Assuming that the eight 1/4" thick washers are extras and that the kit has eight 5/16" G8 washers, then those are "bonus" parts. They are from the MMCC9994 kit and should not have been included with the adjustable rear swaybar.
Feel free to do whatever you would like with them! Please check over the parts list on page 9 of the installation instructions. If you are missing any parts, PM me with your name, address, etc so I can get the missing parts shipped to you.
