Edison Hwang 2011 Vorsteiner GTRS-3 Build Check out the latest on the Los Customs GTRS-3 Build Los Customs in Gaithersburg, MD is building Edison Hwang’s incredible 2011 M3 with the Vorsteiner GTRS-3 body kit. Only 100 of these kits were ever produced so this serially numbered vehicle will truly be a rare bird. Edison has some incredible plans in store for this beast which should be pushing out as much power as a typical super-car and will be similarly equipped with a BBK, racing interior, and other goodies. Look for this monster to debut at Carlisle Performance & Style. Carlos Blanco, automotive artist and craftsman will be on site to answer any questions and discuss modification options for your vehicle.
