U.S. tuner Vorsteiner has developed a customization plan for the latest BMW M5 (F90). The centerpiece of the tuning is a body kit called GTS Carbon.
Up front, the car gets a neat spoiler lip, while the rest remains stock. The rear end appears considerably more style-conscious, with a small faux diffuser in the middle which has four fins instead of three and a nice ducktail on the trunk lid. Everything comes made from carbon fiber and tested for aerodynamic performance (complete with the certificates).
Aside from the kit, the show car boasts a set of in-house-designed V-FF 103 wheels painted grey and a sports-grade exhaust system.
