Default Vibra Technics transmission brace

Hey, is there any truth to what this website says regarding the oe brace causing movement? I'm gonna change my transmission mounts as I can hear them whining a little bit but should I buy this (extremely overpriced) brace or just get some good mounts?

Looking at it, I'm very skeptical. Good mounts should do the job just fine.

Stock brace moves around?

Get some RE black rubber mounts and you'll have the perfect aggressive street setup $60

I believe the VT transmission mount also limits your header choices. Or maybe you just can't run SS V1's...I can't remember.

Rogue transmission mounts seem to be popular around here, so I'm installing them on mine.

They say that as a disclaimer but I've never heard of any fitment issues. Stash1 has the 3.5" ARH section 1 and he didn't have any issues. No reason the dual 2.5" SS shouldn't fit.

That's not what the site says.

All they claim is that the OE rubber mounts allow a lot of transmission movement, and if the mounts fail, the transmission is free to move around totally unrestrained.

Other aftermarket mounts allow less transmission movement, but they do not address what happens if the mounts fail.

The VT transmission mounts, like the VT motor mounts, even when they fail, do not allow the transmission to move around totally unrestrained.

They're basically saying that even if the rubber part of their mounts fail, the solid parts will still keep the transmission somewhat restrained.

I changed mine to Vorshlag Red. Very firm and did notice quite a lot of noise but it makes the car sound heaps better on throttle especially up high in the revs.
Total pain in the arse at idle. Shifts are much crispier tho. Can really feel the gears connecting when changing.

The stock brace is stiffer than the VT brace. That said, I'm pretty sure neither moves meaningfully. I'm pretty sure their description is saying the mounts, not the brace, are "too soft".

My SSV1s/section 1 would not clear with the vibratech trans brace.

Do you have a link to where this is identified? What tests were done on the car to determine this?

I ask because I installed the VT trans brace when I did my SMG conversion, and Id like to see the data that backs this statement up.

^ may sound like me being a d0uch canoe, but im honestly interested, and may go back to stock if the data backs it up.

What makes you believe VT when they say their brace is stiffer, and what evidence do you have to suggest that an increase in stiffness would actually have any perceptible effect? I'm not sure what evidence Ian has that the stock brace is stiffer and in what plane, etc, but IMO the burden of proof in this case lies on VT since they are the ones making the claim, not BMW.
