Which tranny mount?
I'll looking to reduce some of the movement in the Z's tranny. (M6) I've found 2 different mounts.
1)
2)
Is #2 any better at reducing movement while keeping vibs to a min? Enough to justify twice the cost of #1? Just getting sick of how noisy the tranny is when first getting going with a new gear. Seems like it must be moving way too much. 80k on the clock.
Also considering a tranny/diff brace like this to hopefully prevent any tranny damage while drag racing. Thought?:

I have a Pfadt mount and it has done very well and to me seems like it would work better than the first just because it distributes the load across a greater area. The brace would also be a good idea if you are planning on doing a lot of drag racing as well.

One thing I wonder about the brace is does it actually even do anything? Doesn't the case usualy brake because of the extreme twisting force inside? The trans/diff braces don't look like the would stop any twisting at all just looking that their design...
What would be better for a little more insurance against breakage, the brace or the mount? I kind of thionk the mount may make it easier to break the trans.

I have the Pfadt mount. It works well and for me made a clear difference in the drive train movement. Also in the handling of the car. It really keeps everything in place. Having that long trans mount is like having another sway bar in the rear. So much less role and movement of the heavy parts back there.
You will not reduce any noise or vibration with it! It does in fact amplify noise and vibration. The stock rubber mount and damper weight on the side do good for soaking it up. But it is not bad at all.
Remember the mount and the brace serve different purposes. The hard mounts stop movement, and reduce wheel hop. The brace reduces stress on the transmission and diff and takes allot of the beating to avoid cracked cases. Both are ideal.

The Tranny/Diff brace will keep any breakage to a minimum.
It helps eliminate the twisting of the two units.
The Trans brace, from what I have read here on the forum.... is an increase in vibration/noise.

How does the brace stop twisting of the case at all? Looking at the design of it, it looks like twisting is the only thing the brace would let it do. Now if everything was welded solid, it would make sense that it would stop twisting but doesn't look like it would with the fittings they use on the cross brace bars.

Its the mount that stops twisting. It is easy for the stock rubber mount to allow the drive train to twist and rock around. The Pfadt mount plants it down solid and does not allow side to side movement. The brace helps with structural integrity of both the tranny and diff.
