Review & Installation Video

Hey everyone I’m Justin with, and I’m taking a look at a product that many Mustang owners believe should have been standard from the factory. Talking about this Mach 1 chin spoiler for your 99-04 V6 and GT Mustang. The spoiler is made from durable, impact resistant materials and it needs to be as it’s a little closer to the road, which makes it more susceptible to road hazards, curbs, speed bumps, whatever. Now I’m not saying it’s impervious to those things, however I will mention it probably withstands the abuse a lot better than some of its competitors. The kit comes with all necessary hardware needed to install. Now the spoiler itself is shipped rolled so you’ll want to let it sit out for about 24 hours, just to let it settle into shape before installing, now if you want to speed this process up a little bit, you could always hit it with a hair dryer, or maybe even a heat gun. The spoiler mounts to the underside of your stock bumper so you will need a drill, and some other basic hand tools, we just used an 11mm wrench, and a Philips head. Now you will make life a lot easier if you go ahead and get the front of the car up in the air a little bit, whether it be jack stands, ramps, a lift, whatever it may be but believe me you’ll thank me later. Install – pretty straightforward, should take you about 30 minutes. Now there’s a couple of different schools of thought pertaining to the install, some of you mentioned you like the look of the lip when its mounted flush with the front of your bumper, however if you’re trying to achieve the look of the true 03-04 Mach 1, then you want to recess the lip back about a ¼” like we did with our V6. Chances are if you’re already watching this video then you’re probably already aware of the fact that the front of these Mustangs looks a little unfinished, that’s where this Mach 1 chin spoiler really shines, it finishes off the front end of your New Edge Mustang perfectly.

Aggressive Mach 1 Styling. The SpeedForm Mustang Mach 1 Style Chin Spoiler is the perfect styling cue to give your 1999 to 2004 GT and V6 Mustang or the 1999 to 2001 SVT Cobra the aggressive front end of the 03-04 Mach 1!

Durable Construction. Unlike other SpeedForm Mach 1 style Chin Spoilers on the market that use thin, fragile materials and inferior plastic mounting hardware, our chin spoilers feature thicker, stronger materials and include solid metal fastener hardware!

Easy Installation. Mounting the SpeedForm Mach 1 chin spoiler is simple with the included nut and bolt hardware, and only takes 30-minutes to change your Mustang from a pony into a stallion. See the video below.

Application. This SpeedForm Mach 1 Chin Spoiler fits the 99-04 GT, 99-04 V6, and the 99-01 SVT Cobra. It also fits the 03-04 Mach 1’s as a direct fit replacement for your damaged factory chin spoiler.

Installation Note. For true aggressive Mach 1 OEM styling, be sure to tuck this spoiler a ¼ inch back from the front of your bumper. This will allow the edges to fit flush with the wheel well opening and really make your stang chomp at the pavement. Chin spoilers are shipped rolled, when unboxed they will cure to their original shape. It is recommended to pre-fit all items before they are installed or painted.

Flush fit and color? I have two questions. The first being, can someone explain what everyone is talking about when they refer to the flush fit of the chin spoiler? And just wondering what everyones opinion is on leaving the c.s. black on my white mustang. Thanks !


  • You can either install it flush with the bottom of your bumper or you can install it back a ways for the actual Mach 1 look. Personally I did it flush with the bumper and it looks ok. As for painting it I would leave it Black as it will be more noticeable especially on a white car. I have had 2 White Mustangs and I always liked the Black on White look.

Can this chin spoiler be painted to match my car?


  • Yes, they can be painted. Surprisingly, they look pretty good with the spoiler matching your exterior paint code. Look around on the internet for some pictures. I'm just wondering if you were to nick it on a curb, would it crack the paint because it is somewhat flexible.

I do not want AM staff answering this because I already know what you'll say but has anyone tried to put this on a 03/04 cobra? I'm not looking to spend $500 for something that's worth $50


  • Hey Zach, Since the front bumper on the terminators is vastly different, to get this chin spoiler to work you would need to custom mount it. So where the curve for a cobra chin spoiler is will be different than the one for the mach 1 and the application may come up short as well as not fitting the contour of the bumper completely. So yes the direct answer is no it will not fit, but bending/remolding of the chin spoiler may allow fitment but its not guaranteed.

    Aggressive Look

    I ordered this Chin spoiler and was a little skeptical due to it's the cheapest on the site. But after installing it and seeing how it looks and fits, I couldn't be happier. Easy to install, no need for instructions (does not include). Jack up your car find the center of the lip, match it to your car mark it with a sharpie and start drilling. I just finger tightened the passenger side then the driver side, then held it up and drilled the center, and went from there. Super easy.

    looks great, takes more than 1/2 hour for install

    Received my chin spoiler in less that 24 hours...looks great right out of the box, but don't be fooled by the install time (of claimed 30 minutes)....If you have to drill all the holes like I did, plan on at least an hour to hour and a half to get the job done right, but well worth the time and effort.....

    Effective Black Out Styling

    This product is a great Mach 1 appearance update. Simply drill the holes and screw it on.. I put my chin spoiler back from the edge a couple centimeters to get the 1970's look, but you can also fit it along the outer lip for a good look. Only thing to complain about was the product can be a bit picky when it comes to bending it to the right shape. Price is high, but it's the safe option if you want a good mach 1 chin spoiler.

    chin for cobra.

    just what my front bumper needed for that finished agressive look without over doing it! love the flat surface rather than the rough finish that some others have this one you can shine up with you're dash protectant & it looks like you painted it. Install was smooth. would recomend, a nice inexpensive way to up the cool factor on you're stang.

    '01 Cobra Chin Spoiler

    Great addition to car--and good support from AM for the install video and guide. However, the '99-'01 Cobra's front bumper is not as 'round' as the V6's and GT's, so the spoiler (when flush with wheel well) looks silly sitting like an inch back from the front of the bumper. I would recommend making it flush up front, even though the video says not to. Looks WAY better!

    quick, easy, painless, and looks great.

    The chin spoiler added a much needed aggressive look. It is cheap and simple to install. Only took about an hour to install. I would recommend having a friend help, much easier that way. If you think it is too much work, it's not. All you need is a 11mm wrench, screw driver, drill, and a 1/4inch drill bit. Drill the center hole first and put a bolt/washer/nut in then do both ends closet to the wheels next. Then work your way to the center from either side. I would also read and watch the installation guide. I was missing 3 bolts, 4 washers, and 3 locking nuts. I went to Home Depot and found the exact same hardware for a total of $2.00. If I wasn't missing some final pieces it would get 5 stars.

    Easy install. Great looks for such a simple addition. i agree with others, this part should have been stock. Don't worry about the part being rolled up in packaging. The spoiler unraveled fine, although, this Texas heat sure helped speed up the process.

    Chin Spoiler

    A decent product. I set it out at room temp to "uncurl" after shipping. Installation should have been a breeze, but I didn't like the metal hardware. Chin Spoilers tend to come out on the losing side of curbs and stops, and if it gets ripped off I'd rather it not take or break my front fascia with it. So instead of using the included hardware I went to Ford and picked up 14 plastic pushset pins.. and they work great. It's not a first class product, it's more like a piece of rubber molding than a chin spoiler, but once installed it looks okay and I suspect will take a fair amount of abuse. I still think the metal hardware (nuts&bolts) are a bad idea. They're not used on pieces like this, pushset pins are used. They're faster, less risky, and require a lot less wrench turning.
