Fast and Furious 4 Cars - Tuned 4 Fury!

The cars off to race. True race cars.

Dominic "Dom" Torretto's 1970 Dodge Charger

Subaru Impreza WRX STi

1970 Turbocharged Dodge Charger

1998 Nissan Skyline ER34

Well, I'd say that these cars are tuned for performance only, and the extreme body modification trend is declining back to the true blood of street racing.
No flashy displays, nice-looking rims, spoilers and catchy body arts like F&F II and III-Tokyo Drift. Just watch the movie and look how fast they run!
