deja Posted January 26, 2006 Share Posted January 26, 2006 My '77 280Z is in bad need of suspension work. No real clue on the mileage on the car, odometer says 91,000 but the previous owner did not know how accurate that was. What is your opinion on poly bushings vs. stock style rubber bushings? I have heard the poly bushings are the way to go but have also heard there is a huge sacrifice in ride quality with poly bushings. This car, although it does have a Chevy 350 in it, is a daily driver so I don't want to end up with a race car suspension on a street car. My plan is to change all the bushings, shocks and probably the ball joints while I'm in there. Quote Link to comment Share on other sites More sharing options...
blueovalz Posted January 26, 2006 Share Posted January 26, 2006 There are so many bushings and isolators in the suspension that I believe this is the reason I found no ride quality difference between the rubber and the urethane bushings. Now, start changing springs, dampers, and bars, and that's a different story. Quote Link to comment Share on other sites More sharing options...

One of the first things you might want to utilize, when looking for answers, is the "SEARCH" function. There are alot of questions that get asked repeatedly and have been answered many times in past posts. You will discover a wealth of info in the old posts! Give it a try. Back to your question.....polyurethane bushings are certainly better than the stock rubber units. One misconception is that they yield a harsh ride. I for one don't believe this is an absolute truth. They do minimize unwanted suspension movement, providing more consistant suspension geometry, and they won't degrade like a rubber bushing will over time. I think that super low profile tires, stiffer springs, and shocks with higher damping rates give you the harsh ride! If you choose to go with the poly bushings, be sure to use the lube that is usually provided for the bushings....otherwise you may wind up with a squeek monster. Have fun with the install and remember to use the search function. Quote Link to comment Share on other sites More sharing options...
deja Posted January 26, 2006 Author Share Posted January 26, 2006 I've been lurking on these boards for a while, mostly on the V8 board since that's what I have. I'm not running low profile tires now and don't plan on any "trick" shocks or springs. I knew about the lube thing for poly bushings and will be sure to use it. I've never run poly bushings on anything I've owned so I just wanted to be sure I wouldn't be building something too hash. I want it to handle, just don't want my filling jarred out, LOL. Years ago I race a Sunbeam Tiger that I also drove on the street. Got stopped once for "dodging" manhole covers because the shocks were so stiff. The cop took no pity on me and wrote the ticket for careless operation anyway! Quote Link to comment Share on other sites More sharing options...
