Pendulum mount needed with upgraded motor mounts?

Car is at 65K with a hybrid is38 and pretty sure my trans mount is torched, so I've settled on doing the 034 density mounts for both the engine and trans.

Question is will this affect the dogbone mount, I've heard horror stories of people having stock ones snap. Though I can't tell if this due to upgrading motor mounts or not.

I'd much rather pay 200 to put in an aftermarket one rather than f**k up other stuff, but would prefer to stay stock to keep nvh down if its not going to make much of a difference.

The dogbone mount is very important. It's what stops the driveline from rotating front to back. All of the dogbone upgrades will produce more NVH, some more than others.

Would I be better off with a whole new dogbone such as the 034 one, or just an upgraded puck like the powerflex one

Damn so many options now, thinking about just doing the full revo or ecs kit. Anyone have any experience with the ecs kit. Both seem to be the same price but ecs comes with a whole new dogbone.

edit - Also looking at the BFI kit but I don't like how their insert only seems to be a lower compared the full revo or ecs

As someone that has had the 034 engine and trans mounts and now the BFI eng/trans mounts I just want to suggest that you save yourself the time and money and just go with BFI mounts from the get go. There is a thread where I and quite a few others has issues with our 034 mounts, you can check it out below.

Yea that's not the only thread I've seen about 034 failures now...
As far as I can tell they're using cheap factory cast frames and just replacing the bushing.

Also from an engineering standpoint that I can 100% see how that roc euro arms cracked a transcase. Solid arm with no bushings/bearings + compliant eng/trans mounts = a ton of stress on the housing

I'm now down to either BFI trans/motor with Revo insert, or full Revo

I had the old version of the Revo set on my old '16 GTI. That version had the black rubber instead of the revised red rubber/poly that they have now. They wore out quickly, wouldn't recommend. Plus their customer service is unresponsive at best.

BFI mounts are great, I have a set of the Stage 2 on my '19 GTI. Also have the 034 dogbone arm with both the upper and lower inserts. Tons of NVH with this setup, but drivetrain movement is very limited.

If NVH is a concern, get the BFI Stage 1 mounts with either both 034 inserts, or a poly insert.

Yea went with a BFI stage 1 motor and tranny mount, and a powerflex hybrid insert. IMO I didn't like how the revo mount didn't have that ear that bolts to the side, while oem and every other aftermarket one did.

I'll report back when they come in on how this setup feels on nvh and engine movement.

Installed both BFI stage 1 motor and trans mounts after christmas. Worth every penny. I also have the apr pendulum mount. Like others have stated, NVH is noticeable when taking off from first and in reverse.

Well for about the past 10k miles I've had issues with the downpipe rubbing against the chassis while wot, took me a while to put two and two together. Any nvh has to be better than that lol
