The so-called siege, in fact, the air spoiler assembly. It originated in motorsport, because high-speed vehicles will encounter more air resistance, and surrounded by large can improve airflow around the body, improve vehicle stability. Surrounded the car is a glass fiber reinforced plastic, turbocharger manufacturers spray paint and body-color rear and seamless body, compared to the original vehicle bumper grade is much higher. The installation of the siege, the first by the owners determined according to their own favorite conversion program, and then modified by a professional construction company, generally after molding, brushed steel, repair mode, putty, paint and other processes.

In the installation of the siege, the surface finish and firmness from two aspects to consider when choosing surrounded by large products. Another point to note is that the poor impact resistance of fiberglass, so selecting surrounded by large ships do not remove the original car bumper products. Such safety of the vehicle will not be because of the installation of the siege and lowered.

Insiders said that the siege on the domestic market or for most beautiful and designed to improve vehicle aerodynamics effect is unlikely. Therefore, when the owner of the installation, but also need to consider the needs of their own, carefully selected tuning company. According to different grades, turbocharger suppliers the price on the market, ranging from the siege has three or four hundred to two thousand dollars.

Nowadays, many vehicles have a tail like a bird tail cocked prominent thing, and this is the car tail, learning called spoiler. Do not think the tail is decorative effect. In fact, by acting on the air under pressure generated by the tail, you can control the car go up, making the car close to the ground with, thereby improving traffic safety, there are fuel-saving effect. Most automobile tail are made of glass fiber or carbon fiber, lightweight and tough material whose shape and size is determined by the designer to accurately calculate down. Tail too large or too small will not achieve its proper role, but even increase resistance to vehicle traffic.

Tail car is also a wide range, generally higher car tail installation. This is to allow action will not tail under pressure again in the role of the vehicle body and counteract the tail effect. For vehicle speed is not very high, turbo suppliers the tail is more beautiful role to play. Installation of car tail press materials, the quality of different price from the hundred to a thousand dollars. In addition, the installation of skylights in the past is also a common modification to the vehicle exterior. But according to the new regulations issued, the installation of skylights vehicle owners themselves will not pass inspection. Fortunately, many automakers now launched a skylight version of the model to meet the owners desire sunshine mood.
