I ordered a set of the .9" taller upper a-arms from UMI for my 65 Buick Special. I'm not intending to build a g machine but just wanted it to handle back roads better. I failed to notice and wasn't informed by their technical guy that they only came with rod end attachment instead of a urethane or delrin bushing. My concern is the harshness and noise I have often heard people complain about with solid suspension components. Their tech guy said the upper arm doesn't transmitt NVH and that the delrin bushing would be just as rough. Is this true or should I send them back and get the BMR poly A-arms? I'm not very pleased with UMI right now for some other misleading tack-ticks but figured I would ask people's thoughts before sending them back and going with BMR.
