    • Progressive Spring Rate
    • Estimated Drop: Front - 15mm; Rear - 35mm

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

    Aggressive Stance. The Ford Racing Springs not only improve the handling of your BOSS Mustang, but they also improve the overall appearance by lowering the ride height approximately 15mm front, 35mm rear for a more aggressive muscle car stance.

    Jounce Bumpers Included. The included Jounce Bumper Stops may look like your stock ones, but the difference is that they are much softer/spongier than stock. So when the jounce bumpers compress, they release slower than stock to provide a less violent chassis reaction when the vehicle bounces off them.

    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 Springs are specifically designed for use on the 2012 to 2013 Boss 302 and Boss 302 Laguna Seca edition Mustangs.

        I have aftermarket rims and tires. The rear are 20x10 Niche Milan’s (40mm offset), purchased from AM, with 295/35/20. I know they will fit, but might they rub the rear fender under suspension compression?

        • With these springs and your whee;/tire setup, you should not experience any rubbing.

        Will I require using an adjustable panhard bar? Some other lowering springs require an adjustable panhard bar due to the axle shifting to one side. Thanks

        • The Ford Performance Lowering Springs will not require an upgraded panhard bar for installation. After installing, we recommend having a professional alignment preformed to assure the rear end is still in in position. This however can be corrected with a panhard bar but is not necessary.

        I have aftermarket wheels and tires 255/35z20 on the front, 295/35z20 on the back. These were purchased from AM and have the offsets you provide

        • The Ford Performance Lowering Springs will work with those tire sizes installed.

        Hello, I have a 2012 Boss 302. I just wanted to know if I need anything else besides the springs to lower the car properly because I am having my local shop install them for me. I understand some springs require additional parts because of the drop. Do these springs require anything else? Thank You.

        • The Ford Performance Lowering Springs will not require additional components for installation on your Boss Mustang.

        Boss owners, do you need caster camber plates to get the alignment right when using these springs? Or just the alignment bolts from eibach, ford racing, etc...

        • This kit will not lower the car enough to need caster/camber plates. You can get it back to the factory specs without needing plates or alignment bolts.

        Good morning, I have a 13 Boss Laguna Seca and i'm considering the Ford Performance lowering springs. I like the look of the front stock stance but not the rear. Can I replace just the rear springs and leave the front stock springs without any issues and would that help the look? Thanks! 1 answer

            Perfect height

            These should have been the stock springs. The ride feels about the same as stock.

            Lowering Spring? Massive drop

            I install these nice spring onto my GT, one thing I was not ready for was the massive drop in ground clearance. This has to be the lowest drop Ford Racing offers. I can no longer hoist the vehicle without ramps and I talking a real hoist like at a dealership. Hope to god I never need a tow truck, not sure if it would make it up the flat bed! Ride quality is a give and take, its not really that bad, mildly impressed. But a washboard road its pretty nuts. I hear from others that appearance wise its much cooler. The springs are noticeably stiffer and the vehicle performs a little differently but nothing in the wrong direction.

            VERY LEVEL but nice springs

            Very nice product but be warned if you are using these on a Boss with stock suspension they will level your your ride front and rear...mine measured 27 3/4 front and rear at the bugged the heck out of me so I installed 285/40/19 rear tires to fix the the rake issue now it looks awesome!

            Lowering Springs

            I ordered these and had them installed. I like the overall look...maybe could have lowered the rear a little more but better than stock version for sure. Have not noticed any difference in ride and I do recommend.

            Boss 302 Lowering Springs

            Great product from Ford Racing. First off, the ride quality remains literally unchanged. As for the height, you do have to be more careful on speed bumps / humps. Appearance-wise, I personally couldn't ask for more. It is perfect. I wouldn't want it any lower as much as I wouldn't want it any higher. Fort Racing really hit the spot. Plus, it's Boss 302 specific and doesn't do harm to your coil overs. It's specifically engineered to work with the stock shocks. 5 stars!

            Straightforward Install

            These FRPP lowering springs are easy to install with the right tools. Jack stands work well, but a lift would be ideal. Note that an adjustable panhard bar and LCA relocation brackets may be required, as well as new LCA's, to get the rear suspension geometry where you want it. My front camber was only 0.1 degree out of spec, so no correction was required (for track use).

            Springs lower perfect amount plus gives the car a stiffer cornering feel but still maintains a comfortable ride when just crusing.

            FRP 2012-2013 Boss 302 Lowering Springs

            I had considered the 2012-2013 Boss specific Steeda springs, the Eibach Pro-lines, and the FRP 5300P springs for my 2013 Boss 302. I decided to wait just a little longer to see if Ford Racing would come through with their version of the Boss lowering springs, because 1) I didn't want to risk doing anything to negatively impact the handling of the car, 2) I found it difficult to determine if the non-Boss specific kits would lower the car by the amount advertised 3) I didn't feel that the Steeda springs would lower the car as much as I desired (Only .2" up front and .8" in back) When FRP finally came out with the Boss springs I cringed a little at the price, but liked what little information was provided in the specs, and decided to pay the extra and give them a try. The install was reasonably straight forward, and it's a good thing, because there were no installation instructions in the box - Just a note directing me to the Ford Racing website for installation instructions. Unfortunately, those didn't appear to exist either. I did however find a youtube video that provided most of the needed install information, and was able to locate the recommended torque specs on another site. All in all, it took 2-3 hours to install both front and rear springs. Although the specifications imply no other parts are necessary, I would recommend you install an adjustable panhard bar to go along with the springs. You shouldn't have any problem with rubbing if you don't, but the rear-end does shift about 1/2" toward the drivers side of the car. After a couple of weeks driving familiar routes, my impression is the car seems to handle slightly better than it did previously (Very flat, very responsive, and still very predictable). I was a little concerned about how the car would handle on choppy pavement in hard turns, but that seems to be fine. Just remember, I'm not a professional racer, so take everything I say for what it is - An amateur opinion! Looks and stance wise, I was very pleased. The front is lowered 1/2" and the back comes down 1 1/2", giving it a nice level stance, but not getting it so low you drag on every speed bump. That's not to say you won't drag on any though! Put a couple of your buddies in the car, and all bets are off. I have the QTP 302 cutouts on mine, and those have scraped the pavement a time or two, so approach those bumps with caution! Overall, I'm very pleased, and would buy the FRP Boss springs again if doing it over.
