so my stock motor/trans mounts are shot and im considering getting polyurethane mounts. Im relatively new to rx7s but in my old 89 jetta vr6 swap it would rattle the fillings out of my teeth at idle with all poly. im not looking to get stuck with that again, so does anyone have experience with poly mounts in a rx7 or should i get new oem mounts?

oh and its an s5 n/a if that matters

 

While there is considerable increase in vibration when using poly engine mounts you must remember that a rotary engine runs considerably smoother than any VW motor including the quazi V6 called the vr6.
