Japanese car tuning

Just to remeber you I copy here Wikipedia definition for car tuning:

Car tuning is both an industry and a popular hobby, in which a car is modified in order to improve its performance and handling. Car tuning is related to auto racing, but most performance cars never compete. Rather they are built for display at motor shows and club meetings, or just for the pleasure of owning and driving such a vehicle. Another major part of tuning a car is the body work. This includes changing front, side and rear bumpers, adding spoilers, alloy wheels window tinting, neon lights, sound systems, seats and just about everything else that you can change in a car.
