I am looking to have a pretty solid driveline when i am done. The motor mounts, trans mount, and subframe bushings should keep my carp nice and firm. I will let everyone know how they feel as I install them one by one. I do agree with Beav that the trans mount allows for a great deal of movement but I know or a fact that you will lose a good deal of luxury when converting to a harder mount, just be ready for that...

I've got the Group N motor and tranny mounts, and there is still a fair amount of slop in the drivetrain of my car. Maybe its not as much as with the SVX motor mounts, but its still enough that I have to be very smooth on the throttle in low gears to keep the car from bucking back and forth. The pitch stopper is properly installed, and the rear x-member seems to be plenty stout, so there has to be something else that adds a lot of slop. My thought is that its the rear subframe. There's actually two sets of bushings on the rear subframe. svxfiles addressed one set, but there is another set further up that appears to have even more free play.

I was very surprised at how little vibration the Group N motor and tranny mounts transmit to the car. There is barely any more vibration than with the OEM SVX mounts.
