Thstone is correct. I had a "enthusiast" mount. Semi- solid put on after my original craped out. The vibrations, for me at least, were unbearable.
I then installed the cayman mount which as the same durometer as OEM 986, but is said to be an upgrade on longevity. Now it feels nice- like from factory.

Thanks, guys. This thread is helpful, as I plan on doing this next month. Is the 987 mount any stiffer than the 986 piece, or is is just more durable. I would like stiffer, and am willing to put up with a little bit of vibration, but not much.

987 Boxster and 987 Cayman use the same part. I could tell no difference between the 986 and 987 engine mounts in feel.
Why do you want a harder mount? Are you drag racing the car? You can always make your own mount, it's not hard.

Just for a more firm feel. I track the car a bit, and performance is a bigger priority than comfort.

Be careful. The more solid mounts can trigger the knock sensor.

I just had mine replaced with OEM 987 from a factory 986 for a 2001 boxster and man alive what a difference!! I think it is a great combination of comfort and rigidity. From what I got from it. I only drove it about 10 blocks due a license discrepancy  .
So far so good tho. I would recommend the OEM.
Also I don't track the car so I can't speak to that. But for street, she's a beaut!

... right!
Many people that have made their own or purchased a very rigid mount could end up loosing power,
The knock sensors on the engine are actually vibration sensors.
Sometimes with certain mounts the harmonics created can mimic knocking and the DME retards the timing, cutting back power.
Happy Boxstering,
Pedro
