Any one else use them? my oem engine mounts are shot and tempted to go solid as the price is 1/2 of what the OEM replacements would be only they need to come from America. Polys are also an option though crazy expensive.

Its only the weekend car so i'm not worried about loosing to much comfort.
 
What car is it?

Expect the vibrations to be horrible, might find the gearshift tightens up a bit though.
 
Ive had polybush engine mounts on my last 2 cars and they were great. The car felt so tight as did gear shifts etc.

There's more noise and vibration. I wouldn't go completely solid though. I picked uo my bushes fairly cheaply one set from the USA and one used set from an owners club.
 
i bought a solid front engine mount and it drove me mad within a matter of days

turns out a new rubber one is 10x stiffer than a 10 year old rubber one anyway

Thats another reason I'm looking at solids, the gearbox is crunchy as it is and any relief on that is a bonus!

Car is a GTO 3l tt V6. some of my thinking is as its a V6 the vibrations shouldn't be as noticeable as say on a 4pot.

Poly bushes would work out to be around the £4-500 mark once you factor in shipping and vat ect, the solids are £200 and i can get an unused 2nd hand set of oem's for £200.
Polys would be my preference but cant justify spending that much on a car i use half a dozen times a month or so.
 
There are solid engine mounts on the Firebird, and boy can you feel (and hear!) the vibrations from the 6.6 litre V8! Together with the noise you would never be able hear a stereo in the car!

If you dont need them for rigidty reasons I'd get normal mounts I think.

Is the car heavily modified? See a lot of track work ?

If not stick with the OEMs.

Mildly, will be running 400-450 bhp in the coming months. No track mind, maybe a few runs up the strip. The issues are the transfer boxes are prone to breaking on these so any help to alleviate that is no bad thing.

Imo oe bushes then, put the rest into some new gearbox oil.

Already tried new oil, the gearbox is shafted, just waiting for it to completely die to replace it but its being stubborn.

Seems the majority are for OEM :p sensible head also agrees but where's the sense of adventure :D
 
Solid mounts are ridiculous unless it's purely a competition car, and even then they have downsides.

The vibration and noise will be awful, and cracking around the mounting points is not uncommon.
 
Everyone will have their own opinion on what is an acceptable amount of vibration so unless you can have a ride in a car with solid or poly mounts you really won't know if you like it until they are fitted.

From my limited experience I enjoy driving FWD cars with stiff engine mounts, the gear change and throttle feel much more precise.
