I changed to poly engine mounts after the sidepipe mounts broke a couple of times. Dennis Olthoff had suggested the switch to poly after I called for a solution to the sidepipe issue. I never had problems with the pipes hitting the body panel. One of the rubber engine mounts was cracked when I took them off. I never had the problem in the SPF with the 351 I previously had. It's the monster torque of the 460 and other big block installations that I think Superformance didn't anticipate in designing the engine mounts.
I do feel a little bit more vibration transmitted to my seat but that's OK.
