Right now the MPS in my car is mounted with some sheet metal screws and old squished rubber grommets. Not at all the original mountings... Didn't see any suppliers for OE-style replacements anywhere near here, so I am looking at re-mounting it on some rubber standoffs like this:
 10mm in diameter, 10mm high, M4 threaded studs (Form "SS"). Three different Shore A hardnesses available, 40, 55 and 70. The same ones without the "necking down" in the middle are also possible:  The idea is to mount the standoffs to the body sheet metal and then be able to easily bolt/unbolt the MPS on the protruding studs with M4 locknuts and flat washers. What do you think? The mounting should be soft enough to damp out vibration but not so soft to allow the thing to shake significantly. |

I was also working from home and got this back from my local Porsche dealer concerning the grommets:
I am following up on a request for x4 of P/N: 113-957-855. Total cost before taxes for these parts will be $57.48. That's a NO. |
