        Does this stick out more than the Roush chin spoiler? I'm looking for the most aggressive look. Thank!

        I am having a similar issue as someone else who posted a question here. The stock splashguard isnt long enough, so there is a small gap between it and the new chin spoiler. Is this normal, and will it impact the car in any negative way? Thanks. 1 answer
        I bought this and it fits in place of my 19’ base lip but I wasn’t able to reinstall the plastic splash guard underneath the car. You said it fits every car but it didn’t with mine. The splash guard was too small after the install of this lip because the lip is wider around the corners than the stock lip. Unfortunately I’m having to return it tomorrow, any insight because I really wanted to keep this on my car. 1 answer
        My Current Sto n Sho is for my PP1 19 GT,i imagine this wouldn't work right? I'd need the PP2 Sto N Sho if i were to install this splitter? 1 answer
        Will you be posting a review and installation video for this item? I have seen that with other chin spoilers on your site there can be complications with the installation based on if the car is a base model vs. a PP model. I want to make sure there will be no issues having this fit correctly (without modifications) on a non PP mustang GT. Thanks. 1 answer

            Great aggressive look !!

            Been eyeing this spoiler for a while and finally pulled the trigger BFsale. Arrived on time and undamaged. Install was a breeze, just watch the installation video and definitely follow tool guide. Easily put on by myself in driveway in under an hour. Found in the end I was shorted 1 bolt and substituted some strange looking screw. That's the reason for the 4 star overall. Great product for those looking to make their Stang look like it's ready to eat up the road.

            I am very happy with this lip spoiler and it was easy to install. I am not currently running a belly pan but it has not made a difference for daily driving.

            This spoiler is aggressive looking. Love it! Here is the conflict - the performance splash guard that needed is nowhere to be found. I have called Ford dealers and they are stumped. IF you google the model number there are several sites that come up. I bought one that listed the correct model number but it was the one that was already on the car. I have rigged the stock splash guard for now. Still looking for the performance one.

            Excellent chin spoiler!

            The MMD chin spoiler is a quality piece. The fit is superb, I had no issues installing it. I installed it on my 2018 GT vert, non-performance pack. I did also buy and installed the pp1 lower air dam/belly pan. It was well worth the effort. This chin spoiler looks like it came from factory and gives the car the perfect amount of aggressive looks. I would definitely buy it again.

            Much better than expected.

            Only took an hour and a half or so, very straightforward install if you use the video that AmericanMuscle made on the product. Looks significantly better in person than I was expecting, body lines flow well so much so that it almost looks like it could have come from factory, but when compared to the factory spoiler, it’s larger, slightly lower, and much more aggressive.

            Great piece

            The piece is of the same quality as the original chin spoiler but looks 10x meaner. Just don’t forget to buy the PP1 belly pan separately if you don’t already have it. Can be installed pretty fast if you have the right tools.

            Amazing change

            The MMD chin Spoiler fits perfectly and looks factory. I did have to order the factory belly pan or air shield for under the car to complete the install but was over all an easy installation. Love the way it makes the car look

            Nice visual upgrade

            Great fit. Was able to install without lifting the car, but would certainly be quicker with a lift. This will fit without the performance pack belly pan, but the pan should be upgraded. The splitter doesn’t go far enough under the car to fasten the pan too on the outer edges.

            Big Front look upgrade

            One of the first major mods done to my 2019 GT PP1 during the first week that I got it. It has greatly improved the appearance of the front and side profile of the car. Super simple to install no more than 1hour. A must have mod for any 2018 to 2019 Mustang.

            Great Product with one exception. The ends that face the wheel (tire) should have been closed. These are open and IMO look cheap and unprofessional... like a unfinished product
