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, ( and the dampeners.


Helpful (1)

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, ( These caster camber plates are double adjustable which will help you get the perfect alignment.


Helpful (1)

Please why do you say to also get the Ford 500 strut mounts and to get the 2010 Struts? Will the "P" springs not work with the 2011 Strut mounts? and then I could just buy struts for an actual 2011 Mustang.


Can these springs be direct replacement onto my factory struts ? Thanks


  • Thank you for your question about the Ford Performance Lowering P-Springs - Coupe (05-14 GT). While you can use these spring over your factory shocks and struts, they will fatigue faster and you will want to upgrade to some that are specifically for a lowered application.


Helpful (0)

When I install these springs will I need... Caster camber plates or camber adjustment bolts to correct the alignment.


  • It is a good idea to get caster camber plates whenever you change the suspension of the car. This will help you achieve the best alignment to ensure there is no unnecessary wear.

    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.

    A great product

    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.

    Works as advertised

    These springs are perfect for a daily driver. Clearly improve handling, no noise and nothing too extreme. The drop and improvement in stance is not spectacular though but I clearly prefer not quite enough than too much. I profited to change the rear rubber isolators, bottom and top for $ 65. The car is silent, rides like my Bentley. Install is fairly easy, follow the instructions on this site. For the rear springs, I installed them with markings facing outside and it works fine.

    Great Option for a Better Look and Ride

    I wanted to get rid of the huge gaps between the tires and the wheel wells on my 2010 GT. These springs did the job. Honestly I think I would have been happier with the look of about a 1.5" to 2" drop better than these 1" drop springs but this is a definite improvement. The look and handling is noticeably better and I wouldn't want to go any lower with the stock shocks and struts because they're not valved for it. Being my daily driver I didn't want the ride to be too stiff. These springs stiffen it up a bit but not too much. The bottom line is, for the price I think these springs are a nice option to improve the look and the ride without getting too extreme. I did need to have camber plates installed to get the alignment right though.

    Great ride, great looks, and not too low.

    Wanting to improve the handling and appearance of my car, but not crazy about the "extreme" look and lack of clearance with other spring otions, these were the clear choice. The ride is noticeably firmer than stock, but not so firm that long drives leave you tired or sore. The car stays much flatter on acceleration and breaking, as well as cornering. Much improved from stock, and I still have enough clearance to make it into steep driveways or down country two-track paths.

    I researched and read every review I could find on spring/strut/shock upgrades for my 2007 GT. Finally decided I could not go wrong with the FRPP "P" springs and Bilstein HD combo. Installed Ford's strut mounts, as well. I now have a little less than 500 miles on this setup, and I could not be happier. No other parts required to make this work. Looks good, rides great. Service from American Muscle was flawless.

    Better handling

    While the ride isn't as smooth, that was the problem to begin with. Too soft before did not inspire confidence at 'speed'. It feels more secure now, but there's still a stretch of road I want to take my Stang on for a final test.

    well worth the investment

    Debated between the K and P springs due to wanting to keep my investment to a minimum. Using the OEM shocks and strut mounts on my 2012 to save money, I could not be happier! Ride is exactly the same as OEM, which really is not a compliment. Ride is still soft and supple which may be OK for some, but not for me. Will definitely be replacing struts and shocks better suited for these springs. Quality is top notch, and are great for getting rid of that 4 finger gap that comes free with every stock GT. No regrets! Do them if looking for a subtle drop. Could use 1/2 inch more in rear for a truly leveled look.

    Drop as advertised

    Installed rear springs only. With a full gas tank and 36 lbs. in the tires, the rear height drop from 29 1/8" to 28 1/4" as measured from the ground thru the center of the wheel to the bottom lip of the rear fender. The car looks perfectly level now. After 100 miles, the springs settled about 1/8" and I have noticed no change in ride quality. Highly recommended.

    Just the rears = Just the ticket!

    Installed just the rears to even out the front and back gaps. Results were perfect. In less than 40 minutes, the ride looks nice and even (see customer image- its the Sterling Gray with Boss style silver stripes showing before and after). I just wish they sold the rears only- but for the price it can't be beat! Even seems to have reduced the wheel hop a bit for some reason I can't determine!

    Great springs from FRPP and AM!!!

    Fast shipping (2-3 days!), packaging left a little to be desired (springs were only in a box with thin cardboard dividers), have to slide the spring's isolator tubing back down to the bottom, but work like a charm. Can install without the need of a spring compressor, easy on Tokico D-specs (must have compressor to remove the old ones, though)! As advertised, dropped approximately 1.0" when I didn't want to slam the car; great deal for those that don't want to scrape the ground or have to do bumpsteer upgrades. Don't forget to measure your strut center stud-to-tower distance for reinstall, then alignment! Rear was a piece of cake!

    These are the springs that should come on the mustangs to start with. The ride is a little stiffer but to me feels like a performance car should. I tried installing the front springs without a spring compressor. Take my word for it, buy or rent a spring compressor. I'll just conclude by saying there are a lot of tiny ball bearings in the strut area.

    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.
