Thanks for the super fast shipping. The mount got to Arizona before I did.

I would advise you only use this with stiffer motor mounts. All three mounts should work in harmony so that stresses are even distributed. Stiffening one mount while the other two are sloppy will put a great deal of additional stress on the single stiff mount. I made my own three piece setup I did notice some minor increase in NVH for the first day after that I simply didn't notice it any more.

Boomba,

Did ya'll test any other bushing options before settling on delrin? I'm curious to know if a softer poly bushing would work in place or if it would simply be too soft and not last.

Here is my review for the Boomba Transmission Mount.

The install was super easy once start. I believe I spent more time getting the car up on jacks rather than on the install of the mount itself.

After getting the front half of the car on jacks and then putting putting a jack under the transmission it was a simple matter. 2 bolts for the transmission mount to the bracket, 4 bolts for the bracket to the vehicle, then 3 bolts for the mount to the transmission. Super simple. Removed all the bolts then hand tightened the 3 stock bolts for the Boomba mount to the transmission (as per provided instructions). Next I added the bracket back in place and used the 2 provided allen bolts to hand tighten the Boomba mount to the bracket. Then hand tightened the 4 stock bolts for the bracket to the vehicle, used a ratchet to tighten everything down and done. In all probably took 15 to 20 minutes to get everything on.

Now on actually performance.

Immediately took my car out for a test drive and noticed several things.

1). Shifting performance increased noticeably. Every shift felt crisper and removed some of the slop when going from 1st to 2nd. I was able to shift faster because I was more confident in the shift actually going into place.

2). The noise inside my cabin was increased significantly. You can hear everything the transmission is doing from changing gears to engaging the clutch. You will hear every clunk and thud that the transmission makes. I have a video uploaded however it is done with my phone so the quality is lacking however you can hear some of the noises I am talking about. In the video it sounds like I am running an aftermarket exhaust but my vehicle is Stock that is the transmission mount making the noise. There was also an increase in vibration from having the mount installed which can be felt when accelerating and shifting and this isn't just at the shifter. My passengers in the back seat felt the vibrations from the transmission through the floor.



Impressions
While the shifting was improved and I loved the way it felt, the noise and vibrations generated in the cabin killed it for me. I daily drive my mustang and I would not be able to put up with all of the extra sensory inputs. I put about 100 miles on the mount hoping for things to settle into place but it nothing improved. After those 100 miles I switched back to stock so that I can drive my car without all of the noise and vibrations. So take that as you will just my 2 cents.

Very nice piece, personally I am trying to stay away from the NVH but this is very nice. Buyers should pair this with differential bushings/inserts and motor mounts.

I have motor mounts, full IRS bushings, a MGW, and a host of chassis bracing. I'll be pairing this with those, but I'm also dynamatting the entire interior. I'll provide a before and after review of the mount pre and post sound deadening.
