Don't do a poly unless you do poly mounts. You will always break a rubber mount if you beat on it with soft motormounts your asking for it. Get a relocation cross member and the problem is solved with a stock rubber mount.

Like he said, the engine and transmission mounts need to be the same, if you put a poly trans mount in with stock rubber engine mounts the trans will not be able to flex with the engine and you will break the tailshaft housing.

I don't think I'm brave enough to try that torque arm relocation crossmember yet... :shiftyeyes:

You must get more noise and vibration inside the car though, right?

How much are poly engine mounts ?

Formula413 08-21-2010 11:20 PM

Around $30 each. They're actually much cheaper than stock rubber mounts, getting them in is the hard part.
