Hey, guys. Stephanie with AmericanMuscle.com, here with these lowering springs from Ford Racing for 2015 and up S550 GT and EcoBoost Fastbacks. The Ford Racing X-Springs are gonna be a good option for those of you out there that are looking for a lowering spring for street and occasional track use that's gonna maintain ride quality but still provide performance and still get rid of the majority of the wheel gap that the S550 has. These springs offer a drop of one inch all the way around the car, which is enough to lower the center of gravity to provide some handling improvements, like reducing squat and body roll in corners and eliminating nose dive under hard braking. A one-inch drop is also gonna improve things on the appearance side, so no more big wheel gap, and you'd be surprised at how well the S550 chassis responds to just a one-inch drop in both the function and the looks categories. The one-inch drop will keep a little bit of space between the tire and the fenders, but it's even-looking and I wouldn't consider it a gap anymore. It's a functional low, and by that, I mean it's low enough to look good but not low enough to causes issues either on the tire or under the car. It's gonna leave you with a very streetable car still. You may have already noticed, but the majority of springs are only offering a one-inch drop because the S550 chassis doesn't need a huge drop to obtain better looks or an improvement in handling. The S550 responds well to what some of the older generation Mustangs would consider a very small change in ride height. There are some springs that'll give you a larger drop, but not by much, but they will still get you lower if you're looking for the maximum drop from a spring. And these are gonna be compatible with both the factory and aftermarket wheel and tire setups, which is just another plus of the 1-inch drop. Just for reference, we did install these on our 2015 EcoBoost with 255/40-19s and 305/35-19s on the rear. The drop will look a little different, depending on your wheel and tire setup. The other thing to consider when you're shopping for springs, besides the drop, is ride quality. These are a progressive spring, which means that they have a progressive spring rate, and that means that they're a good option for a street car. They don't have a harsh ride quality, but they will firm up as you start pushing the car, which works to give you the best of both worlds between comfortable and functional. Normally the trade-off with springs is less ride quality for better performance or a better look, since in typical fashion, the factory suspension is set up more for having a comfortable ride quality and being easy to drive than anything else. The stock springs are soft and they allow for wheel hop and a lot of body roll in the corners, so there's a lot of room for improvement. As far as ride quality, though, these aren't far off from stock. They're not a stiff spring. They are more forgiving. You'll probably notice a difference in ride if you drive your car every day. It will be a little stiffer, but it's not uncomfortable. Overall, these springs are intended for street or occasional track use, so they do give a stiffer-than-factory ride quality. But they're made to not be harsh, so still comfortable but also able to perform when you want them to. Ford Racing does also offer a track spring if you want something more along those lines. As far as price, these springs are gonna be right in between $200 and $300 mark, which is right where the majority of other springs are falling as well. Of course, there are some breakout springs that are either less expensive or more expensive than that and even springs that are all across this price range. At the end of the day, it's really about what you want from your springs and what you plan on doing with your car, and that will help direct you to the right spring. So the install here is gonna take about four hours, and I'm gonna call it a solid one out of three wrenches on the scale. Because you will need some knowledge to complete this install, so I'd recommend having a knowledgeable helping hand or taking this to a shop for the install if you haven't done this before. It's always good to get an alignment after the install. This install can be done on jack stands if you don't have access to a lift, but as usual, a lift would be your best bet here. You're gonna need a few tools, including a spring compressor, so make sure you have that before you start the install. You're gonna need to get down to the spring and strut assembly, so everything like the wheels, brakes, ABS line, and will need to be moved out of the way so you can pull the assemblies out of the car. The spring compressor will help you remove the spring from the strut and install the new front springs, which are compressed and installed the same way. The strut assemblies go back the same way they came out, and the install's the same for both sides. The rear is where things are a little bit different, but nothing crazy here. Essentially the IRS subframe will be dropped, along with the rear shock mat, so you can slide the rear springs out. Just like the front, the rear springs install the same way they were uninstalled, no surprises here. The new bump stop is slid onto the shock followed by the factory dust boot. The new spring can then be installed, and the IRS subframe can be bolted back up. That's about all it's gonna take. Like I mentioned earlier, a fresh alignment after the install isn't a bad idea. Wrapping things up here, the Ford Racing X Lowering Springs offer a one-inch drop all the way around, they have a progressive spring rate, and they're designed for street and occasional track use. As always, I suggest you check these out more online for yourself, and for all things Mustang, keep it right here at AmericanMuscle.com.

Improves Handling. Installing a set of progressive rate Ford Racing X-Springs will lower your Mustang's center of gravity, which will reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. Ford Racing X-Springs are great for daily driving, street, and even occasional track use.

Aggressive Stance. The Ford Racing X-Springs not only improve the handling of your S550 Mustang, but they also improve the overall appearance by lowering the ride height approximately 1.0" to eliminate that nasty raised 4x4 truck look for a more aggressive muscle car stance.

Clears Stock and Aftermarket Wheels & Tires. These lowering springs were engineered to be compatible with your factory size wheels and tires, as well as AmericanMuscle's pre-configured wheel and tire combo kits (specific to your generation), to assure proper clearance with no rubbing issues.

Application. This set of four Ford Racing X-Springs are designed specifically for use on the 2015-2017 GT and EcoBoost Fastback Mustang models. Does not fit convertible models.

Will these springs also lower a performance pack gt 1" or is thia for a base GT. I have seen some places say the PP GT is already .5" lower but I can't confirm this to be true.

Matt

  • Thank you for your question about the Ford Performance Street Lowering X-Springs - Fastback (15-17 GT, EcoBoost). The 1 inch drop is going to apply to the Performance Pack GT. The Performance Pack GT does come with springs rated differently than other GTs, but the overall ride height would be the same.

Hello guys. I drive my car daily to work, don't track (drag) the car often. Are these the right springs to use with a '17 Perf. Pack GT or are the Track springs a the right combination?

ErikT

  • Yes, this will be able to be used on that style of car without issue, with it being a progressive spring rate, the quality of ride on the vehicle is mostly unchanged until cornering harder or going at a higher rate of speed, making it excellent for a daily driver.

I have a v6 2015 it this spring fit in my car?and if it fit how much drop do i get?

Fg1920

  • These springs should work with the 2015 V6 as the body of the V6 is a similar weight to that of the EcoBoost and the GT models. As far as the drop goes, you will be able to estimate the same drop which will lower your vehicle one inch when installed.

Hi will go on a convertible if not why? I like to know thank you.

  • Hello! These are not compatible with convertibles, this is due to the increased weight of the convertible. We do offer spring options for Convertibles however these will not work.

    These make for a perfect drop in my opinion. Nothing extreme but definitely noticeable and gets rid of the major wheel gap. I can still clear my driveway and moderate bumps without any problems. I have not noticed a big change in drive quality on my PP mustang. Everything feels about the same to me. I love the look it gives though! Paired with 25mm spacers on all wheels looks great! No rubbing.

    I really like the look of my GT after dropping it 3/4"-1". Fender gap is greatly reduced. Ride comfort seems to be the same as the original springs. Handling appears to be more crisp. Job is doable, just make sure you have decent spring compressors. Don't buy the scissor spring compressor from Harbor Freight. Added 20mm wheel spacers that really finish off the look. I do wish they dropped the front end a little more, although I already scrape when leaving my driveway. Had to buy a low profile jack since mine was too high. Costco has a good deal on a low profile jack that works great.

    Great Look

    I did installed these by myself in my garage with a jack and jack stands. I highly recommend that you have a friend help if you do it without a lift. Also I recommend the you use the one piece spring compressor tool. The two piece compressors kept slipping. Overall these springs dropped my Performance Pack closer to 1.5 inches around. It looks really good. The balance is much improved. I drive mine everyday so I do notice a bit stiffer ride, but it's not bad at all compared to how well the car rotates in the turns. These springs are awesome.

    Ford-X Springs

    Ford X-Springs. 1in. wheel spacers all around. Rear tire sizes 285/35/19 not the 275/40/19. No rubbing, no bottoming out, perfect stance and daily driving combination. Very easy to install, right around 2 hours in my driveway. Next mod will be sway bars to tighten up the rest of the suspension.

    The perfect stance.

    The advertised drop is 1" in the front and rear. You would be amazed with how much stock wheel gap you really had once you get rid of it. The car has a great stance, as though it should have come from the factory like this.

    Great shocks

    I received my Ford performance shocks, had them placed on my Mustang by Apple Ford in Columbia Maryland. As soon as I left the dealership, I could see vast change in looks and performance. Just as advertised my car was lowered all the way around by 1 inch. The car responds better during lunch. With the shocks alone I have reduced the rear wheel chatter. There is also noticeably less body roll when cornering. The best thing about them, is that they are Ford motor company products, so there will be no hassles if I have a problem with them. I would highly recommend them to any of my fellow mustang owners.

    Great look with a warranty

    Guys after much debate, I decided to go with the FR Springs because I have the Performance pack 16 GT and they where made for this car. I love the look of the car as well as the handling has improved greatly. Buy this kit, you'll love the stance, feel and look. No scrubbing or clearance issue from standard springs. Plus if installed by Ford, you'll get their extended warranty on the part and install. To me on a new car, thats a plus. I also had Ford install at the same time a Roush Phase 2 Supercharger (727HP), Steeda IRS and Subframe bushings, SR vertical links and FR sway bars. Much improved over the factory performance pack hardware and the performance technician at Ford stated the car was firmer and drove better than GT350.

    Very Happy with the Ford Racing Springs

    I installed the Ford Racing springs and WOW! Car looks way better. I was concerned a little about using these springs as they are listed for use on GT and Ecoboost (how would the drop be on Ecoboost) but the springs have lowered the car pretty much a full inch all the way around. Handling is only slightly different, I only noticed because I drive it everyday, but my wife couldn't tell the difference, which is a plus in my book.

    Worth the money and handles way better

    I have always been worrying about lowering my brand new car but this time I decided to lower my 2016 Mustang GT. I chose this over Eibach because I rather have it made by Ford. I would say drop is perfect amount because it is not low enough to scrap bottom of your car but still looks low enough. I think front is lower than rear by little bit which is good. Handling and braking is way better. I would lower my next car again because my car feels like racecar now.

    I'm pleased!

    I went with the frpp 1 inch drop performance springs. The car feels a lot more firm no more massive body roll and nose-diving during hard braking. Cornering and breaking performance is noticeably improved because of this. The ride quality feels nice, but not as soft and cushy as stock springs (obviously), yet my 65 year old mother says "it still rides nice." Also, I HIGHLY recommend the "Steeda IRS cradle alignment kit" to get the cradle alighlnment correct when installing rear springs. very inexpensive easy to install. I don't see how anyone gets IRS cradle in straight, without the steeda alignment bushings. << A must <<

    Factory ride and Factory quality!

    I have the performance package and I can not tell the difference in ride quality. (Smoothness of ride) of course they are stiffer but its a sports car! Not bouncy at all and handles great. I can take corners on expressway exits at 60 with no problems. Could be lower for the better look but you would also scrape up you car alot and damage the undercarriage.

    These springs dont make a huge difference and most people wont tell the difference unless you compare it to another S550. Went with the ford racing springs to retain the factory warranty. Ride quality is barely stiffer than performance pack springs, no more nose dive/ body roll. Very satisfied with these springs but now that they are on I wish they were lower.. If you really want the perfect look for your 2015 Mustang, buy these springs, ride quality is nearly identical to performance pack springs.
