The STI gurney flap is a great way to add some style and enhance your downforce characteristics. 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. Note: Please note that the OEM spoiler is not included and is required for this product. Drilling is required to install this as well.
