    Review & Installation Video

    Hey, what's going on, guys? Justin with AmericanMuscle.com here. As you can see, I've my '14 G.T. back in the shop. I'm doing a little bit more work on it today. You guys seem to be really digging these videos, so I'm going to keep bringing them to you. If you caught the first couple of videos, you can kind of see the general direction of the car. Appearance-wise, I have that GT500 theme going on, thanks to the matte white stripes on the white car - which I think looks really cool - the GT500 spoilers, and some other little parts. Performance-wise, you saw the Cobra Jet Intake Manifold I did in the second video, along with the big monoblade throttle body, the off-road H-pipe, and the MagnaFlow exhaust. So car's running great, looking good so far, but I definitely have some more stuff planned today. I'm starting off with the chin spoiler here, the ROUSH front chin spoiler, which I just finished up installing. Really a big fan of this chin spoiler. Not a whole lot of options available out there for these generation Mustangs in terms of lip spoilers or chin spoilers. The R.T.R. is nice. It's a little too radical for what I'm going for. Boss is really nice, obviously, but price is a little high for me. So the ROUSH is just right. I like it. Simple lip, yet I think it really adds a lot to the car. So I do have some other appearance stuff going on here today, guys. In addition to some stuff inside the car finally. So let's go over to the side, and I'll show you some more appearance stuff. All right, guys. You've been hearing me talk about it for the last few videos and guess what? The nice weather is finally here, so finally been able to throw on my new wheels, and I could not be happier. I went with the '13 and '14 GT500-style wheels wrapped in the very good Mickey Thompson rubber here, and again, the 28's in charcoal. I think they look awesome on the white car, and they really just nail that GT500 look that I've been after ever since I bought this car. So my vision is finally kind of coming together, thanks to these wheels. In addition to that, guys, I also did the ROUSH side and rear splitters to go along with that front chin spoiler from ROUSH. I think the total package just really adds a lot to the car in terms of appearance, and just gives it a much more aggressive look. Now, I am going to get inside the car, of course, but I do have one more suspension part I want to tackle before I do so, so let's check that out. All right, guys. Ryan and I just finished up installing the S.R. Performance lower control arms here on my '14. Now, for a lot of Mustang owners, these are actually one of the top mods you guys do when you first get the car because as you probably know the wheel hop on these things is absolutely horrendous. I've just been dragging my feet a little bit on this mod, but now the car is making real good power, I definitely need these to help me get that power to the ground. Very simple install guide. Basically, a two-bolt install. Of course, you want to make sure you get the brake lines out of the way with a big zip tie, something like that. But again, a very recommended mod with these cars, and again, should help you lay down some nice lines instead of wheel-hopping all over the place. With these buttoned up, I'm going to get inside the car and show you guys a couple mods in there. All right, guys. So here we are in the interior of my '14 G.T. where I am doing a little bit of work today. Now, full disclosure, when I bought this car, it had to have a few options. It had to have the Track Pack, Recaros, and the car had to be white. Now, the only car I could find with those options was a base car. So I am missing out on the cool stereo, some of the nice interior touches, and those Track Apps that we all know and love. So I am trying to fix that one at a time, and I'll show you what I'm talking about. First up, I did the Raxiom Navigation. Now, this is an absolute must for anybody without the factory nav. It integrates so well into the interior of these cars, works flawlessly, and the G.P.S. is right on the money. So hands-down probably one of the best mods I've done to this car so far. As far as that boring base dash, well luckily, here the guys at AmericanMuscle Graphics do offer a few dash overlay kits, so I picked up their carbon fiber version, and I absolutely love this thing, man. Slapped it on one day in the driveway at home just in an hour or two, and it kind of gives you that California Special appearance to your dash if you have a base car like me. It just spices it up a little bit, so I really do enjoy that. Finally, I am missing those Track Apps, so I had to take care of that, and what I did was, I looked at the P.L.X. DM-100 Multi Gauge. Now, this thing has a touchscreen gauge, and it shows you all that great OBD2 info, so air-fuel ratio, intake air temp, water temp, things like that. And it can also be used as a performance gauge, so it can tell you your eighth, quarter mile times, things like that. Definitely a nice thing to grab if you don't have those Track Apps because it kind of takes the place of that, and I had a nice, stealthy install here with the gauge pod. So overall, the interior is coming together pretty nicely. A couple of other bells and whistles I threw in was the Modern Billet 6-speed white shift knob, which I just love that retro look, and I also threw in some Raxiom L.E.D. map lights as well. So overall, again, really happy with the interior. I think the car is really starting to come together. Maybe have a few other things down the road here as far as the interior is concerned, but for now, again, really happy. All right, guys. That's going to do it for this installment on my 2014. Thanks for checking out the progress. I honestly could not be happier with how the car's sitting right now. I think it's looking great, definitely making some good power. Now, it's the time to get on the streets and have a little bit of fun. So drop a comment and let me know what you think of this bad boy, and in the meantime, I'll see you next time. Peace.

    Will these work on a 2012 roush diffuser?

    DanielW

    • These will not work with the 2012 Roush diffuser as the rear fascia on the 201-2012 models is different than what is found on the 2013-2014 models.

    Is there any reason that these would not work on a 2012 GT?

    Anonymous

    • The 2012 GT rear bumper are shaped differently which is why these rear side splitters will not work on a 2010-2012 GT model Mustang.

    I have an 2014 Mustang GT with Gt500 quad tip exhaust, will the Roush rear side splitters work with that?

    BobbyHill

    • Yes, these side splitters will work with quad tip exhaust. If you scroll down the page, you will find some customer submitted photos. There are a few customer car's that feature quad tips with the splitters.

    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?

    Austen

    • The Roush Rear Side Splitters (13-14 All) will fit very nicely with the MMD by FOOSE Rear Valance Diffuser (13-14 GT, V6). You should have no problems with these two items.

      Easy style upgrade

      Product shipped quick and came with clear instructions and all the necessary 3M prep material to properly install. Having some painters tape to use for the hole drilling template helps. Only a few holes to drill on the unseen plastic portion of the body panel, so no need to be worried. Matches perfect with the Roush front lip and side splitters and rear spoiler. Only 4 stars due to the price for some cool looking plastic accents.

      Really makes a difference in the rear

      I was skeptical at first especially for the price there asking for 2 pieces of plastic but the install took me 30 min and was extremely easy They look really aggressive and match my oem mudflaps perfectly only reason I gave 4 stars instead of 5 was the price tag kinda steep for what your really getting but other than that was a great purchase and I love them on my car

      Works for 05 through 09 also.

      I already have the CDC front splitter and side splitters for my 05 GT so I was looking for something similar for the rear fender. I saw another review saying that it fit an 08 so I figured give it a try. The finish texture doesn't quite match the CDC brand but its not noticeable when on the car. I chose to install them without cutting them but they can be easily shortened with a Dremel. Since it's for a different generation rear bumper, the template is useless. I clamped it in position I wanted and drilled 1/8" holes based on the existing holes in the splitter. Then I removed the splitter and drilled the 1/4" holes. I applied all of the 3M tape except for the last piece near the rear of the car. The kit comes with metal clips and bolts but the clips wouldn't fit where I drilled the holes so I chose to break the clips and use only the back half with the bolts. You could also use plastic trim fasteners which is how my other splitters are attached. This really finishes the look of the splitters on my car. I uploaded pics so you can see how it looks on an 05-09 before you buy it.
