Very easy if you already have a very rare item
-To check if you do, from the main menu click garage and then manage inventory
-Click LT to show your filters
-Click the quality drop down menu
If you have a very rare item it will display how many you have next to the very rare option.
As long as you have at least one you can get this achievement.
Make a note of what it is and click on customise car and equip it to any car you like.
If you do not have one you will need to keep playing until you get one, trade with a friend or someone willing to trade with you online.
On the main menu click EXHIBITION
-Set the game mode to soccar
-Scroll through the arenas until you find one with (stormy) next to it
-Team size 1v1

-In the mutators settings, change max score to 1 goal.
Create the match, score a goal, and you will get the achievement after the game ends.
Hope this helps :)
