I have a 1996 civic hatch with a gsr swap and it came with a full set of innovative motor mounts installed but since its a daily driver, the vibrations are starting to get to me. I was wondering if it's a good idea to replace the rear t bracket mount with an oem one to reduce the vibrations and keeping the side mounts poly as a middle ground between the soft stock mounts and stiffer aftermarket ones. I read somewhere that the rear mount really does most of the work so I'm not sure if I should just replace all the mounts with oem at that point.

 

anyone done this before?

 

The mount can absolutely be replaced with a factory piece.

The rear bushing is the same for 96-00 civics.

 

How much more will it make the engine rock back and forth? Should I reinstall the front engine mounts?

 

that part i can't answer. However, if you are going to go back to factory rubber bushings, I would recommend putting the front torque mounts back in. those could help with some vibrations, if you have them already maybe put those in before swapping the rear mount and see what happens?

 

Sometimes the vibrations will go away with time not all the way but noticeably. If you go back to stock just know your losing all benefits of solid mounts.

Just taking out the rear will get rid of some but not all of the vibrations

 

The car never came with the front torque mounts so I can't really do that but wouldn't adding more mounts cause more vibration?

The mounts aren't new so it's definitely already fully broken in at this point. I mainly just don't want my side and rearview mirrors vibrating so much to the point where it's hard to see clearly out of and a lot of my friends who aren't really car enthusiasts are hesitant to ride in my car because of the vibrations.

 

I doubt it. If the vibrations are that bad, I would suspect the mounts are either shot, or a high durometer.

I have innovative 62A's in my b swapped civic and I don't notice much vibration, especially to what you're describing.

 

I was thinking that might be the case but the mounts are pretty worn so I can't tell if they're the red 60a or black 75a. Do you get no mirror vibrations at all?

 

Not at all.

I'll get the occasional dash noise, but it's a 24 year old Honda, so I do expect certain things.
