a 7-speed dual clutch automatic gearbox and good for a 4.8 second run to the 62nd mile an hour landmark.

It is a regularly recurring process: if a car manufacturer presents a new model, its predecessor generation often seems outdated and old-fashioned all of a sudden, even though there was no reason for complaint previously. This happens at a time when the model usually has already gone through more or less intense model care. Although this kind of “spontaneous aging” is rather below average for the first-generation-BMW Z4, JM Cardesign from Bergheim performed a very special kind of face-lifting on the E85-Roadster presented here. The tuner fitted the “old” Z4 with the front pieces of the new E89 model. The front bumper and grille were modified in extensive handiwork to match the headlights, mudguards and bonnet of the E85. The result is very harmonious: even MBMW enthusiasts will take a moment to entirely identify the cross-generation transformation. JM Car Design also applied some classic craftsmanship in the area of the rear wheel runs.
