You will only get the picture of it installed because I'm not removing it again.
Hopefully you can see in the previous pic how simple it is.
....black urethane was what I got. It'* badder.
This has got to put more power to the wheels quicker instead of being absorbed by the mount.

My other car was fitted with all red urethane bushings over 20 years ago. I won't be using red urethane bushings on my Bonne.
The black graphite impregnated ones are superior.
The red ones are the same hardness but lack the lubricating properties of the black ones. Every few years I have to take them apart and lubricate them because they squeak. They didn't come with grease fittings that the later versions came with. :(
And because you have to lubricate them, they get dirty. Black will hide the dirt of age. Hmmm...profound.

Now that I've been driving with the solid mount for a few weeks I have noticed one annoying feature.
When the engine upshifts to OD and the lock up torque converter pulls the rpm down to 1200, I can feel an slight vibration. It doesn't stay for long and disappears once the rpms rise to 1500 or so.
A small price to pay for better throttle responce and zero engine movement. I think it even helped my torque steer.
I will always remember the scare I had the first time I drove an STS and punched it at highway speed to pass a car. The damn thing shot into the left lane without me even turing the steering wheel. The Bonne now has more pull than that car had but doesn't torque steer near as bad.

I just changed mine with another factory one because the rubber had all disintergrated (62,000 miles). However i jacked the motor up to take the pressure off, and began taking everything off. Well to make a long story short the jack i have SUCKS and leaked down, however I never noticed it becasue the engine never moved. Is this normal? Also i've found oil on the right front suspension arm just all puddled up, I'm wondering if that'* from the engine mount on that side? There was no where else it really could have come from and hasn't been back since I cleaned it off.

Nice looking car.
I also had oil inside that right front lower control arm. I noticed it the week after the car was first purchased new.
I has done this a few times over the years and I'm convinced that it is from the supercharger vent in the end of the pulley. I think that it blows out under pressure and heat. It hasn't done it since I adjusted the oil level. If you look, you will see that the vent is directly above the control arm.
No, the side engine mounts do not have oil in them, only the front one. The side ones simply allow the engine to pivot.
Check your supercharger oil level. When I checked mine after only 10,000 mi, it was down almost a full bottle. I think it ended up on the control arm.

Thanx except I have no where near the mods you do !! I'll have to check the supercharger level this weekend when i put it in to do plugs, wires, fuel filter and start on my CAI. Love the ram air induction set up. How does it work out for you? Is it a noticeable difference?

You're welcome.
The ram air worked out great by reducing the temp inside my cool box to outside temps. Without the ram air, the temp was about 10-20*F warmer....and as we all know, for every 10*F drop in temp, it equals 1% more hp across the entire rpm range. It will also be picked up by the IAT sensor and should reduce the knock retard during the warmer summer months when under hood temps can get over 130*F.

Hmm thinking about trying this as I have access to a machine shop and a machinist that can and will make just about anything. However, would going to with a 3" x 1" with two 1" thick pieces of urethane work? I would think that may make it a bit softer and might not have as many vibrations. Something to try I guess.
