Motor mounts and transmission mounts

Recommended Posts

Can I get a concensous on Motor mounts and transmission mounts.

My car is going on 63k miles is my DD for most part and sits on X74 suspension. I am looking at doing motor mounts in next few months what would you guys suggest?

1. GT3RS

2. WEVO semi solid

3. OEM

What about trannsmission mount? I have heard Porsche now specs a newer 997 mount? worth it? How big of a job is that?

I recently replaced my original motor mounts with semi-solid mounts from RSS. They are similar to the Wevo semi-solids (from the research I did ahead of time). They were roughly double the price of the stock mounts but the reviews on them were really good.

I've had them in for over a month as a DD. Overall I'm happy with my decision and would do it again, although are definitely some negatives. I do plan on taking the car to the track later this year and I'm expecting a slight improvement. The positives are:

  • Slight improvement in handling even on the street. The car feels just a little bit tighter around corners
  • Shifting is a little smoother and it got rid of the the judder of a sloppy shift
  • Engine noise in the cabin has noticeably increased under throttle, but I think that is a good thing. It sounds much more raw like I had expected a 911 to sound in the first place :-)

There main negative is that engine vibrations are now a little more noticeable. I can now tell which RPMs result in the most vibration....~3K is probably the worst. Cabin noise is also a little louder which is a positive under throttle, but not quite as ideal when cruising. Neither are a big problem and they make the car feel a little less than a GT and a little more like a sports car.

The Rubber bushings in the transmission mount in my 02 were totally shot at 90k miles. IA new carrier is an easy installation and my local Indy only charged me $75. My only trouble was that there are two little rubber-like tabs that Porsche calls Trans Carrier Stops that were also bad. They did not come with the carrier assembly so I had to reorder and get them installed later (again $75). Pelican Parts furnished everything.

I installed the WEVO's and although you definitely notice more noise and vibration at idle, they got rid of some slop in the rear end when doing spirited driving. If you don't push it hard and want to keep the daily driver feel and quieter cabin, go with the stock units.
