So I have 75a durometer mounts in my eg civic, but the car rattles too much in the cabin. I want to daily the car but I hate how much everything shakes. Are there any OEM replacement mounts that would fit the engine and chassis? I don't wanna have to fork out $300 for some 60a hasport mounts that might not even fix the vibrations.

 

Integra mounts….the ones that came with the swap

 

So what u are saying is OEM integra mounts?

 

Yes, Integra mounts. If you don't want to modify the frame rails, you should use the Left, Rear, and Right Upper trans mounts from a '94-01 Integra; the Integra Front Right torque mount bracket combined with the Civic torque mount itself; and lastly, the Left side Civic torque mount with the A/C bracket of your choice. If you want to use ALL FIVE Integra mounts, then you must remove the mount locator plates on the underside of each frame rail so that the Integra torque mounts can fit flush against the bottom of the frame rails. The locator plates are spot-welded on and must be drilled out and knocked off the frame rails.

 

60A/62A/etc mounts would totally get rid of the obnoxious vibrations. 75A are trash for street car builds.

When swapping my engine over the winter, I found that that the urethane in my Innovative mounts had deteriorated. They honored their lifetime warranty and offered me an "upgrade" to the 75A urethane. I went for it since I expect the new build to be around the advertised whp limit for the 60As. Totally regret it, and I'm going back to the 60As when the temporary engine gets swapped back out (or maybe switching to Hasport). The mounts were installed per the torque sequence in the HELM manual and were properly lubed with Energy Suspension silicone grease.

All of the builds we do at work use 62A Hasport mounts, and urethane durability is never the problem, even at elevated power levels. Granted, we are building road race cars and so not making extreme power and they aren't subject to launches/standing starts. They also rattle and buzz less far less than my street car with 75As in it... by a good amount. You can hold a totally normal conversation in the car at idle and driving around at road car speeds. Meanwhile, the 75As in my 2000 sedan are rattling the car to the point where I occasionally find nuts/fasteners on the floor and have to get up under the dash to figure out where they came from and re-attach. Granted it's a 25 year old 300k mile street car but man, what a nightmare it's been.
