Dry Carbon Fiber Gurney Flap

The Password:JDM Gurney Flap is a precision-crafted, dry carbon fiber aerodynamic aid designed specifically to fit the 1999-2000 Honda Civic Si factory wing. By protruding upward from the trailing edge, this wickerbill effectively separates airflow passing over the top of the spoiler. This separation generates a localized high-pressure zone on the upper surface, resulting in increased downforce for improved vehicle stability. Crafted from hand-laid dry carbon fiber, each unit is unique and may feature minor, industry-standard variations in the weave or resin finish that do not impact aerodynamic performance. This part is supplied in a natural dry finish without a UV-protective clear coat. The manufacturer explicitly advises against adding a clear coat and instead recommends the regular application of spray-on wax or ceramic coatings to protect the surface from water spots and sun damage. For optimal aerodynamic results, this gurney flap is designed to be used in conjunction with a functional front splitter and canards on the EM1 Civic Si 2-door. As a hand-crafted component, buyers should expect artisanal variation in the carbon weave. Please note that additional shipping charges apply for customers in Canada, Alaska, and Hawaii, which will be invoiced after the initial order is processed.
