when i looked at Pedro's page, I got the impression he was sending a bracket with the mount alrady installed into the bracket itself. you just unbolt hte one you have, and then bolt in the new one.... is that how it goes?

i'm right now torn between whether i do the enthusiast mount, or go for the new "upgraded" 987/cayman mount. not sure which is ultimately "better"?

i don't mind some vibration if there is a benefit to it, but i don't want to get vibration just to have vibration. some people have reported doing the cayman mount and also being very very happy with the result, and I don't beleive it results in any vibration at all...but maybe the end result is "not as good" as the Pedro mount in terms of improved shifting.

is there any improvement in overall "handling" feel of the car...like when you turn or corner, does the car feel more solid / rigid with this new Pedro mount? I did an engine mount on a prior car (which was also broken) and the result was firmer steering feel...as well as better shifting

just wondering what the results really will be...and what is the best mount to pick

Received mine yesterday, it is the entire bracket. The lower price for "core only" applies if you send in your old mount to be "reconditioned" and converted to the racing or enthusiast mount. I bought the entire assembly since the cost of shipping between Australia and the U.S. for me to return the bracket was cost prohibitive.

I hope this helps.

i asked my mechanic to take a look at my engine mount while he had it in the shop to do my water pump. he told me it looked like it was worn and may have initial signs of cracks, but he said when he seems them "fail" he notices a clunk when he shifts or takes off from a stop...something like that... he said I had no clunking and he basically said he'd be happy to change it for me, but if it were his car, he'd probably just leave it....

my car has 75k miles. is it possible that a car with my mileage still has "good" mount or are they virtually ALL bad by my mileage???? i was under the impression that by my mileage, ikt would be toast...

my car had a new motor put in at 15k and the car has 75k...so my mount likely h as about 60k on it as he stated these get changed if the motor gets replaced...

... first, if you have an OEM mount, they only last 45,000 miles.
If your mileage is beyond that, I guarantee it is cracked.

The 987/Cayman mount is much softer than the older 986 mount. Some customers complained about the 3000 RPM vibration and Porsche removed even more material and made the material even softer. They now only last 35,000 miles.

Most people find the Enthusiast's Version their choice, even if they AX and DE.
The Racing Version I only recommend for a track car. The vibrations are very noticeable. I'd only recommend it for a dedicated track car.
The Racing version also provides less power loss to the rear wheels.
Both versions provide much better shifting.

When it's brutally cold (below 20F) the remanufactured mounts will transmit much more vibrations for the first 10 minutes or so, until the engine's temperature warms up the synthetic rubber compound and makes it more flexible. In warmer climates, it's a non issue.

The TechnoMount is supplied as a bolt-in piece, complete bracket, not just the center.

The TechnoMount will not harm the transmission mounts which are gel-filled.

Hope this helps.
If you need more info feel free to contact me.
Happy Boxstering,
Pedro

Orange gel?

I don't disagree with Pedro that there is a decent amount of vibration. In my opinion, the feedback from the motor to the seat of my pants is fine by me - one more way to detect if something is acting up and shut down before it's too late.

I have a tendency to drive in second too much instead of downshifting to first at the AX - the extra vibration at ~3200 RPM should be a great reminder to downshift and make some extra power.

Three-month followup: I decided to replace my Pedro mount with the upgraded (987) mount. The extra vibration transmitted to the cabin wasn't bad, but the effect it had throughout the cabin wasn't tolerable for long-term use. Anything that could rattle did rattle (the lenses in the map light, parts of the convertible top when it was up, the center console, etc.).

This is of course not a criticism of Pedro's product - as he's stated repeatedly, the racing mount DOES transmit more vibration to the chassis. At the track, it does a great job of anchoring the motor to the chassis. On the highway at 3,250 RPM, it does an equally stellar job... but you may find as I did that you didn't want a solid mount as bad as you thought you did.

If I blow through the 987 mount too quickly, I'll probably try a Pedro enthusiast mount, but the racing mount was a little too hardcore for me. I should have heeded Pedro's advice on his site.

All that said, it's still a great product. Thanks, Pedro!

Now that I am reading your post I've just realised why I am noticing so many more rattles in my car lately!

Yes, Pedro's racing mount is harsh around 3k rpm, and yes, everything does rattle.

I am now resigned to driving top down more often, so I don't notice the little noises so much, and just enjoy the extra tight chassis feel that I experience with the racing mount.

Pedro represented it as it is, he didn't recommend it at all for a street car, but I am quite happy trading comfort for performance.

Let us know how the 987 mount goes, I'm sure not everyone is as crazy as me and would prefer a little more comfort.

My original mount lasted 8 yrs. and 60k miles, at which point I then started feeling grinding noises during hard cornering because the drivetrain started shifting due to the worn out mount.

I had it replaced with the 987 mount, and I like it because it got rid of an annoying driveline vibration I used to have when the car decelerated to around 3K rpms. We'll see how long it lasts, but I'd be perfectly happy replacing it again at 100k miles because I don't like vibrations trasmitting through the chassis, personally.
