I currently have the AWR front (70 durometer) installed and I have the side inserts in a box waiting to be installed.
I've read that the side inserts will lessen the cabin vibration felt by a stiffer front mount. I personally can't verify this because I haven't installed the side inserts yet but I'll update when I get them in.
You could try it, but I wouldn't reccomend it. I don't know of this happening or not, but I would think that the rear one would be shaken to pieces after a little while if your AWR mounts are too stiff. One could argue that the other mounts would totally prevent this, but the front mount only sits on a support brace and the side ones are inserts....
Of course I'm not speaking from experience. Just a theory.
I just went ahead and bought 95's all the way around after my rear mount AND my left mount went. I can easily say that I wish I had bought them long ago.
you don't have to pull the engine to do the rear, just a lot of people who are already removing the engine for some other reason change out the rear mount while it's easy to do. there's a how-to on swapping the rear mount.
I replaced front and rear. The front was a piece of cake, but the back was a bit of a pain (i didn't get enough extensions). I have the manual front and the auto back. 95 and 88 respectively? Not for sure on the numbers. There was quite a bit of vibration at first, but doesn't seem to be as bad now. Could either be that I've just gotten used to it, or they have broken in. I think I am just more used to them because I have only really driven the car in the driveway and had a friend drive it down the road, and it's not TOO bad. There haven't even really been many miles put on it since I put them in. And the big vibration letting out the clutch is just something where I'll have to change my "slow-driving" style a little. They were SO, SO needed as the front was ripped pretty good and the rear was pretty much non-existent.
Used the thread in the how-to section and it worked perfectly!(first)
