Installing Rubber Bushings (Page 2/2) pmbrunelle MAY 18, 11:31 PM quote Originally posted by 82-T/A [At Work]: Interesting guys... so, wanted to just quantify what you guys are saying... REAR CONTROL ARMS: You guys recommend keeping poly on the rear control arms. SUBFRAME: Poly FRONT UPPER CONTROL ARM: Rubber? FRONT LOWER CONTROL ARM: Poly? I don't want to hijack this thread, I think cvxjet did a good job (where can I buy those spacers?)... but if ride quality and handling were both important (meaning that you wanted the car to perform well, but you were now in your mid-40s and your priorities had changed)... would the above be correct? My opinions... I don't like compromises too much, I want the cow, the milk, and the butter that goes with it. REAR CONTROL ARMS: Poly. Not much load at rest. Good to have stiff to keep the rear end stable. SUBFRAME: Poly. Metal works too, but I think the poly is stiff enough. Forces are smaller in magnitude than at the rear control arm bushings. I think poly is better than metal for future serviceability. FRONT UPPER CONTROL ARM: Poly. Not much load at rest. If this bushing is stiffer, than there is less loss of camber in cornering. I suppose that rubber here could be OK too. I don't think that the choice of bushing material in this position will have too much effect. FRONT LOWER CONTROL ARM: Rubber. The weight of the car bears on these, so I think this would have an effect on ride quality. Pivot axes in 84-87 not collinear, so unsuitable for poly. 82-T/A [At Work] MAY 20, 09:26 AM quote Originally posted by pmbrunelle: My opinions... FRONT UPPER CONTROL ARM: Poly.

I was really hoping your recommendations were going to reverse these... hahah... it was such a pain in the ass getting those WS6 springs on without messing up the fancy red paint on them. Fiero_Adam MAY 21, 01:28 PM I actually did this myself years ago, but I only changed the front bushings back to rubber. The replacement rubber bushings are incased with the metal sleeve, so you press out the sleeve, while using some type of backup spacer (I used cut pipe also) to keep the arm from deforming. Much better and less noise, at least from the bushings. Still an old car with squeaks and rattles.
