The FX400 System uses the Power Plus I Pressure Plate with a custom, extremely durable, Sprung Ceramic disc. This is the ultimate extreme duty street and/or road/drag racing system. It is available in a 6 or 8 ceramic puck configuration, with the 6-puck being the more aggressive setup and 8-puck being the less aggressive (please specify which type you prefer). The sprung hub design allows for moderate dampening in high-torque applications, rendering it much more street friendly than solid or rigid designs. This disc is designed for outstanding holding capacity, and rapid heat dissipation. The FX400/HDCL ceramic full disc design creates a quick and rapid engagement while still creating minimal chatter due to the marcel cushion between the disc linings, this disc is designed for street driven vehicles.
