Finally got the poly motor mounts installed. Man they are great, but they suck putting it. I have Pace Setter LT. I had to take both brackets off the frame to get the motor mount shell out. I thought about taking the headers off, but my ORY fits so tight I did not think I could get it apart or back together. The driver side was the worst. I honestly at one point wished I had not even started it, but it sure helped. No more Y pipe banging, the engine does not even rock or roll when you flick the throttle. The passenger side was so much easier. The A/C compressor will sit on the sway bar and you have much more room than the other side. When attempting this install schedule breaks because you will get frustrated, and tired if you are on a creeper doing this.

ive not heard of false knock with them either, i would think it would be the opposite, we were getting false knock before the poly mount due to headers hitting kmember.
it was a pita install, it does help to have a 15mm gear wrench for the bolts or youll be there all day. also the rivets in the mount took us forever with a die grinder, save your time and just drill the rivets out. otherwise a very good install to do if you have a cam.

I have them too... really shored up the engine motion and made it so the exhaust didn't rattle around all the time.
The one unfortunate side effect is that the vibrations from the engine will be absorbed more into the frame... so I have more squeaks and rattles now in the cabin than I did before the swap.

But hey, at least I have ZERO wheel hop and my car will liquify my street tires if I push the pedal to the floor at any time in first or second gear... and will light 'em up when I downshift from 4th to 3rd.

I had the motor out of the car but I've got to fix the mount because the welds my engine shop put on it broke..
There was no material, it just kept hitting the metal part of the clamshell. I questioned one of the guys at Speed Inc. several times to make sure they were sending me the correct ones.

I have prothane poly mounts and they fit right. Now you wont be able to put the clamshells back together until they meet up by hand because then they would be a solid mount. You will have to pull them together with the new bolts. I put grease on mine before I put them in the clamshells and then tightened them with my small impact gun.

I just did my driver's side last week and I agree...it totally sucked. It took me a good 6 or 7 hours for that but 99% less y-pipe banging now (just the occasional tap starting from a stop). I'll sell my leftover passenger mount (identical to the driver's side) if anybody wants it...there's no way in hell I'm going through that crap again just for the passenger side.

I just installed the Poly mounts on my car, and it was somewhat a PITA .... but I was installing headers anyways so I figured "now is the time". I won't know until about mid April, how the mounts are - when I put the car back on the road (I don't drive it in the winter/salt). Oh, and... GearWrenches Rock!

I have a set ready for install, but after looking at my headers, I don't see how you can fit a wrench in there to take off the upper engine mount bolts. I wish I had done this when my headers were off.

Oh it is possible! I have the same headers, but if you can get your exhaust apart it will probably save you some time from getting the top eninge mount bolts in and out.
