    Justin: Hey everybody, Justin with back here with my buddy Mike Smith. Mike, good to see you again, man. Mike: You too, you too. Justin: Absolutely. You guys might remember Mike of course. He brought his brand new 2015 in with us. Did his first run of mods which included that AirAid cold air intake, Flowmaster exhaust, and of course the Bama V2 tune. How are you liking these things so far? Mike: Absolutely loving it. Everything that they did to smooth out that low RPM shifting and everything going into it, the power, the sound, everything that it brought for the Mustang itself has been amazing. Justin: Can't beat it. With over 400 wheel horsepower, too, you've got to be happy. Mike: Very! Justin: All right. Well, just like many other Mustang owners including myself, Mike has been bitten hard by the mod bug. That's why he's back with us today. It's only been a couple of weeks, but you're already back with some new plans. What do they entail? Mike: Well, I was reaching out, trying to look for some things, just to kind of to get a little bit more of a performance stance to it, get it down a little bit, make it a little bit tougher. I'm looking for new wheels. Justin: I think we have something in mind for you, Mike. Mike: All right. Justin: Of course, we worked together on a few parts, and we'll show you guys what we're working on. But for now, Mike, get out of here. We've got to get to work, brother. Mike: All right. Justin: All right, guys, the first part on Mike's suspension and handling build, as you can see we're working on a set of sway bars. Now, he decided to go with the Whiteline front and rear sway bar kit for the 2015 GT which should be a nice improvement even over the beefy performance pack sway bars. Whiteline's looking at a 35 millimeter front bar and a 24 millimeter rear bar as opposed to a 32 and 22 factory bar, which should give the car a lot more grip in turns and make it feel a little flatter as well in turns to basically make it handle a lot better on the street for Mike. Full disclosure, guys, it's a little tricky getting the front bar off, mainly because there's a few bolts you have to get from the engine bay. But, the rear should be a lot easier. And of course, we are going to tackle that rear bar in a minute. I did want to mention real quick, though, Whiteline does include these nice beefy adjustable end links which is a very nice little touch. And, of course, the bars themselves are three way adjustable, so it allows you to dial in your optimal settings, optimal preload, things like that. So, we are going to talk a little bit more about some of the suspension mods that Mike has chosen for his ride here today, but first we're going to finish up getting this front bar installed. All right, guys, what's a suspension build without an aftermarket set of springs, right? That leads us to our next part here in Mike's build, these Vogtland lowering springs which are going to lower the car an inch on all four corners. Now, Vogtland is actually a well known brand in other automotive fields. They've been around for over a hundred years, but they're relatively new to the Mustang game, so I'm really excited to see how they're going to work out on Mike's ride, as is he. Again, the one inch drop should be just right for this car getting rid of some of that ugly wheel gap of course, but the car shouldn't be slammed to the ground. Even more importantly here, we are going to reuse his factory dampers because as of now no aftermarket company has released a set of aftermarket dampers for these cars. So, basically, the factory stuff should be able to handle it just fine, the mild drop and relatively low mileage stuff. So, we're going to get these fronts installed here and move on to the back. And we have a few more things to talk about there. All right, guys, with that last bolt we're pretty much wrapped in the rear. We've got the Whiteline rear bar installed along with the rear springs and we're pretty much good to go underneath the car. Now, obviously, the 2015's do have the independent rear suspension which makes spring install a little different back here. Before with the solid rear axle, you'd just basically drop the thing down and pop both springs at once and you're good to go. With this, it's a little bit more labor intensive. You have to lower the subframe on each side, pull the springs out, put them back in. Not the end of the world, it just takes a little bit longer. So, with that, we're all done back here. We're going to get the car down on the ground and show you guys the last part of Mike's build. Well, guys, as you can see, the third and final part for Mike's build today here, brand new set of MMD Zeven wheels, 19 inch diameter in bright silver. He didn't want to do the traditional black on black or even charcoal on black. Instead, he wanted to do the bright silver. He thought it would pop on his car, and I would totally agree with him. We want to get him in here, of course, and see what he thinks of this thing. I think it looks killer of course. But, we also want to go for a ride and see what he thinks of these new handling parts and to see if they've improved on his handling performance. Well, Mike, moment of truth, man. Springs, sway bars, and of course those MMD Zeven wheels are in place. What do you think? Mike: Wow! Wow! I tell you, instantly, you just look at it, the wheels are popping at it. The stance of the car now with the springs on it just lowered a little bit, filled in all that gap. Justin: Absolutely! Mike: It looks amazing! Justin: Well, there you go. Very nice! I'm glad you're stoked with it. Of course, there's more than just looking at this thing, though. We've got the springs. We've got the sway bars. We want to see if this thing's handling better, so what do you say we hop in and go for a spin? Mike: I'm ready! Justin: All right, Mike. We're out in the car. We've got the springs installed. We've got the sway bars. Of course, those wheels and tires. I have to ask. First impressions of your ride? Mike: It's been awesome! Just the grip, just the handling of everything from the corners to the bumps and everything else we've been going through. It just grips at a whole other level right now. Justin: Absolutely. We're in the Northeast. The roads this time of year are brutal to say the least. Mike: You're going to get a good test right now out of these springs and the sway bar and how it's handling in the corners in this area. Justin: Oh, man! Yeah. Mike: You feel that grip! Justin: Thing just did with no spin at all. Mike: Finally. That's all I've ever wanted from this damn thing and I couldn't get it. Justin: Well there, it's amazing the difference an All-Season makes. Mike: Absolutely. Justin: I tell you what, Mike. We have a hard right hander coming up here. Let's see how these sway bars are working for you. Mike: Man, all right. Justin: We've got another left hander coming up here. Ripping off a downshift. Let's see how she feels. It's a hard one, too. Mike: Oh, man, we're going in. Justin: Yes, sir. Oh, man, overall, a success, you think? Mike: Yeah, absolutely! What a performance handle, and just everything that it has done to wrap it all together with the sway bars from the cornering to the springs. Your number one, driver is the performance piece of it, but also you've got to look at, you want it to look good. Justin: And you got the looks. Mike: And this thing right here, just sits mean right now. Justin: You do. You've got that aggressive stance. Mike: Just right. Justin: You've got the rubber. You've got the wheels. Overall, success. Mike: Absolutely. Justin: There it is, guys. Mike: I'll be back. Justin: Mike, he can't stop man. He's been bitten hard by that mod bug. So, he might be back in a few weeks maybe for that blower we're talking about. Mike: Yeah, you never know. Justin: Well, there you go, guys. You have to follow this build. Mike's having a blast, as are we. Be sure to stay tuned right here at

        2 Top Rated Questions

        Are these compatible with Eibach sway bars? Same question on the white line front end links?

        • Hey Andy, The end links should work with the Eibach sway bars because they bolt to factory mounts as does the sway bar, they are just adjusting the position of the sway bar for optimal comfort.

        Helpful (0)

        Do these end links need to be paired with the whiteline sway bars, or can they be paired with the performance pack ones?

        • These end links can be paired with the Performance Pack sway bar.

            Exactly what was needed....

            Purchased these because I installed Air Lift 3P and the stock sway bars/endlinks will not be adjustable to make the suspension tighter. Install was simple and was able to make my adjustments after a week of testing the suspension. If you have Air Lift then the endlink will come very close to your upper bracket but there should not be any clearance issues. I also had to release the air out of the rear bags in order to install because you have to have enough space to clear the bolt to install. Quality seems good except when you make adjustments it will scratch the paint unless you put something around it.

            These make a huge difference with sway bar combo

            So I did lots of suspension upgrades and two of the most significant upgrades I noticed was the K member brace and both front and rear sway bar links with the eibach front and rear sway bars. The sawy bars alone were good but the difference was small until I added the links and man the difference was huge. Love them and a must buy for suspension upgrades.

            Rear Sway Bar End Links

            Whats to say, it fits, that is what it is suppose to do. They are better than stock items. Will replace the front soon. The front sway bar was the big item. It made my Mustang handle the way it should have from the factory,

            Very Nice

            These sway bar links are well constructed and gave me the reassurance I wanted under track conditions. What I really like was there is less deflection vs the stock pieces which allows me to be more aggressive in turns. I just feel better knowing I have these links installed.

            Must Upgrade...

            ...whenever upgrading sway bars. Stock sway bar links are flimsy. Whiteline sway bar end links are made solid and perform exactly as advertised.

            Great looking product, with very good fitment. Broke my stock ones, which felt brittle in comparison. For the price these are definitely a good buy.
