    My son has an 08 Mustang V6 that has the factory wing spoiler. After reading a few of the answers on here. So, if this car came with a stock spoiler this Speedform GT500 spoiler will fit the pre existing four hole that are already there? without drilling new ones?


    • You will be needing to drill 4 new holes as the holes will not line up with the factory spoiler. A template will be included to assists with drilling.

    Why does the unpainted verson say it will bolt on with the original holes and this one requires drilling 4 new holes?


    Will the screws fit the 4 holes that the wing has been using? Sorry, just wanted to be specific about the holes.

      Nice Product and Appearance

      Own a 2007 GT/CS. Removing the wing and the tape residue takes the longest so be patient. I found a thin plastic putty knife works great at removing both the wing and the tape residue along with some Goop. To install properly I recommend buying some long 1 3/4" 8mm bolts to serve as an install guide. Once you are ready to install the spoiler, peel the 3M tape from the spoiler and then holding the spoiler about an inch off the trunk surface you and a helper thread these longer bolts from underside of the trunk using the proper holes into the existing threads on the spoiler which you are still holding about a 1" above the trunk surface. As you lower the spoiler onto the trunk these longer guide bolts serve as great way to avoid mistakes, and to ensuring that the spoiler lines up properly and the threaded holes are available for final install. Gently lower the spoiler using the bolts as guide and once the spoiler is firmly seated with the tape, unthread the long bolts and replace with the shorter proper length bolts that came with the spoiler. Easy!

      great addition to my exterior mods

      preping for the two sided tape was my major concern.purchased automotive adhesion promoter on e-bay, then installed, very easy to do if you are carefull. you only get one chance if you use the promoter, it grabs the tape firmly gives the rear a good finish without looking to large like some other spoilers being sold

      I like it

      Pros: Paint to match was spot on; American Muscle does a good job with painting Spoiler fits well and looks great Cons: Packaging was not that great. While the spoiler wasn’t damaged, the box had a couple of puncture holes…the shipper’s problem? I guess, however, the OEM needs to account for potential shipping problems, especially when the customer is paying for painted parts! Instructions were not very good, seems to be a recurring theme for this manufacturer. Example, if you are installing alone, cut the heads off a couple of 2” long bolts and finger tighten into the spoiler, so it makes it easier to align with the holes in the trunk lid. Then remove temporary alignment bolts and install the provided hardware. Other – Removing Adhesive I see that other posters have had issues with adhesive when removing adhesive applied emblems/spoilers, some suggesting using scrappers, and while a plastic scrapper may work, the likelihood of damaging paint is high. Using a length of fishing line, drawn under the part to be removed is a much better method to remove. Simply hold the line in each hand and draw the line back and forth under the item to be removed. After the emblem/part is removed, “adhesive release” will help to remove remaining adhesive. Also, using a 3M “Stripe Off Wheel”, (eraser wheel) is a better method to remove remaining adhesive, vinyl stripes or decals. Around $25 to $30 dollars at most automotive paint supply stores, or the Internet. This is far less costly than having to repaint!

      Great replacement of factory rear spoiler

      The GT 500 spoiler is an excellent replacement of the stock spoiler that came installed on my 2007 V6. Never did like the original spoiler. This one has a much more aggressive look without appearing ridiculous as some of the other aftermarket models, and the paint was a perfect match. It reminds me of the spoiler on my 1974 Trans Am I owned many years ago. As the other reviewers stated, the hardest part is removing the factory two-sided tape from the rear deck. A plastic scraper and acetone USED SPARINGLY will eventually work, but you have to be very careful not to scratch the clearcoat finish, although most of it will be covered over by the new spoiler anyway. The holes line up perfectly with the holes in the rear deck, but you have to be very careful to get it right the first time. Once the pre-installed two-sided tape on the new spoiler makes contact with the rear deck of your Mustang, its pretty much stuck for good. In order to get all the holes lined up, I put 1/4" x 1" wooden dowels in the screw holes in the new spoiler and lowered it slowly until the dowels went through the rear deck. Once the spoiler was fully seated I just used pliers to pull the dowels out and the screws went in perfectly. Having someone help you will make this much easier.

      Spoil Me

      The project took about 2 hours. Longer than I expected due to the massive amount of adhesive that had to be removed. I used Goof Off as the remover. I used Qtips stuck in the spoiler screw holes to help alignment with the holes in the trunk lid. Fit and color were perfect. It looks great.

      GT 500 Rear Spoiler

      By far the hardest part of the installation was prying the stock spoiler loose and removing the adhesive. A little GooGone and a lot of rubbing with your finger tips. Did it carefully, so that part of the job took a couple of hours. Once everything was clean, I peeled back a couple of corners of the new spoiler's adhesive tape and carefully placed it on the deck lid, lined up the included bolts (just to barely catch the threads of the spoiler). When I knew I had it in place, I removed the adhesive tape slowly, working it from end to end. May have gone a little easier with two people, but I just couldn't wait ! Total time was about 3 hours. Looks awesome !

      Love the spoiler

      Pre-painted spoiler very nice. Installation instruction ok if you have a factory spoiler. Mine came without one. there are 4 strips of heavy paper with a hole in the center. Apparently you are supposed to remove the little sticky square that is around the hole and stick it to the spoiler. Then while holding spoiler in place tape the paper strips to the trunk and then slowly remove spoiler so you can drill holes. I reccomend that you drill the two outter holes to aid in securing spoiler to trunk. This area is double wall thick and hollow in the middle. I drilled thru the inner panel with a 1/2" drill bit so I could recess screw and then covered hole with a plastic plug I found at Pep Boys. Over all be patient and careful and it will look great.

      Looks Great

      This looks great on my 07, but I was a little disappointed it only reused two of the four factory holes. And this spoiler does NOT cover the same surface area as the factory spoiler. Mine being an 07 there is a very noticeable line on the top and bottom from the old spoiler. So you must be prepared to spend a few extra bucks to buff out the difference in the paint.

      Small issues

      For an '06 GT. Pros: Nice, different look. Paint match spot on. Cons: 1. Without making a template and drilling the outer two holes (stock for the GT500 obviously), you're depending on the tape to hold this down on the outboard ends. Mine was not an absolute flush-fit so if the tape doesn't hold, the ends will work their way up. 2. The tape is visible when looking at the spoiler from the front. You can see the white of the tape. My kids suggestion is to use a red Sharpie to color it in. All-in-all, I'm very happy with it. Used 3M adhesive remover to get the stock glue off; worked very well. Was kind of scary trying to get it on with the tape exposed, trunk up, etc. Put a screw through the hole (you only use 2 on this; not 4 like on the stock spoiler) and managed to get it lined up and tape set correctly.

      The spoiler match my cars paint perfectly. Installation was simple and easy the only thing that takes time is taking off all the old spoilers glue tape. Had to get some car adhesive remover at autozone which help a lot. Other than that the spoiler fits perfect and change the look of the car making it look a lot better than before.

      Mustang GT500 Spoiler

      Looks great ! I liked the factory spoiler too, but this just flows nice with the overall body lines of the car. Like others have said, removing the factory spoiler was the toughest part of the job. The adhesive is definitely meant to stay put. Just take your time with this part and the rest is easy. I cut the heads off a couple of bolts to make alignment pins. Then set the new spoiler in place and used some pieces of tape to make reference marks around the front edge. Made it easy to see where the new spoilers tape would make contact and show me where to clean with the alcohol swabs. After cleaning, I could peel all the tape and simply line up the temporary pins. Once stuck down, remove the pins and replace with the supplied bolts.
