I have been collecting a lot of cardboard boxes (mostly because it was easier putting them in the corner of my room than taking to the curb). Tonight is the night I put them to good use. I have a friend coming over (driver of that red miata) and we are going to mock up some DIY aero. I am hoping to get some canard templates made up, and my new rear diffuser. I am looking for something more aggressive, and something that fills the rear bumper more.
