TSR Performance are a authorized U.K distributor for Fluidampr products in the U.K . We hold a large range in stock and also make regular orders from the U.S . Engine harmonics are often vastly changed when they are tuned and components are replaced. The Fluidampr can be described as a self tuning device that can work in various setups to reduce harmful harmonics and vibrations. We advise these on all of our high powered engine builds.
