At the inside end of the arms only, I can't believe it makes much difference. Front half of the strut rod, sure as hell does. I'm running half poly half rubber in the Classic, no choice really with the stock strut rods. It's noticable. Also I got a lot of urethane groan, for years, it sounded just like a crapped up worn out suspension it was so noisy! I finally found that a disc of 1/16" teflon sheet (the real stuff, made in the 1960's, I got surplus from Los Alamos Scientific Lab) shut it up and isn't squirting out from the pressure. It's been in there for months now and still silent and still there. I know (I think) that AMXs and later Americans have a bushing at the trunnion, with that urethane I dunno, but it would have to be a bit harsher. I think worse is that for my Classic as far as I know you can't get the rubber cup insulators for the spring to sit on, I think that would quiet a lot of road noise. My classic is a bit like a truck now. -------------- next part -------------- An HTML attachment was scrubbed...
