Review & Install Video

Improves Handling. Installing a set of progressive rate Ford Racing P-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 P-Springs are great for daily driving, street, and even occasional track use.

Aggressive Stance. The Ford Racing P-Springs not only improve the handling of your S197 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 stock 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 P-Springs are designed specifically for use on the 2005 to 2010 GT Mustangs Coupes. They will also fit 2011 and newer GT Coupes when used in combination with Ford Racing M-18183-C upper strut mounts and M-18000-A dampers (sold separately). Does not fit V6 or convertible models.

      Im told my 2008 Bullitt already has a lowered spring from the factory. Is this true? It certainly does not look like it. Will this spring drop my bullit even lower if it does?

      • Thank you for your questions about the Ford Performance Lowering P-Springs - Coupe (05-14 GT). The Bullitt does run a different spring rate than the standard GT, and there are some sources stating that it does sit a half inch shorter in the rear. Even if that is the case, these springs drop will still provide a drop against the factory ride height because they are a 1 inch drop in the front and the rear.

      Will these springs be a direct swap for a mustang gt coupe with brembo brake package? Or will i still need shelby strut mounts? My question essentially is.... Can I just swap springs? Thanks

      • If you have a 2005-2010 Mustang GT, it will be a direct swap. If you have a 2011 and newer GT, you will need to get the Ford Performance GT500 Style Strut Mount Upgrade (05-14 All), item # 50273, (http://www.americanmuscle.com/frpp-gt500-strutmount-0512.html) and the dampeners.

      When adding/changing the stock springs on a 2014 GT to these Ford P springs, can the front alignment still be adjusted correctly when using the factory struts with the P springs ??

      • Whenever you change any suspension part on the car, we suggest getting an alignment done. You can get a proper alignment done with factory struts and aftermarket springs. I do suggest getting a set of caster camber plates such as the Maximum Motorsports Caster Camber Plates (11-14 GT, V6, BOSS), item # 47028, (http://www.americanmuscle.com/mm-caster-camber-plates-2011.html). These caster camber plates are double adjustable which will help you get the perfect alignment.

      Hi Just picked up a 2007 GT/CS. Was wondering in stock form if this model is lower than a regular GT. Read somewhere that it is. Would these work well with KYB shocks and struts and should I replace the strut mounts at the same time. Thanks.

      • The GT/CS models and the GT models will be the same ride height. However, these springs will work well with your shocks and it would be a good idea to upgrade the strut mounts as well!

          Ford Performance lowering springs

          These springs were easy yo install. Lowered the car 1inch. I used Ford Performance camber bolt kit instead of caster plates. Took a little extra time to notch struts for adjustment and perform alignment. The result looks great,not too low, just right.

          Perfect set up for 20" rims and 305 tires

          The ride height and feel is perfect for my driving style. I live in Germany so the autobahn and backroads are my daily commute. I have the front/rear springs installed with Koni yellow shocks/struts.

          Great spring for the street

          Paired with Koni STRT dampers and FRPP jounce bumpers (softer bump stops), the road manners are near factory while still providing a mild performance increase. The drop is just enough to get rid of that wheel gap but not low enough to cause ground clearance issues.

          Perfect minimal lowering spring

          I bought these together with the orange Koni's front and back. I needed new shock/strust and decided to change the springs right away. Everything was done in about 5 hours. You definitely need spring compressors for the front springs to get them off. No need when you put the new springs on though. Very happy with the result, just makes it look a little better. Also ride a little stiffer.

          Perfect!!

          Hello peeps!! I am new to the Mustang build up thing. I have a 2008 GT and this is my first mod! I wanted to get a lowered, tougher stance and improved handling. So I ended up getting the Ford Racing lowering P - Springs and the Bilstein HD shocks. Had a local shop do it cause I don't have the tools. Oh man . . . its exactly what I wanted. Car is about 1 inch lower front and rear, so not too much and you wont be scraping every driveway or bump. And the car handles noticeably better!! I ordered an SR panhard bar (I think you will need it, my car's rear axle shifted noticeably) and about to stick that on too. Overall, its perfect for the non-racer, weekend warrior or spirited driver like me. Don't consider anymore, do it.

          Perfect balance

          My car came with Roush springs that dropped it 1/2"= Not enough and the ride was horrible. Then I installed Eibach Sport Line springs = Too much of a drop 1.5" front 2" in the back. The for P springs are perfect and the ride is awesome. When coupled with Eibach sway bars it is a perfect set up.

          Ride is Much More Comfortable Than Expected From Lowering Springs

          I installed these springs along with Koni front struts (with GT500 strut mounts) and Koni rear shocks. The ride is perfect - much better handling than stock but without the expected rough ride. Of course, the ride is slightly harsher than stock, but still okay for a daily driver (mine is). No more truck-sized gaps between the wheels and fender. Super fast shipping as usual - thanks AM!

          Nice Ride!

          The car looks better, handles better and rides bettter, but there is still wheel gap. I thought by dropping it 1 inch and putting on 18 inch wheels it would look awesome, but I still see some gap. I guess it is better than going to low and hotting everywhere though. Just be sure of what you want when deciding on springs. I am very happy with these, despite the gap, they are fine for me.

          Great springs that do what they advertise!

          I bought the Ford Racing P springs with the Ford Racing shocks and struts and couldn't be happier. I wanted a slight drop to increase cornering ability but I didn't want to "slam" my 2013 GT. Having been in auto repair and maintenance for most of my life, I can honestly say that in years past installing springs and struts was a nightmare of a job that I avoided if at all possible. The pre-assembled kit is amazing simple to install and could be done by even rookie do it yourselfers in the driveway with patience and proper tools. I was extremely fortunate and my car didn't even require an alignment afterwards. I will say, perhaps you will want to hold off on ordering a new Panhard bar or Adjustible Camber/caster plates until you find out if you need them. I had already bought a Panhard bar, and it is sitting on a shelf unneeded. It won't hurt to find out you need them and order them afterwards.....better than buying them and finding out they weren't needed and being stuck with the investment. They fully meet the expectations of the 1 inch drop......handling is definitely improved and you can really carve up the corners. The ride stiffness is increased, and there is a little sacrifice of ride quality overall. I would say it's within expectations for lowering and stiffening the suspension. Looks great and works as advertised.

          Just the look I wanted - convertible

          I only used the back springs to get rid of the excessive wheel gap that became more evident after putting wider 20" wheels on. A couple of notes. I used them on a convertible, even though they said they specifically don't fit. They do fit just fine. The convertible is a little heavier so I ended up with about 1 1/8" drop instead of 1", but that was more what I was going for anyway. A note on the install. It is FAR more difficult due to the convertible bracing that extends under the rear end. You cannot lower the rear end low enough to get them in. The "correct" way would be to pull the bracing, but that looked like a BIG job. Instead I used a pry bar to get the old ones out and a cheap set of spring compressors to get the new ones in. Was kind of a pain, but only took 2-3 hours start to finish. A non-convertible should only take 1/2 - 3/4 hour. Looks great though, just look I wanted. I might even put the fronts on sometime, but concerned about dragging the splitter in the front. A little firmer ride, maybe a little bouncier with stock shocks, but not bad. I cut the first ring off the factory bump stops and I am happy with that. JUST DO IT, you will love it.

          I was looking to lower just the rear suspension to level the car out, with out doing damage to the ride quality. I had the rear springs installed only and along with the strut and shock upgrade i think i achieved all my goals.
