Stiffer engine mounts suck. The amount of vibration and noise resonation in the interior is unbearable. Makes the car feel like a $100 car that was just driven away from a yard sale. I feel it is the worst downgrade anyone can do to the car.

The ingalls damper is brilliant. The mounting is well thought out, no need to drill a hole in the shield. It also has a small neutral zone in the damping. This way, no vibration is felt at all. I think an ETD will serve a good purpose by taking stress of the stock mounts which commonly break after high mileage.
