I have a question:

-What do I do with those 0-rings?? there's 4 thick ones and 6 thin ones. Where do I need to put them at and do I need to use them at all? What are their purpose?

Thanks.

 

they go on the top and bottom or the springs, between the bottom of the spring and the top of the coil over, and at the top of the spring and whatever its resting against, i didnt use mine cuz when i was putting them in the springs always pushed them out, so i said f* it and left them out of my assembly, not a huge concern if u dont put them in.
