This product. I can't express to you how satisfied I am with it! At the time of installing this product I was running a front bumper splitter and cannard set-up and all I needed was some aerodynamic increase on the rear of my vehicle. I got all of that and more when I installed this thing onto my car. The traction increase of my car actually took a little bit of getting used to, but boy does this thing stick to the road. I went from having to handle curves and corners slow to being able to DRIFT A FRONT WHEEL DRIVE CAR AROUND CORNERS! Keep in mind that I'm not running with performance tires either, just the cheapest tires I could find for my car. (I do not endorse street racing, all testing was performed on local tracks) Just to note, my vehicle does not have traction control, since it's an 08 model, but the difference in traction was immediately noticable. The build quality is very strong and secure, I haven't worried about the wing becoming loose or migrating/shaking since I installed it. this product is a bolt-on design which means if you plan on installing it onto your vehicle on your own like I did, double and triple check you measurements and placement! Once you drill those holes in the trunk, they're there for good! It also doesn't come with installation instructions either, so if you can't figure out how to put it together, take it to a shop! it is very simple and easy to paint as well, so if you don't like the matte black finish you can paint it as well. I decided to paint it since I'm going with a Navy Blue Angels theme on my car. The finish on the wing was very nice and smooth, no bubbles or bumps! super happy with the performance and appearance! 5/5
