I recently got a '71 Swinger, and I want to rebuild the front end and add a sway bar if possible. I've been looking at the kits from Performance Suspension Technology, and think I want to get the Polygraphite Super Front End kit. I also want to put disc brakes up front, and am considering getting the power brake kit from them also. I guess my question is, are there any real benefits with the polygraphite kit over the standart? I heard that polygraphite bushings make a lot of noise, but I can't remember where I heard it from. I also looked at the kits from Just Suspension, but they're like $600 more. Are they any better than the PST kits? I also want to replace the shocks at the same time. The cars only got a 318 in it for now, but I may put something bigger in later on. I just want to improve handling on the street. What should I do?
