  1. Perfect

    By Kevin November 22, 2022

    Mine fitted perfectly on my 2019 STI wing. I would recommend having a clamp with padding to hold the ends of the Gurney Flap or it will lift due to the wing slightly curving down.

  2. By Tankie June 23, 2021

    It was little bit too long. Both end of the edge are lifting. If it fit perfectly it would be 10 out of 10.
