Go to Freelancer/DATA/equipment and open "select_equip.ini"
Then go to the bottom and add something like this:
[Armor]
nickname = armour1
ids_name = 263737
ids_info = 264737
hit_pts_scale = 2.000000 ; <-this is what the your armor is multiplied by 1 means no armor change, 0.9 and lower decreases your armor, and 1.1 and higher increases your armor.
material_library = equipment\models\hardware.mat
DA_archetype = equipment\models\hardware\br_protective_armor.3db
volume = 0.000000 ; <- change this to make it take up cargo
mass = 10
lootable = false
Then in the equipment folder open up misc_equip.ini and put this at the bottom:
[Good]
nickname = armour1
equipment = armour1
category = equipment
price = 100000
item_icon = equipment\models\commodities\nn_icons\EQUIPICON_armor.3db
combinable = false
ids_name = 263737
ids_info = 264737
shop_archetype = equipment\models\hardware\br_protective_armor.3db
material_library = equipment\models\hardware.mat
Then in the equipment folder open up market_misc.ini and find the base you want to add it to and paste this this below it
MarketGood = armour1, 1, -1, 10, 10, 0, 1
There ya go
