Hello,
I've bought someone elses project not to long ago, which came with a shell already sprayed in a underbody coating and sitting on both subframes.
Despite me removing and rebuilding both subframes, I didnt notice the spacer in the photo before as the coating effectively holds it in place. I didn't notice any stress while aligning the bolts and doing them up either.
Now that I was doing up the rear brakes, I suddenly spotted this spacer plate between the body and the subframe mount and don't recall seeing one in the schematic pictures. Obviously someone made one to fit, so I wonder if I'm just overlooking the fact that they should be there in the first place or if there is a good reason to make and install one..
