just went back a page and read what BFI said bout the break in. but from a users vieepoint @1500 miles. elaborate on "bliss"

The vibration from the mounts is nothing to worry about, the insert however, take your time installing that. I had mine out once to try the 034 last week, the second time I reinstalled the BFI insert must have gone better, because the vibration was half as bad as the first install. I used thick silicon paste grease second time around, only thing I did different. 90% of the NVH is caused by the inserts.
If you're getting just the BFI mounts though, the vibration(IMO) is perfect feedback from the drivetain. You can also hear the timing assembly on cold start-up, and the backlash in your trans gears, two things I like
It reminds me I have a performance car, not just a golf that comes with old women mounts and an evil device called a "turbo silencer". It sucks we have to unwrap our cars so to speak. At least that's how I feel.
Bliss, meaning it accomplished exactly what I wanted to accomplish, and then some. The drivetain doesn't flop around during aggresive driving anymore, and the TSC light comes on a tad less frequently I feel. TBH if my Clubsport S muffler wasn't already ordered at the time, I probably wouldn't have even bothered, the engine noise transfer through the mounts is almost like getting an exhaust.
Torque specs for the larger bolts(18mm socket head) is 60NM+90 degrees, the smaller bolts are 40MN+90 degrees, and the small horizontally mounted bolt on the upper engine mount is 20NM+90 degrees. You might not get the 90 degrees if you are reuising the OE bolts, as these are torque to yield and probably won't stretch that much again. I gave them a +45 degree instead. I rechecked the upper engine mount a week later and nothing had loosened up. I would like to double check the trans mount but as you'll see that is slightly less convenient to check. I used and engine hoist and the hooks by the fuel rails. Good luck!
