      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.

      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 recommend pre-fitting all items before they are installed or painted.

        Fits good! few bolts short

        It seems to fit pretty good, although I guess there's more bolt holes in the chin spoiler than bolts provided, but its not like it's going anywhere. Not bad overall. VERY shiny chrome emblem

        Mach 1 kit conversion

        Decided to take on installing a mach1 chin spoiler and grill delete. The grill delete was fairly simple . Although the bots on the bottom were a pain it finally came out . Install was easy The chin spoiler was a bit more difficult but with patience it came along and looks great

        Great stuff

        Was all good, but could come with more hardware for the grille delete, but was a nice edition. It’s a lot to pay for two pieces of plastic tho

        Mach 1 grill delete and chin spoiler

        I love it! Makes the car look aggressive the chins makes the front looks way better and if you have spings in your car it give you that good height look.

        Love the look!

        The Mach 1 chin spoiler and grill delete should have come stock on all 99-04 mustangs. It really gives the front end that mean muscle car look! The only thing that I wish was different was that the chin spoiler has about 1”-2” on each side where it’s not even with the wheel well, but it still looks great either way!

      I noticed that they offer the pony emblem in black as well. Is there a way that someone could request the black emblem, if wanted. I would like to paint it, so I would prefer not to have to deal with the extra prep work involved in painting chrome.

      • We do offer the SpeedForm Mach 1 Grille Delete with a black pony emblem but unfortunately we would be unable to break up this kit to use the black emblem in placed of the chrome one. You can find the SpeedForm Mach 1 Grille Delete Kit w/ Black Pony Emblem here: and the SpeedForm Mach 1 Chin Spoiler here:

      I ordered this kit without the grille frame and my mustang doesnt have the factory frame in it, can I buy the replacement frame separately somewhere? I bought my mustang a couple months ago and I am upgrading the performance and looks and i put in this combo kit without the replacement part and i went to put on my grille delete and I found out my mustang doesnt have any grille frame in it. Can I buy the replacement here or somewhere? I have looked on ebay and all I could find was a one piece frame that is the frame for the headlights as well, I dont need all that. 2 answers
