Revshift 80A Motor Mount Review, 80A transmission mount review

Hey guys, i have a question about cabin vibration. Background, 2007 e90 335i with 80K miles on it, was running FBO with Motive Flex fuel MHD stage 2+,( with quiet start option)
Just recently i did a spool overdrive kit, Pure600 turbos, outlets( inlets were already in), New engine mounts from Ecs ( Density Line Performance Motor Mount Set) as well as Density Line Performance Transmission Mount Set, and Spec Stage 3+ Clutch kit with Steel SMFW kit from top gear solutions. Im having a couple issues, I did get tune from Wedge for this but couldn't do a hard log as the clutch still is new,.. Also to note, i had to install the TOB on the high side( the low side of the TOB) wouldn't allow me to go in gear, and when trying to put the car in gear, the wheels would start to spin on the lift, but not allow me to go in the actual gear.
Issues im having
1. Not all the time, but on occasion, there is a delayed crank when starting, the car.( HPFP has been updated twice with 2nd gen) never had issues with start until now after all the work
2. Im having a vibration( feels like under my seat or mid arm rest) almost like going over a very minimal rumble strip), in low rpm(1-2k), low gear, and low speeds, smooths out with throttle( I sent in a few logs to Ken, and said there nothing with the tune issues)
Ken mentioned the car can drive like crap with different trans mounts.... any help, appreciate it.

Ok. Sounds good. No thanks. Just wondering if people had this issue. Appreciate it
I mean, sounds like you're using virtually solid engine/trans mounts and are surprised you're experiencing NVH. NVH is bad if you go solid on both esp with single mass...
Sorry if that wasn't clear before when I suggested you change your trans mounts.

Sorry that was a typo when I said " no thanks". The reviews were good and no one mentioned any vibration. Appreciate your recommendation!
He's right. RE is the way to go. Rubber is the solution. I run the RE mounts with AKG cups. Best of all worlds.

Any car I get immediately gets upgraded with RE trans mounts. I am actually making a video soon on e46 manual trans upgrading with RE trans mounts.

This gives you the NVH isolation rubber can provide, with a way more beefy rubber mount (not even comparable to stock), and the cup provides some deflection insurance, if that's a concern.
