New car maintenance knowledge - need plus lexia 3 tail?

Tail, also known as the tail wing, was first  lexia 3  seen mounted on a high-speed racing, and later some car production plant is also part of the three boxes, two boxes car applications. Tail the wind wing in the role of high-speed airflow for high-speed vehicles do have the role of the stability of the rear of the vehicle, but there is a premise; That is the the windage shape and set the speed of the car to have a precise fit, otherwise, it is futile.

Due to the emergence of the tail wing, causing part of the attention of fans and hobbies, and more important to do some car decorating business boss that this is a market, but also significant graphic.

So the market wing of the different styles can be optional, but have one thing in common: a tail wind wing can be applied to conventional urban road speed, it is impossible to adapt to an amazing array of shape at high speed.

So; various tail wing only appreciate the value of no practical significance. As to appreciate the value of different opinions, some   obd2 scanner   people think that good-looking, and some people think ugly.

I've seen a comic:

Painting a large tail wing mounted stop the car in a little low, who can not read; aviation home over shook his head and said: "It does not fly up, not the aircraft; strategist over shook his head and said:" It not weapons, firing not missile "; Wrangler in turn shook his head and said:" bolt horse and too thin! "decorating boss in the side laughing:" are the SB, I relied so rich! "

Although this is a cartoon, but also shows that the tail wing is useless, especially some very exaggerated tail more than the width of the vehicle body, blocking the line of sight, the driving is very unfavorable.

As for the value of   Diagnostics OBD2 appreciation, a layman looked puzzled, not to mention good-looking. The insiders know useless met, only bared to laugh. Only themselves and kind friend appreciate the Shihai complacent, I feel like the emperor's new clothes. But the emperor has no clothes feel or have a price, and that is this car to go, there is a sign, car repair and decoration met so that the Lord will never be soft, fat-site!
