Perhaps a shoe repair shop would have a thinner but robust material that could be used.

In your update, you said you DIY mount stops might have contributed to vibrations due to the thickness.

Your posts list your car as: 2000 base.
You list part # to be: 9A137525701 - $31.89 each On FCP Euro site, however, that part number shows compatibility with only 2005+ boxster
The part number that come up for my car (2001 986S) is 98637525501 which is a lot thinner, and cost $14.19 ea.
Is there a reason why you did the comparison with the newer part number?

I intend to just buy them, so trying to find out if I should go with the newer design or the correct older design.
