Thanks. I'll assume they're the 60 then since all documentation from when I bought them said they were 60A. I didn't realize there were two red bushing options. My old bushings were blown and these Innovative mounts were an affordable upgrade; I've been very happy with them.

 

I think I'll try the 75a transmission mount

 

Still looking for input on what diff mount bushings to run on my 8.8 kit.

Leaning towards 85 or 95a

 

85 is very stiff. 95a would be like solid mounted. I say if u drive ur car on street 85 is more than enough

 

Would stiffer transmission mounts even cause more vibration? Doesnt most of the vibration come from stiffening up the two front motor mounts?
Also when i had some aftermarket metal collars installed into my oe diff mounts, felt absolutely no different from stock mounts without the collars...in terms of vibration/sound.

 

Lots of vibrations comes from the tranny. Most of it is from the motor but yes the tranny does Vibrate and it's the most noticeable as its right next to the legs.

 

I just decided to go 95a. I will post a review when I get some drive time.

 

Did you go 95 for trans mount? What about motor and diff? Keep us updated

 

Running 75a all around. Engine vibration I'm fine with. Feels like a race car. My problem is the noise transmitted through the chassis. Long road trips are a pain. Makes hearing any song a hassle since your trying to over power the engine/road noise.

 

I intalled the Hasport 62A diff mounts yesterday and gave them a good drive out today. My OEM mounts were still good after 90.000km but didn't like the softness especialy during hard acceleration and downshifting.
The Hasport mounts changed that in a positive way an made the rear more direct. No increased vibration or what so ever which i kinda expected, since the engine and gearbox are more known for causing this.
What changed is the sound of the diff. It's overall a little louder compared to OEM but really nothing to worry about. You can listen to music and have a conversation just like before . The typical diff whine noise is also slightly higher pitched - which I like - and is not annoying. It's only happening in certain situations just like with OEM.

Now I'm thinking of replacing the engine and gearbox mounts too, but can't decide with which brand to go.
Should I go with Hasport's 62A engine mounts or with the Mugen/Spoon mounts which are around 70A?
Are the Mugen and Spoon mounts identical besides the reinforced gearbox bracket supplied by Spoon (which I doubt it's doing much tbh)?

So far I only heard mixed review of engine mounts like the Hasport and Innovate. But then again, people went straight from a 50-55A OEM to a 75A or higher durometer and complain about cabin rattle and vibration.
