Exedy Cerametallic Stage II Thin Clutch -- Fits the 06+ Civic Si (K-Series) Models
EXEDY cerametallic clutches are designed to handle the abuse of high power modified engines. The cerametallic friction material can handle much more slippage than stock type disc assemblies without slipping and fading.
All EXEDY cerametallic clutch discs have spring center dampers to reduce the impact and shock loads put into the drivetrain. This protects the transmission and the rest of the drive line system.
EXEDY offer two types of cerametallic discs - normal thickness and reduced thickness. The reduced thickness (thin cerametallic) disc offer greatly reduced inertia to improve shift effects, make for faster shifting, and improve synchro durability. These discs are approximatelt 1/2 the thickness of a stock disc AND IS USED FOR TRACK ONLY.
Normal thickness (thick cerametallic) discs have better heat capacity and therefore better durability in demanding applications such as all wheel drive. Even with the normal thickness, our three puck cerametallic discs still typically have less inertia than a stock disc and IS GOOD FOR STREET AND TRACK.
With any cerametalic clutch system, there will be some compromise of start up driveability as compared to a stock clutch (chatter on light throttle, low rpm start up). This characteristic is general felt to be acceptable in modified performance cars. Drivers of cerametallic clutches on the street should be warned not to "ride the clutch" to try to reduce the chatter as this will greatly increase the wear.
