I have a friend with a boosted p5 that broke a couple of his mounts at the track and now he is back on stock mounts. Here is a pic of my pass. mount. It took me a few minutes comparing mine and yours to see what you were talking about.
AWR is a stand up company, I had a of set rear sway bar links for over 3yrs that were the wrong size. I called Tony up and he said not a problem with doing an exchange, keep us updated I looking to by the side mounts from AWR.
engine jolting back and fort from not having solids in front and rear of it will be your best bet of pass. mm failure
edit: options would be solids front and rear mm's and get a replacement from AWR or solid front and stock + inserts rear mm and get replacement from AWR or go with stock + inserts pass. mm.
