1. Start game.   开始游戏
2. While at the screen that says "CLICK TO CONTINUE" or "MAIN MENU", type
in the desired codes below, for the desired effect you want.    在"点击以继续"画面或主选单输入以下密码

inthezoneskin = Autozone Vinyl Unlocked!  解开
syntecskin = Castrol Syntec Vinyl Unlocked!  解开
*5grand5grand = Castrol Cash Unlocked!  解开

Note:

Codes marked with a * is confirmed working, the others might have to be
activated by another method. Someone suggested that they might work with
an EA account, but since i don't have that, i can't test them. Codes with
* don't have to be typed with a *, just in case you're wondering.
*不是密码的一部分,在这只作一个提醒

Another issue with the codes, is that when you type one wrong, it's like,
it's blocking and you can't type others. Only solution to that, is to
restart game Frown
如果你打错密码,必须重新再入游戏,输入密码

We decided to release the codes for you all now, since the demand is high,
maybe you can see the light in getting the others working? Have fun Smile
这项不关游戏和密码

Special Note:

The 3 last codes wasn't found in the main game exe, if you look a little
deeper, you will find them, you actually need a tool other than notepad,
before you can be successful.
这些密码大多(不包括最后三个)都可以在游戏目录找
