Poly motor mounts?
Can anyone suggest a good new motor mount that I should get for my 93 GT? I think that's it's time to replace mine.
What brands are the best for motor mounts, or are they pretty generic and should I just go with Mac or some ebay brand or put out a little more and notice a difference? Also, how long do urethane mounts last on average?

RE: Poly motor mounts?
energy suspension.
why do you think it will break something if you use both poly engine mounts and tranny mounts?
I have had mine on there for a couple of years, and nothing has broke yet.
and they will outlast the rest of the car.

RE: Poly motor mounts?
sorry for the vauge "break stuff" statement.
My buddy ran poly mounts for the engine and trans with a tremec 3550. this was a drag racing application also. he ended up breaking the tremec 3 different times. the OEM bushings let the trans and engine have a little bit of give under high loads, the poly bushings dont. so the weakest driveline link ends up breaking. this case being the input and output shafts on a tremec 3550.
if you arent racing and launching at like 4500+ then you'll probably be fine. In my opinion, i wouldnt reccomend using a poly trans mount. OEM should be fine.
