Message	I'm optimistic about the new design. I was already committed to trying all poly bushings this time around and had ES Poly tension rod and LCA bushings up front. Had fresh Nismo FUCA bushings installed since there wasn't a good poly option, but have been worried about using the combination of rubber and polyeurthane on the same assembly causing vibrations. I think you want the mount bushing material to be the same on the same arm/assembly, either all rubber or all polyurethane. That's why I jumped on these right away.... So far so good, but lets see in a year.
