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 ;)

That I understand, but in de EP1145 set are these also, are these not good?

The PU set that I had was not from Pedders. But spending $150 just for tying out is little to much.

They're different, the ones in EP1145 sit are a smaller diameter than EP1168.

The fact that you didn't fit the Pedders ones is probably where your NVH issues came from. They have been designed to work on the VW to VZ Holden Commodore in coupe, saloon and estate chassis as a direct upgrade/replacement for the original bushes.

If I ever bought another Omega I would fit them again without hesitation..having fitted them to three of my estates... 2x 3.2 and 1x 2.2. :y

Probably.

Okay I will keep that in mind.
Perhaps I will give it a go, you never know.
