The weather is slowing turning up here in Chicago. I have the Kinetix front control arm and rear camber/traction arms and the SPC toe bolts ready for install. From what I gather, while not being beautiful, the Kinetix arms are effective in getting ours cars back in spec. Polyurethane bushings are better than the stock rubber bushings, but they are higher maintenance. They tend to make noises under stress. Some of you have Kinetix arms and have gotten the noise down quite a bit. I'm having a local shop do the install, but I need to know what grease to use on the polyurethane bushings. I wouldn't dream of installing them without some kind of lubricant. I was told a marine silicone-based product might do the trick. What are your thoughts?
