Car upgrading and refitting is not unfamiliar to car owners, but how to refit, where to refit generally, and what changes the performance of the vehicle after refitting in different positions. The Audi refitting store will answer the above questions one by one:

一、動力升級改裝：

1、 Power upgrade and modification:

一般升級動力先從排氣管入手，順序是尾段、中尾段、全段。一般全段都換的話就要配合電腦程序一起升級了。當(dāng)然，還有運動三元催化的升級。然后是進氣系統(tǒng)，可以換成進氣量更大“蘑菇頭”。大廠的配件里還會有專車專用的進氣導(dǎo)流配件。再有增加或更換中冷，增加油冷、泄壓閥什么的。這都是簡單的升級。如果有更高的要求，可以更換渦輪、擴缸等。

Generally, the upgrading power starts with the exhaust pipe, and the sequence is tail section, middle tail section and full section. Generally, if you change the whole section, you have to upgrade it together with the computer program. Of course, there is the upgrading of sports ternary catalysis. Then there is the air intake system, which can be replaced by a "mushroom head" with a larger air intake. There will also be special air intake and diversion accessories for special vehicles in the accessories of large manufacturers. Then add or replace intercooler, oil cooler and pressure relief valve. This is a simple upgrade. If there are higher requirements, the turbine and expansion cylinder can be replaced.

二、操控改裝：

2、 Handling modification:

從簡單的加裝加強件，到升級穩(wěn)定桿、輪轂、輪胎，再到更換避震、剎車等。

From simply adding reinforcements to upgrading stabilizer bars, wheels and tires, to replacing shock absorbers and brakes.

三、外觀改裝：

3、 Appearance modification:

各種拉花當(dāng)然是長見的，還有全車改色，增加尾翼。

Of course, all kinds of lacquers are common, and the color of the whole car is changed and the tail wing is added.

四、.影音升級：

4、 . video upgrade:

簡單的就是升級DVD導(dǎo)航，再到升級音響，加功放，加超低音，做造型、燈光之類。甚可以加電瓶，升級發(fā)電機系統(tǒng)。

The simple thing is to upgrade the DVD navigation, then upgrade the audio, add power amplifier, add subwoofer, make modeling, lighting and so on. You can even add batteries and upgrade the generator system.

五、舒 適升級：

5、 Comfort upgrade:

升級避震也可以算到這個范疇，但是目前升級避震都是為了獲得更好的過彎性能，也就是把避震調(diào)到比較硬，過彎性能會很好，但是舒 適性會降低。但也有些人是會在平時調(diào)到比較軟，有比賽的時候再調(diào)硬。

Upgraded shock absorber can also be included in this category, but at present, the purpose of upgrading shock absorber is to obtain better bending performance, that is, adjust the shock absorber to be hard, the bending performance will be very good, but the comfort will be reduced. But some people will adjust it to be soft at ordinary times and hard when there is a game.
