The tuners from JFactory have released this stunning body kit and performance package to completely transform the new BMW Z4. This particular model pictured was built to participate in the Fuji Speedway 7 hour endurance race series in Japan. The JFactory BMW Z4 features an aero kit consisting of a new front bumper, front splitter add-on, side skirts, and rear bumper. A full carbon fiber vented hood allows cooler air into the engine bay, and it was much needed for the performance parts found underneath.
The tuning company installed a complete supercharged system from Dixis Redhot to increase performance on the track. All the new power is transferred to extremely lightweight BBS RE-Mg 19-inch wheels made from strong and lightweight magnesium. To participate at the Fuji Speedway, a new suspension setup was required which lowers the BMW Z4. Topping it off is a huge GT-style carbon fiber rear wing that was custom designed by Varis for this model.[Source: carsroute]
