I left my Spinner about an 1/8" higher than the centered position on the cowl. After 150 hours, I am now about an 1/8" lower than the centered position. It is enough that I am getting bugs deposited on the upper radius of the cowl at the spinner interface, so getting a small drag penalty. I also notice that the clearance between the cowl and spinner has shrunk on the bottom, indicating that it is tipping downward/forward and not just straight down.
I am wondering what the best or recommended fix is. It would seem that adding a large washer under the lower rubber mounts would be best, but could also add washers at the lower engine / firewall mounts. I just don't know if that creates any structural issues. If I put washers under the rubber mounts, can I get away with slots in them to ease the installation?
