There has been a gross understatement concerning the amount of vibration that is transfered to the cabin when using polyurethane motor mounts.

i have always wondered what about the people who use that 3m injection stuff on mounts to stiffen them up? anyone ever heard of this, tried it, etc?

I used it on my 5th gen GTS.. front and rear.. it worked really well.. they are still in good condition and it didn't add much vibration at all. The only way to do it and have it work well is to clean the mounts out real well.. the rubber n what not.. then layer the 3m window weld in .. shallow layers let them cure.. just keep stacking it.. Expect your car to be down for 2 days .. best to get spare mounts. But once it's done you'll never need to worry about mounts again. -------------------- 87 4runner DLX 22re, 5spd, 4.30gr, 4" lift, 30" tires, HID w/ Projectors, 6spkr + sub, custom exhaust, 94 celica leather seats, SR5 gauge cluster and clinometer. Future engine swap... possibly a 2jzge.

Chris D started a nice thread about the different options for materials for home made mounts. I used the liquid stuff mentioned in the thread - I forget the name of it right now and my mounts turned out great. I did not take the original rubber out but simply added the urethane to the existing mount. My theory for this was that I wanted a mount that had a shore hardness of about A75 to A80 and the material I purchased only came in A90. So, by leaving the stock rubber in there, I was able to effectively reduce the hardness of the entire mount. In my opinion, Kirk's inserts would save some time and hassel and you would probably never have to worry about them wearing. Most "home options" will wear at some point. However, it sounds like they are probably a little hard for most daily drivers.

They're A LOT different than the kirk 2 piece inserts .. -------------------- Past: V6 Swapped 6G Celica, E46 BMW M3, Jeep Wrangler TJ
