Building solid motor mounts
 

Has anyone ever built a solid set of motor mounts to bolt on car will be drivin on a rough dirt track at high speeds and rubbin is racin in these races was curious if it would be more likely to break something thanks

I have with my OEM 2002's mounts. I didn't quite fabricate my own mounts, but I modded my OEM mounts to be solid poly mounts instead of more flexible rubber

I didn't feel like shelling out the dough for replacement mounts, so I bought some DevCon Flexane 80 and filled my failed front and passenger/tranny mounts. Comes in 3 hardness levels: 60, 80, and 94 (softest to hardest). On my old mounts, the bushing the bolt went through could pretty much be pulled out once not bolted in. They never failed after the fix, and I rocked those mounts for 6-7 years in (mostly) dry desert vegas heat.

Pics in that thread don't work anymore, and when I bought the stuff, it ran me $30. .

Basically, here's how I did it:
1) Pull mount out
2) Make a cardboard backer for one side of the mount (to keep poly from dripping out) and attach/seal with with tape (I used duck tape). If your mounts are busted, make sure the cardboard backing holds the bushing in place where it needs to be. If you're working with in tact mounts, just make sure the cardboard keeps urethane from flowing into that bushing.
3) Set the mount so it's level, and mix and pour the poly mix until it's flush with the non-cardboarded side. (repeat for other mounts)
4) Allow to cure for 24-48 hours. Cut off cardboard/tape backer and trim as you feel necessary with a razor blade.
5) Reinstall mounts on car.
6) Happy dance.

p.s. I think the 1lb kit was good for 2, maybe 3 mounts.
