… do you have the poly bushings and bolts that get rid of the notorious clunk? ---

I put poly bushings in the front of the irs, but I did not do the aluminum rear. I read too many “too noisy/viberation” reviews. ---

did they make a big difference? i’m not a fan of the alum either. i’m gonna try MMFLSFC and the MM poly’s front and rear. go from there. try posting this on svtperformance and modeularfords i’m sure somebody there will want it. ---

I grenaded the aluminum rear so I replaced it with the iron. The poly bushings did help but the stock bushings needed to be replaced regardless, so how much they helped, I really don’t know. ---

I’m sticking by IRS (cuz my car makes no powers), but it doesn’t seem real common to try and make it work. sorry for the off-topic education, but free bump for you! ---
