While BMW is currently designing the next generation Z4, Japanese tuner Rowen gave updating the current generation a try. We don’t necessarily think it needs updating, but to each his own.
The updates for the BMW Z4 began with the exterior where the base element was carbon fiber. The kit consists of a new front bumper spoiler, side steps, a side carbon under flap, rear bumper spoiler, and wing all made of carbon fiber. A new set of wheels complete the look, while the rear of the vehicle gets a new titanium high performance exhaust system that weighs 28 lbs less than the standard exhaust. However, Rowen has yet to reveal if this new exhaust system will translate into any changes under the hood, but it is very possible.[...]
