poly or stock bushes

[SupraMan1784]

this is the information i got from a friend that owns a 95 rx7 turbo...now keep in mind that this is for a mazda...not necessarily a supra...he told me that though the polyurethane bushings stiffen up your suspension... they dont last as long as the rubber bushings, the polyurethane tends to wear out a lot faster...rubber bushings are also more expensive since they last longer, also he was tellin me when teh bushings get broken in...sometimes they start making a squeaking noise....this guy knows his stuff and ive known him for a while hes pretty knowledgeable..now i hear good stuff and i hear bad stuff about polyurethane bushings...this is just a bad....but remember is for an rx7 not a supra...might be tru for all cars..might not im just gettin some information out for general ideas thats all....hope this helps
