Anyone on Upgraded Trans Mounts?

Obviously for us 3 pedal folks...
Anyone running poly (or solid) trans mounts on stock engine mounts?

Im worried if I dont upgrade the engine mounts also the stiffer trans mounts will fail sooner. I know this was an E30 problem but making things fully poly on a rust box E30 made more sense than this nicer DD now.

Also how was the NVH afterwards?

I want to upgrade because Im starting to miss gear gates when the car weight transitions in autocross/canyon runs etc.

I'm actually 8AT .. but was just looking for the same .. found some solid metal from the UK I think but went with OEM to replace.. I had Delrin solid in the diff and changed them out for super pro .. as the NVH was pretty noticeable.. so I would imagine solid on the tranny would be loud too.. though I ran solid metal back in the day on my M3 E36.. Let us know what you find ..!

I would say go with the 70A durometer poly mounts. These worked well on my E36 M3. I think 80A or solid would just be way too harsh for anything other than a dedicated track car.

Those are the exact ones I was eyeing.

Jared, did you upgrade motor mounts too on your E36 or was it only trans? If so how long did the trans mount last?

Just trans mounts as the stock mounts were pretty worn and there were all these horror stories of money shifts due to tranny moving durning high G maneuvers. They lasted until I wrecked the car (RIP Emmy), about a yr. If you go with 70A poly mounts please post a review here. This is something I would consider doing as my plan for this car is to be a track rat after I pick up another DD.
