The BMW Z4 GT3 is a fixed-roof, race-ready version of the standard Z4. Instead of a straight six, the Z4 GT3 is powered by a 480-horsepower 4.0-liter V8 coupled to a six-speed sequential gearbox. Designed and engineered for the track, this Z4 definitely means business – just look at it. You can purchase your own version for around $400,000, and after paying that price, you can have your new track assassin shipped to you... in pieces.
BMW ships the car out in boxes and it's up to the proud new owner to put it together. Recently, Swedish race crew, Team West Coast Racing, did just that. The entire build took them 600 hours and they kept a camera rolling during that period. A time-lapse video captures the action as bare chassis becomes complete racer. 600 hours is 25 days, and 25 days is a long time to wait in between track sessions. In this case, the wait seems worth it and you can see the build video for yourself after the jump.
