What are your thoughts on the longevity of these pieces?
UMI Performance makes mounts similar to these
for the 1st gen CTS-V. And before they started making these, a guy on cadillacforums.com made some that were basically the same thing. I don't know how many sets of them he sold, or how many UMI has sold, but I have yet to see anyone post of an issue with them.
And if there is an issue, it should be pretty easy to pull out one side at a time and replace the bushings.
