APR Performance Porsche Cayman GT4 Wing Extension Kit W/Carbon Gurney Flap - AA-545052

All wing pedestals are constructed with billet 6061 aircraft aluminum. They have been designed to change the height of the wing without drilling a new set of mounting holes for the trunk. This simple modification can raise or lower the height of your airfoil for optimum positioning of clean air contact with wing foils. These Gurney Flaps are super lightweight, made in carbon fiber using the pre-pregnated dry carbon process, and conform perfectly to the contours of the Cayman GT4-airfoil. They are easily attached using the included double-sided tape.
