Does anyone have polyurethane subframe bushings installed?
CZP is basically claiming the 350z and 370z replacement subframe bushings are the same size. I couldn't find any information on whether or not the overall bushing dimensions are the same, but it seems so since CZP claims all these solid and poly bushings (except the nismo) for the 350z will fit the 370z.

So has anyone actually tried polyurethane or does everyone just install the Z1 collars or go solid?
