OK...I know you guys get mad when people ask questions that have already been answered. I have looked at bushings topics and not really found what I am looking for. I will be installing the ford racing KW struts and shocks with H&R sport lowering springs very soon. Since I will be ripping my suspension apart I am going to replace bushings. The energy suspension bushings are polyurethane and the prothane bushings are urethane. The prices are similar. Does anyone know the difference and which is better/worse in which ways. I will be buying bushings and I'm not sure which way to go. Help is appreciated. P.S. sorry so long...
