Quote from Bob Smith :

I'm not sure I understand your question. It doesn't matter if you have an S1 or S2 licence, you can use add-ons in exactly the same way. You're better off picking a specific add-on that you want to try, and then asking a more specific question, so you can get a more specific answer.

Btw, you can log into the forums with your licenced account with the same details you log into lfs.net with.

ok i can be more specific.
im trying to install the drift gauge addon displayed here:
