      The fluid is not for supporting weight it is for damping. I think what you are seeing is the mounts "sag" due to permanent deflection in the rubber. That forces the fluid against the thin rubber seal at the botom eventualy splitting it.

      Density line mounts suck. i've seen tons of failures on those things. many cars not even big turbos

Also some of the highest forces are horizontal due to torque reaction and I can't see how this acomodated in the mount. If it works it works, but I just can't see how.
      Bump for answer, will need mounts soon, its either DLI Technik or BFI Stg. 1...

      I think both are good mounts that you'd be happy with

      This is a fantastic thread.

      I'm actually trying a new set of Febi OEM mounts all the way around. My mounts are currently original, broken, and have 220,000kms on them. I figure new mounts, even OEM should be night and day difference.

      I have BFI stage II mounts in my 93 Jetta ABA-T, and it's pretty harsh. I don't mind that in my second car that's built to be quick, but I wouldn't want to daily a car with stiff mounts.

      Exactly. Plus, I'm only running stage II software, and all supporting mods. That'd put me at what ... maybe 240ft-pd-tq?

      I don't see that being _hugely_ detrimental to the longevity of Febi units. I could be wrong though ...

      Just FYI, the Bfi stg 1's aren't bad at all... In case you wanna smooth up your other car.

      I think on your dd , stock mounts plus poly dogbone insert is a good setup

      I have had my DLI mounts in for over a month and have not really noticed any increase in vibration. I love them.

      I'd like to add to the FAQ that the hockey puck idea seemed really good. so I tried it.

      the hole I made was slightly bigger than 1.5"-- for an interference fit

      got it pretty damn close


      really psyched to try it out!

      I have had the hockey puck in mine for almost 2 years now, and still going strong

      Table vise. drill press. lube.

      I just used a hole saw to cut the center out. 1.5" was too small to fit inside the bone without play.

      the hole saw has a pilot bit, which gives you the center of your hole. I pressed the cut hockey puck in with a little lube and a vice, then used a smaller hole saw for the bolt sleeve and did my best to eyeball the center. unfortunately I only had two hockey pucks - the first one was cashed out because I used 1.5" at first - so when I drilled the center too small, I had to step up the hole.

      after that I just forced the sleeve in with lube.

      pumped to hear this. was hesitant before I started, and my gut started churning halfway through. the finished product though made me feel better.

      one question though, my sleeve is SLIGHTLY off center in there, was yours dead nuts?

After a day or two I'll clean up the mount around the sides and slap it on next weekend.
      I didn't realize that the PL adhesive came in a quart size so I had to buy a bigger caulking gun. So far I'm $50 deep in this new mount.



      fti, I did this same thing on my oem audi tt mounts. They were SOOO stiff the whole car vibrated bad. it was unbearable. I then made my own BFI mount using 3m window weld and a mold I made. Even that was pretty stiff. I ended up buying the 034 street density and am really happy with them.
