Fastscions has an engine torque damper. Ingalls Engineering "Stiffy" Engine Torque Damper: Scion xA / xB 2004 - 2006
I'd be inclined to do the motor mounts first.
Great info, thanks a lot guys!!!I have the Ingalls torque damper, the engine doesn't shake but some parts of the body frame make the rattle occasionally, either the dash inside and the exhaust, my exhaust rattle above the rear sway area hitting the body frame, I fix this by securing it down.
but having the torque damper feels more grip. BTW, if ever you're goin to put this, make sure you have a jack under the engine, after I removed the engine mount, the engine lean forward to the right.
