S13 Subframe Bushing Washers

[tonee]

I removed my subframe to remove the oem bushings and to put in Energy Suspension bushings. I removed the subframe about a month ago and forgot where these gold washers go. Can someone help me figure out where they go? Do they go in the front set of bushings or the rear? I think its the front because the rears are bolted up like this

There are only 2 washers pictured but I believe there are a total of 4 of these washers (unless I lost some).
