I dont think Fluidamper has anything over the other fluid type dampers except another hundred bucks. They do better that the elastomeric dampers and are a captive fit so they wont tear off and go spinning out the side of your car. TCI makes a mechanical damper called the rattler. These 2 piece dampers have less rotational weight and look alot better than the iron ones. The CAT dampers and other branded dampers are almost cheaper than the correct rebuilt iron ones. Be careful if you get one for a B/RB as the flat faced ones will misalign your pulleys, look for the recessed front ones. They were a second generation design, and most dont include the bolt which I found needed to be about 1/4 inch longer as they are thicker down there.
