I broke a CV the other day and I'm considering a solid trans mount to keep that from happening again. I know I'll get the gear noise goin on, I can deal with that. But would it affect the ride quality in any way?

Semi solid is better, I swapped my solid out for semi solid... and wish I had stuck to the semi solid all along!

There are options!

so this one is no good?

For a track car sure its great... for a street car, semi solid will yield all the stability the solid offeres, with a quarter of the noise!

Damn, you almost made throw it away with this, this and this

Where can I find some semi-solid mount options?

Lindsey has one

Or you can DIY it by filling the mount with polyurethane resin. Look it up, I did it on my car and couldn't be happier.

+1^ Get some 3-M Window Weld, do a search on this forum, and you'll be set.

Make sure your mount is in okay shape before filling with window weld. My stock mount on my car was a little rough. Someone gave me a good used unit. I filled it with window weld. The mount is much stiffer now. I have no noise whatsoever, and the best part is that since I didn't fill my entire mount/crossmember with the resin I can still change it out and get a new mount if I ever need/want to.

EDIT: Orielly auto parts carry's window weld for $20 a tube. Pretty cheap upgrade if you ask me.

Bah, the solid was absolutely fine in my street car. If you can live with the noise you will be fine.
That cross member has a fair bit of flex and will still allow more movement than you think.

I am running the LR mount on my car. Expect some extra vibration and a fair amount of extra noise, mostly on decel in gear. I cant even imagine how loud the solid mount would be.

I'd imagine that a semi or even just a new stock mount in addition to one of the braces that have featured on here many times would be perfect for street or semi track car?

The solid mount does add some noise and vibration inside the car. Since mine is a track car I live with it. As far as the broken CVs go that maybe a totally different issue. The CV are use once only bolts and should be discarded after they have been removed. A lot of times I have seen them re-used, when they are you need to check the torque on them on a regular basis as they will back out which puts an undue strain on the CV.

Solid is overkill in my opinion, and risks other issues. The whole driveline is a 3 point mount, the two front engine mounts and the rear transmission mount. There needs to be some compliance (again in my opinion). Filling the mount using the various methods is the way to go.

Stock mount, even when new is too soft, for agressive use.
