Competition Clutch Stage 4 Clutch Kit 06-11 Honda Civic Si
The Stage 4 competition clutch for the 2006-2011 Honda Civic Si K-Series is an excellent kit and handling a pretty serious amount of power via its 6 puck clutch. The large amount of pucks help reduce the harshness of your typical 3-4 puck clutch systems. This also gives more material and longevity. With a 250% increase over stock, this puts you at about 500hp from the stock 200hp range. As with most race puck clutches, expect engagement to be aggressive, with more race like attributes over the soft cushy and easy oem clutch. Lifetime will also be less as well. This is a clutch for those who have a lot of power and have surpassed the limits of the oem clutch.
"The stage 4 clutch from competition clutch has been well used and recommended for high power 8th Gen Civic Si's, we suggest pairing it with the 2-800-ST flywheel for maximum performance" -- HARDmotion Team
