Prothane motor AND trans mount
How's it going guys. I have been compiling parts for my return from Afghanistan, and one of my purchases were prothane motor and trans mounts. I have read mixed opinions about running poly motor and trans mounts. Some guys say do it, others say run poly motor and rubber trans. WHAT IS THE REAL DEAL. Do I want to run both poly, or rubber trans mount? I bought them as a kit, so it would be ideal to just install both of them. The car is my daily driver, but I do not mind some added vibrations if it helps performance wise. The car is an a4.
Thanks in advance.

I just installed the poly trans mount, I love it. But then again I'm running an m6. The vibrations make the car feel more alive, it shifts smoother and there's no more tran movement. But again that's on an m6. I have the motor mounts also, just haven't had time to install them. But I'm eager to get it done.

I am just worried about having poly for the engine AND trans mounts..

I have poly motor mounts, trans mount, and torque arm mount.
I feel that all those poly components really tightened up the car and didn't add much (if any?) noise. In fact, my car made more noise with all the slop in the drivetrain due to the weak rubber mounts. My car is more of a "cruiser" than a drag racer or auto-x machine, and I wouldn't hesitate to install all the poly pieces again.

This is gonna all come down to personal preference, I think I would go ahead and try it. If the vibrations are too much for you, pull the trans mount back out and go back to the stock rubber. Replacing the trans mount isnt that much work. Im doing the poly engine and rubber trans on an A4. After the engine goes back in, if vibes arent bad I might try that trans mount as well. My advice is feel it out.

whatever you do, do not use a poly trans mount with rubber motor mounts. i believe the rubber MMs let the engine twist while the poly TM does not. putting the stress on your tailshaft housing. i have some good pictures of what happens when the 2 disagree. i think i even made a thread about it a few years ago.

BUT...you can use a rubber trans mount with poly engine mounts.

Prothane motor mounts add weight to the car i heard...dont do it.
You should swap in a 7 speed transmission, more gears and you'll go faster. better bang for buck.

I just finished doing the motor and trans mounts in my wife's car. It took me 3 days to do it by myself... granted that was 8 hrs spread over those three days - semantics. The two things I will add are:
1. This isn't for a novice, especially not one lacking patience. Take the whole assembly out and re-install from the top down (motor to pedestal) with everything loosely installed; and
2. Yes, it transmits more vibration through the chassis... but, at least you know the engine and trans will stay put. Our stockers were hardened, crumbling and split.
Good luck!

Get a torque ARM bushing also, trans mount is easy install, motor mounts helped a lot!!!! But they suck for install, get help cause Ur gonna get stressed and its gonna take awhile, has nothing to do with mech skill level just a ***** to get to bolts

I'm going to be doing the engine and trans mounts at the same time. Both will be done during my header installation. I'll have my father helping me out so I don't think it will be too much trouble.
Not going to get a torque arm bushing, as I will be getting a UMI torque arm as soon as I have the cash.

I ran both poly motor and trans mounts on my old Camaro for years - for the trans mount, I did not use the preload plate.
The poly mounts seem to "break in" after a while, so if you don't like the vibration, just give it some time. Swapping back to a rubber transmission mount is far easier than trying to do the motor mounts again, so you can easily reverse that portion of it. The poly motor mounts, IMO, were a must. As a matter of fact, I'll end up doing poly motor and trans mounts on my Viper once I get some time.
