As for the motor mount inserts, I don't think the wear is anything to be concerned about. I didn't even think about that until I read your post. I bought them used. They looked just like that when I first installed them. Took care of most of my wheel hop, but I only put about 1000 miles on them before I filled my mounts. They've just been sitting around collecting dust ever since.
Anyone know anyone who can help me tune this in the Pittsburgh area (Greensburg)?
