2013-2015 Honda Civic Si Sedan Password:JDM Dry Carbon Fiber Gurney Flap

The Password:JDM Dry Carbon Fiber Gurney Flap / Wickerbill is a short lip that protrudes upward from the upper trailing edge of the 2013+ Civic Si 4DR's factory wing. It’s used to enhance the wing’s downforce characteristics by separating the airflow on the back side of the wing, primarily that which comes over the top of the wing. The result creates a localized high pressure zone on the top side of the wing generating downforce. 

 

When used in conjunction with a functional front splitter / canards, you will be able to enhance the overall aerodynamic characteristics of your 2013+ Civic Si 4DR.
