To activate the spoilers you need to install
[url = http://www.gamemodding.net/ru/gta-iv/gta-iv-mods/5963-epm-v16.html]EPM v1.6 [/url]
The spoiler is activated automatically when driving cars at high speed.
After installing the EPM v1.6 and auto, you must know the serial number of the car that you can get during the game while in the car and then pressing Num 8.
When the value is received (in the upper-left corner of the monitor) without shutting down the game collapse it and enter the folder with the installed game, in the scripts folder, open movedoors.ini in Notepad.
Next, enter this string:
XXXXXXXXX, 2, 30, 18, K, L, 1, 1, 1, 1, 0, 0.05, 0.25, 1, 0, 0, 0, 0, 0, 0,-0.24, 0, 0, 0, 0, 0, 0, 0, 0, 0, HAMANN HAWK by _HAMANN_
and instead of XXXXXXXXX to write the resulting order numbers.
[color = #CC0000] Attention [/color]! If the numbers specified here is the sign "-" (without the quotes), then this means that it will need to be fit.
