I drove about two weeks with poly's and it was driving me nuts, to much noise and vibration.
Handling was awesome but not the nvh so I switched back to the original ones.
Just asking why also these Pedders EP1168?
They sit between the subframe and the chassis and are far more substantial than the original slice of rubber...
Also the design of the later EP1145 has changed slightly from the original ones. Some people found that the earlier ones eased out slightly and needed monitoring.
No such problem with the current ones fitted with EP1168 as together they ensure the subframe is fixed in position. No NVH issues with either on my cars, (both estates... 1. Early EP1145 and solid rear diff mounts, 2. Current EP1145 and EP1168 with original diff mounts).
Basically EP1168 prevents the front of the subframe from riding up under load whilst EP1145 controls and lateral forces... these being the disconnected feeling you get from the standard bushes as they degrade
