  • Aggressive MACH 1 Styling
  • Features Thicker, Stronger Construction
  • Includes Metal Fastening Hardware
  • Easy, 30-Minute Installation
  • Fits 99-04 GT, V6, Mach 1 and 99-01 Cobra
Aggressive Mach 1 Styling. The 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 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 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 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.

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.

Height What is the height of the spoiler once mounted from facia to bottom of spoiler


  • I assume you want the height of the bottom of the spoiler to the ground, after installation. My car has stock springs and is not lowered and the distance is eight inches. Bare in mind that the factory air dam behind the spoiler protects the sub frame, so if you park to close to the front axle you will hear it scraping any obstacle in its way. In any event , if at any time you hear a scraping stop. unless you drive a Camaro.

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.

When installing on a Mach 1 do the holes line up correctly? Is this an exact replacement of the one that came on the stock Mach 1?


  • Yes, the Mach 1 Chin Spoiler (99-04 GT, V6; 99-01 Cobra) fits the 03-04 Mach 1’s as a direct fit replacement for your damaged factory chin spoiler.

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.

    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.

    '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!

    Good Looks, Quick and Easy

    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.

    Tough to do but well worth it!

    My advice is to take it one step at a time. Start from the corners and work your way into the middle. That way you can keep the corners flush with the wheel wells.

    Nice addition to my \'96

    Looks great on my \'96 GT convertible. Shipping was quick and the price was good. I used a combination of 1/4\" machine scews and bolts and larger, more robust plastic push-type clips, (alternating, everyother hole). Still all fit the 1/4\" holes I drilled. Try the nuts with the cast-in flat washer and locking design. It is pretty easy to reach inside the bumper cover and hold them by hand. Once they start to tighten they grip, you don\'t need a wrench to hold them. The plastic clips supplied were too brittle and either broke or didn\'t hold tight enough to satisfy me.

    Watch for creasing during packaging

    Nice little dress up piece if you are willing to spend almost $100 bucks for plastic. It looks ok but it would have looked so much better if the guys from the packaging department wouldn't have folded the thing three time to fit it into a smaller box, now I notice a couple of creases on two spots.

    2000 GT Chin Spoiler Installation

    If you follow the instructions given by American Muscle, you will never get the spoiler installed. The spoiler comes from the factory 3/4 inch short at each end (from the edge of the front fender line). Start at the centre and work your way back towards the fender edge. I used duct tape to hold the spoiler in place to drill the holes. The bolts I received were 1.5 inch long. They are too long for this application. All you need are 3/4 inch or maybe 1 inch long bolts. I had to buy a complete set of 17 new bolts to install my spoiler. Aircraft nuts are a must. After installation, my spoiler was short 3/4 inch from each fender edge. No one will notice unless you show them the flaw in manufacturing. Once again, do not follow the installation instructions given by American Muscle.
