Anyone running Ecs 70a trans mounts on the zf8? Getting ready to do new engine mounts with vtt plates, and throwing around the idea of upgrading the trans mounts, drivetrain play is creeping in on stock mounts.
Plan to go solid subframe mounts soon and a diff lock down plate from BMS but would like to start with engine and trans. Anyone? |

Are you using your car on the track ofen Pussiwillow ?
solid sub frame mounts introduce a wide range of diff noises inside the car. Urethane mounts aren't too bad but sometimes they fail.

I'm not around the car right now, I have mhd but never looked to see if it was doable there, google didn't bring much up; I'll check things later if I end up needing to, maybe through inpa.

I had an e36 I built from the ground up, full suspension and chassis, engine build and swap, etc etc, sort of longing for the planted feel again, this car is wayyyy too plush and floaty for what I want, it's my third car I got to have fun with. Solid subframe and 95a diff mounts were what I used in the e36 and it was perfect, 95 a engine and trans mount with chassis mount shifter, I'm used to a little more NVH than the average LOL |

UPDATE:
Mounts are in They don't vibrate much at idle, you can hear ever so slight rattle, very faint; but when you drive you can hear the transmission doing transmission things, as well as ALOT more engine noise in the cabin, this is my project high performance street car and this thing feels light years better on and off the throttle, pretty noisy but I feel it's worth it; comfort mode isn't bad at all |

Damn. Well that's probably it for me then. I might just try a new set of stock mounts or see how 034 does with their rubber ones.

I think they're a 55a rubber bushing Very good mount; I dunno if they list fitment as f3x but they're all the same at this point and would work fine having seen the mounts; I ran them in my e36, rubber version of what I put in last night Wife hasn't been in the car yet, she's probably gonna say something so I may swap to rogue if she complains too much, I hate when my dishwasher makes a whining noise ... |

Get a vid of the current noises if you can, I'm kinda curious. Is it just straight cut gear noises?

Here's the rogue mounts for anyone interested, i may grab these just to try them and review it for y'all, I may run cups on them as well; I'm gonna run the Ecs for awhile first

Update
Diff brace definitely tightens the rear up, it doesn't feel "swimmy" on the throttle very minimal noise and really no extra vibrations must a lot more planted I guess, another update, the trans mounts are amazing but annoyingly too stiff for commuting on highway, a lot of harmonics between 2-3k rpm unless you're really in the throttle, I ordered e21 mounts with aluminum cups from Akg to try. Solid rubber with deflection cups. https://www.akgmotorsport.com/produc...e92-e93-z3-z4/ |

They're in, they require modification to fit, the studs require 1mm approx drilling of the lower trans cross member as well as removing the alignment pins and filing 1mm approx of the upper trans bracket forks.
Rogue mounts you do not need to. Something to consider, however e21 mounts are beefier, and easily replaceable at a lower cost, either way, on to the good. So these are much more planted than stock, they definitely feel sturdy and solid under load, side to side on and off the throttle. Hardly any vibrations with the cups, I would say 80% as solid atleast, as the poly mounts with 10% -15% of the NVH. Anyone could jump in the car and never notice NVH or comment on it, feels really nice when you get on the throttle, keeps things planted, this is 110% what I was looking for and more than pleased with yet another AKG product. |

To add
You can buy rogue mounts, I don't think they require any type of modification since they run stock sized studs, and I believe they have the alignment notch in them already, you can buy akg cups and fit them on I believe, I didn't want to mess with it, I like the larger studs and the cup made for the e21 mounts as a package deal, honestly so pleased with this, wife said the car feels perfect, dishwasher approved! |
