    Video Review & Installation

    Hey, guys. Justin here with and I'm going to be taking a closer look at one of the most popular spoiler options available for your late S197. I'm talking about this GT500 Style Spoiler, available either unpainted or pre-painted, fitting your 2010 through 2014 Mustang. When weighing your aftermarket spoiler options for your S197, I think you'll find the hands-down favorite with many owners out there, myself included, is the GT500 Style Spoiler for many different reasons.The biggest reason being it really adds to the aggressiveness here at the rear of the car without being over-the-top. As for the build, guys, we're looking at a durable yet very lightweight AVS plastic for the construction. Now as I mentioned at the top of this video, you do have the option of grabbing this spoiler either unpainted, if you have a paint hook-up or if you're going to paint it yourself, or for a few bucks more you can actually spring for the prepainted version, which we have installed on our 2011 GT here.Now the prepainted parts do get sprayed right here in our state-of-the-art paint booth at AM and the best part is, since we use the same paint and clear coat that Ford uses in their factories, you can expect a perfect color match right out of the box. Getting your new spoiler installed on to your ride really isn't that hard of a job but you will spend a little time removing that factory spoiler, which can be a little stubborn. My advice, use a heat gun or a hair dryer or something similar and just take your time. Now once you get that thing out of the way, it's simply a matter of just cleaning and prepping the area using the supplied alcohol prep pads and that 3M adhesion promoter and then getting this thing installed into place.Now the nice thing about this particular spoiler is that you do reuse the bolt holes left by your factory spoiler so no drilling necessary. Now we do call it two hours here on the site but again, expect most of that time to be spent removing that factory spoiler but again, guys, hit up a Mustang expert here at if you have any questions or concerns. So if you're looking to grab one of the hottest spoiler options available for your 2010 through 2014 Mustang, then be sure to check out either an unpainted or a prepainted GT500 Style Spoiler at your Number One source for everything Mustang,
