BMR poly motor mounts NVH - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So I just got a bunch of work done to my car; cam, headers, under drive pulley, and BMR motor mounts. I do daily drive my SS so I decided not to go with solid motor mounts since they would be very harsh. The poly motor mounts though also seem to be very harsh. It's not terrible but the vibration and noise caused by the vibration is a little overwhelming. I've only driven on them for maybe two days so they are not broken in yet but has anyone run with them and noticed them get more forgiving? I want to feel the cam lope and the whole car go with it but right now it just seems like the vibrations drown all of that out.

The cam bears part of the blame but within a few hundred miles the poly should loosen up a little.
