My guess is that its there to dampen a specific harmonic vibration. I have found this to be the case with most counter weights like this.

I think I need a larger damper now! Just installed the headers with Sector111 Sport Inserts and the car just idling now is ridiculous! I sure hope the vibrations are dampened once I bolt the rest of the muffler/cat together. Right now the header is just dangling basically.

You wont be able to get rid of those vibrations with a larger damper in that same location. Alot of engineering goes into the size and placement.

No doubt, I was just more curious if that was the reason. I think I will remove the front manly mount to see how much that calms down the vibrations. Does anyone make full rubber engine mounts rather than the manly mounts that might be slightly less stiff but still stiffer than stock?

Thanks, but how does the "60A Street (Red)" compare to the stiffness of the manly mount inserts? Is it softer or harder? All urethane mounts I have used in the past are always stiffer than rubber.
