Crowd-sourced? What is crowd-sourced? Well, Nissan has a facebook page, where fans are able to choose the powertrain, turbo kit, exhaust, suspension and brake setup for their Z track car. Fans are able to vote what they want to see on the 370Z and Nissan will do just that. How cool is that! Check out the videos for stage 1 and stage 2 after the jump.
