Will these work with the small black splash guards that come stock on the GT500? I am wondering if these work in conjunction with the small black plastic splash guards that seemed to have come stock on my '14 GT500. Or if the splash guards need to be removed.

Shagy2shagy

  • No removal of the splash guards is necessary. I have both on my 2014 Roush. They work well together to help keep the lower quarter panel clean as well as a great look.

Question Resolved

would these fit a 12 gt? if so is there ne drilling required?

lilblue24

  • Yes - these will fit the 2012 Mustang GT - I know - I purchased them and they fit very nicely! I suggest that you do drill the holes and bolt them on as I found it to be a better fit and these fit solid once they are bolted on. I did have to drill holes to install - but easy to do and well worth it!

Do they have the roush rear side splitters for my 2011 mustang ?

Hope1101

  • YES. You have to be a little creative in lining them up and drilling a couple of attachment holes -- but it can be done. I put them on my 2012. Lots of people do.

I plan on ordering the MMD rear valence diffuser for my stang and I also think that this might add a decent accent to it, I wouldn't think that there would be any fitment issues but I would like to ask to make sure, will it all fit together back there no problem?

    It really completes the look for the 2012 boss's

    I bought these to go along with the rough side splitters. They are listed as not fitting the 10-12's and rightly so. They can be made to fit with some trimming of the rear valance though. Definitely worth going through the hassle or trimming to make them fit. If your not afraid of making them fit I highly recommend them.

    Rear Side Splitters

    I have a 2012 GT Mustang and I wasn't sure that these would fit as it states these are for the 2013-2014 Stangs! So I took the chance and Boy was I glad I did! These fit Perfectly on my 2012 Mustang GT! These need to state that the fit 2012-2014 Models as I'm sure others would buy them if they stated this. Only issue that I had was the hardware to instal them - I went to Home Deport and purchased 10 Stainless screws and lock washers ($6.00) and found this MUCH easier when installing than to use the ones provided with the kit. I took my time and when these where installed - they looked TERRIFIC!!! If you own a 2011-2014 - these will fit with no issues! I hope AM reads this and changes the description as I wanted them to look good on my GT but read that these where only for the 2013-2014. Well, they are for the 2011 & 2012 as well. Only gave them a 3 Star as the cost for 2 pieces of plastic was high, but the quality was good! If these where sold as $75.00 - more would purchase. Love the look and Love AM as this was one mod I'm glad I took the chance to install!

    Perfect for 10-12 GT500 with the matching side splitter

    I bought the Roush side splitters for my 12 GT500 last December. I just added these rear pieces after debating. I must say they match the side pieces to really complete the look, and I don't know why I didn't do it sooner. As others have described, they are very slightly off from the 13-14 fit, but hardly noticeable at all. I'm very fussy -- and they pass my test! I lined them up with clamps, scribed marks on the plastic valance underside, drilled a few holes and ditched the supplied hardware for some self tapping trim screws instead. The screws together with the supplied 3M tape are all you need to hold them tight. This mod is easily reversible. I personally think they look BETTER on the 10-12 cars with the black rockers than the 13-14 cars with color-keyed rockers. Roush missed the boat in not marketing these to the 10-12 guys. I highly recommend !!

    Definitely finishes the lower lines of the car.

    I put these on my 2013 GT/CS and they really finished out the lower lines on the car. Definitely makes it flow better when looking from front to back and sets the car apart from others with just a subtle change.

    Roush Side and Rear Splitters

    Installation was a success. I'm always skeptical when it comes to the dreaded drilling, but I took my time and the outcome is, well, magnificent !!! These aide my Shelby by keeping the road debris free from the sides and rear which was their intended purpose as well as the looks....

    Rear splitters

    The fit and finish of this product is unparalleled, and it gives your car a real race car appearance. A side benefit is also that it will help keep debris off of your painted bumper. As far as the install equipment, take the "template" and throw it away, it is easier to use the splitter itself as a guide. If I do have any complaints, it's the price, it's a little steep for what they are, but overall a very good product from Roush.

    Kind of pricey

    I added these to keep the rear quarters from getting blasted, they did require some drilling and while I am happy with them, they are a bit expensive for two pieces of plastic.

    Well built

    I really liked the way these installed. Very solid. Not just some cheap two-sided tape. The alcohol wipes, 3M adhesion promoter, and 3M tape helped hold everything solid after you drilled the holes, installed the nut clips and put in the bolts. These look nice and subtle. Thanks.

    Whole splitter

    I would recommend this to anyone looking for a complete look to their mustang. I own a 2014 Mustang GT/CS with a splitter on the front, I had to purchase not only the Roush side splitters but also these rear splitters to give it that complete splitter look all around my car. The installation wasn't cheap. I could of done this myself but I didn't want to mess it up so I had a ford company installed both the side and rear splitters for 260$ This is a great product to get with the Roush side splitters. I'll have to upload some pictures to show everyone.
