Default Re: Subframe: Front vs. Rear mount brace

I reinforced front and rear subframe mounts. I ran bolts up from the existing threaded inserts through the trunk floor. Then I used a 6 x 6 x 0.75" thick sheet metal and riveted
that to the existing 0.032" thick top sheet metal. I used 3/16 stainless rivets. In the front I had to make welded pockets in the sheet metal so the nuts could hold to flat material.
Underneath I made my own reinforcing plates and epoxied them in place and riveted them as well. Now the forces are being distributed in a much larger area and twisting will be difficult because of the top reinforcing. It does seem few people ever do the front mounts from the top.
