Hey everyone I tried searching for something like this but nothing could answer my question. I am in the search for a functional yet appealing spoiler for our cars. I plan on doing some track time and autocross in the near future. I have looked at the INGS Z-power wing but they could not tell me if it did anything. I am assuming the Nismo wing does something based on it’s a freak ‘in NISMO. But any help would be much appreciated. Thanks.
