I have a question.

I'm researching suspension options for a 32 ford and I have noticed that almost all kits (4-bar, ladder bar, hairpin, etc) use urethane bushings at all points (exception being clevises on some). Is everyone using bushings for a reason other than they are cheaper than heim joints? I would assume this is true except that I have seen most "money is no object cars" in magazines using bushings.

I have also read that urethane really is not that good of a bushing material because it binds during nonlinear movement and also needs constant lubrication.

Basically, whats wrong with using quality heim joints everywhere?
