Poly Engine Mounts

Anyone interested in getting a set of poly engine mounts made for ~$52, please show your support in the poll.

We would need 20 orders at minimum to try this. Price is only a guess at this point. Will get a more accurate quote if there is interest.

Thx,

AA

Series I and II the same??

Good question, Jack. I'm not sure yet. Until we know the differences, this is for Series II only.

HELL YESSS

all 4 mounts? Which mount are you thinking about? I'm interested...

If we do 4 mounts (tranny included) it would be closer to ~$52 for the set. Again, I haven't verified anything yet. I think it would be wise to do the bushings first for the reasons pointed out.

Eric, please DO NOT purchase OEM parts until we have enough votes to move forward. We do not need to have these parts until everything else is in place.

I am so in on this and need them fast.

At $52.00 per set, everyone should get them just to have on hand.

Im in!!!!!!!!!!!!!!!!!!!

As for the series 1.. Check Gmpartsdirect... I am pretty sure the 2 of the 3 Transmission Mounts are the same (front and rear).

defiantly in! $52 for a set is cheaper that 1 OEM tranny mount.
and if anyone in FL needs a hand replacing the one by the belts let me know (im a pro at that one now )

so the only draw back to poly mounts is more cabin vibration right?

And I wouldn't call it a mild vibration. I noticed increased cabin resonance when I hooked up my FWI tube. I would think solid mounts would cause the car to become a buzz-box. Maybe I'm wrong... I sure hope so.

Keep in mind guys, we're doing the rear stabilizer bar bushings first, then moving on with these mounts. So, if you want the mounts, put in your vote for the bushings here:

Thanks! It will be awesome to see these parts on our cars. Can anyone confirm if the Series I mounts are different or the same as Series II? Maybe only one or two are the same?

so what exactly will poly motor mounts do??? make it move less under the hood?

They make the motor/tranny move less, so the car moves more. You can Interpret that in at least two ways.

so it will launch better?

In theory, yes it could.

i once had a theory.........

What if I wanted to make my car faster but had NO money............... i could pull it in the garage and sit by it , light some candles and do a voodoo spell.... AND BOOM 12's...... but hey its JUST A THEORY.....................



im down...

I voted yes. While my tranny is out I closely inspected the mount and even though it appears to be holding okay I can see many cracks in the rubber.

just curious how this is going. I need to replace my rear mount and I guess I'm just going to have to get it now. I was hoping to hold out until this mount was ready...

I will check with a couple shops I know do poly molds. Hopefully with 10 guys looking at making a purchase we can get a group discount. I also ran across a guy who did mounts himself for a GTP. With his help, I plan on doing a mold and casting myself if the other shops are wanting too much. His turned out great adn he is very knowledgable about the process.

Even a solid rubber mount would be better than the diagonal thingybob that's back there now. I can snap a few closeups while I have the subframe out...

The two we looked at were the passenger side and front mounts. If you can send photos of the others, I would appreciate it. It would help us determine what kind of molding process or machine work would be necessary and most effecient for all four at once.

I'm interested, but have no money as of right now. When I get a job I would definitely buy them.

Eric, if you want to pursue this on your own, that's fine. If we use my source, I want to try them with the rear stabilizer bar bushings first. If those pass the test, we would talk about engine mounts.

AA,

I've located a few shops that will consider doing the job plus someone who has custom made poly molds himself. I will see where this goes and let you know.

Fair enough. See what kind of price you can find. I'm not interested in purchasing any just yet, but I'll help out if needed.
