I am about to commit to either rubber or Poly? Weekend cruiser and fun driver. Tell me more.....I thought with todays technology I'd be better off with poly but your making me think factory will be fine for my pretty much stock 340 Duster.
Personally I think the polys are good for a hard run car because they are tougher and have less give to them.
The reason I used poly in my suspension and not the mounts is that I drive the crap out of my car and sometimes I'm pretty rough on it.
I hit driveways and dip into corners where pavement is missing, along with the roads here sucking anyway.
Bumps dips and rough surfaces are common here, so I knew the suspension was going to get worked pretty hard.
BUT I didn't want all the normal drivetrain vibration going through the car as well, so I suspended the engine and trans with rubber.
My car has spool mounts at all three points and I figured I would take advantage of their forgiveness in the vibration dept.
Poly allows an approximate 1/16 toe because it doesn't give as much under a load as rubber so poly strut rod bushings were used.
