Review: Worth the money - Engine runs very nice and smooth with this recommend for sure
Review: Wow what a difference. - I have a hybrid, self-built EJ Subaru motor with a lightweight flywheel and a Perrin lightweight pulley (because I liked shiny things). After replacing the Perrin with the Fluidampr, the engine feels much more stable and revs happier. Does not die and the shudders are almost completely gone! I would daily it if it wasn't a track car. Bravo! Tips: Soak in hot water for 15 minutes before installing. Torque to spec.
