bad motor mounts

**silverz28camaro** · 11-02-2006, 10:43 AM

left side mount is collapsed and rear trannt monut is broken

thinking about getting solid motor mounts? good idea? anyone try them?

and the tranny mount i was gonna go with a high quality urethane mount

i noticed this when i put on my headers and the off road y-pipe was hitting the floor pan, looked underneath and sure enough the motor is tilted........................NOT GOOD

Cet the Poly mounts all the way around you won't be disappointed.

Get the Poly from Thunderracing.

I agree with all the prior, do not get solid motor mounts just get the poly ones for all. If you want solid mounts for your motor, try sitting on the motor while it's running and if all the vibration does not bother you then you might get them but they transfer ALL of the motor vibration

to the car. Of course I am kidding

...about sitting on the motor that is but for a driven car and not race only I would not recommend solid motor mounts.

cant seen to find polyurethane mounts for my 2000 ls1, even at thunder racing all they have is the plate or solid mount,

a buddy of mine has solid mounts on his 53 chevy with a 350 with 12.1 compression, cam, and it revs to 7 grand, yeah it does shake but not too bad, he said there wasn't much diff between the rubber and solid

now on an ls1 fuel injected motor that already runs pretty smooth i don't think it would be as bad right?

besides i have a shift kit that chirps tires at part throttle so i don't think a little vibration is gonna bother me,

its not a cadillac, and im not george bush,

Trust me the urethane ones are just fine. They give alittle and that is what you want, besides the solid ones are probably harder to install.
I got mine from Detroit Speed Shop they are associated with Livernois motorsports.

My suggestion to anyone would be to have your motor mounts checked; especially if you have a high HP engine. Found out that my block had a crack in it. Eventually I was shown it was due to a bad motor mount. Fortunately for me, the guys at the dealership were able to determine that my engine is not abused; the engine is in pristine condition. Otherwise, I would have been ass'd-out the $4-5K it would have cost to get a replacement engine; I was charged only the deductable. Check your motor mounts!
