EVS Tuning Carbon Fiber Gurney Flap operates by increasing pressure on the top side of the air foil, decreasing pressure on the suction side, and helping the boundary layer flow stay attached all the way to the trailing edge on the suction side of the airfoil. Perfect solution for those running a front spoiler or splitter on their Type R. Carbon fiber throughout, installed with 3M double-sided tape. Only fits original spoiler for Honda Civic Type R 2017-2021.
Recommend cleaning the wing area with alcohol.
Also wings might need to be sanded down on the coners.
