HIGHFLOW LINEAR PISTON DESCRIPTION
Each piston face has a dished surface, to preload the valve shims flat against the piston face. The HighFlow piston ports are larger and allow for roughly 50% more flow. The result is a more compliant feel which typically gives more mechanical grip but less support. The standard dishing is 1° on both the compression and rebound sides of the piston. By increasing the compression side dishing to 2°, the shims become increasingly preloaded, causing a slight delay in opening during compression movement. The dishing causes the shims to “snap” open, in return giving the car a “snappier” feel as opposed to a smooth roll, once again this modification is for driver feel.
