Features & Details

  • Aggressive Muscular Stance

  • Fits 2005-2009 Mustangs, excludes GT500
Improves Handling. The most popular progressive rate spring in H&R's line-up, Super Sport Springs will lower your Mustangs center of gravity, to reduce squat during acceleration, body roll in the corners, and excessive nose-dive under hard braking. Sport Springs feature more control than that of the stock springs, but are still comfortable enough for daily driving and occasional track use.

Aggressive Stance. The H&R Super Sport Springs not only improve the handling of your S197 Mustang, but they also improve the overall appearance by lowering the ride height approximately 1.7" in the front and 1.9" in the rear to eliminate that nasty raised 4x4 truck look for a more aggressive muscle car stance.

Application. This set of four H&R Super Sport Springs are designed specifically for use on the 2005 to 2009 Coupe and Convertible Mustangs, including the V6, GT, and Bullitt models. Does not fit the Shelby GT500.

would i need an adjustable panhard bar with these springs?


  • It is not needed but it is recommended because it often messes with alignment below the car.

    Super sport springs

    ive had my hr ss springs on for over a year with just an adjustable pan hard bar, stock struts and stock shocks with no major issue, the ride is in NO WAY unbearable, a lot of people will say that you need his and that or it will feel awful, but the truth is it is still a comfortable ride, to get the full results you will need other things(shocks struts) but you can definitely drive around with stock suspension and springs and be comfortable.

    Waited around a year to put these bad boys on!

    So the story is i bought a bunch of parts from AM over the course of a year and I didn't want to make it Busch league, so I just saved up for everything. So i ordered these then ordered Tokico's blue shocks and struts, camber bolts and then a adjustable panhard bar. Install wasn't as bad as i thought it would be, at first i was going to bring it to the shop but the more and more i thought about it i convinced my old man that we could do it and that it was easy, of course it took a little persuasion lol but in the end i got through to him. Springs were very well built in germany BUT it came with a little american flag sticker!! haha car looks amazing after the drop the back end now looks like a sports car and not a F-350 lol. Overall i am very happy with how everything looks!

    Great springs

    It took me an hour to install these springs. Once I finish I took it for a test drive and first turn i could feel the difference it's more stiff and smooth on the turns. Also you can feel every bump on the road which I don't mind. If your thinking of buying springs I recommend there because it gets rid of the tire to fender gap an gives car an aggressive look.

    Nice handling!

    These springs definetly increased the handling on my stang, not to mention the stance. The only issue that I have is that the ride quality is harsh. I guess that is what is expected when lowering a mustang. I will be changing the shocks and struts later to help improve the ride.

    Product works as promised

    Springs arrived as scheduled in a box with installation instructions and warranty info. Installation was as described without any "by the ways" thrown in. Installation was straight forward and simple to do. My Mustang looks sharp lowered and handles like a race car. Excellent product, easy to install. Just follow the directions.

    Aggressive appearance

    Put these springs on in just a few hours before taking my car to the drag strip. They help drastically with the launch and stopping, and really make my car look aggressive. I am running stock struts/springs, which I recommend upgrading along with the springs. Very easy to instal and the handling and appearance of the car are deffinately worth it.

    awesome look

    The springs lowered my stang 2 inches and look amazing. I installed caster/camber plates as well and would recommend installing them with the springs. Also, a front alignment is needed after install. You can feel every bump in the road but I don't mind. Improved handling and reduced the "squat" during braking and acceleration.

    Lower than the Titanic

    This set of springs is definitely worth the money. It took me about 2.5hrs to install it and all. Used was a bottle jack, jack stands and tools from harbor freight, so you can imagine, it isn't that hard to install them.

    Installed H&R Springs in 6a hours! Made my car look completely different! The ride is a little rougher, but the handling difference is amazing! I can take sharp turns at incredible speed with no problem! You have to know how to drive your car with these springs or you will hit everything! GREAT BUY!

    Excellent Stance

    I installed them myself without the use of any power tools or lift, just a floor jack jackstands and hand tools. The stance is very aggressive now, exactly how i wanted it. Handling did not improve much because i didnt replace the shocks or struts, but what could you expect. Great product I used these springs on my fox too. You need an adjustable panhard bar after lowering to get it exactly correct but i haven't got around to it yet but it is still great.

    H&R Super Sport Springs

    Very easy to install, I installed with new struts and shocks also. I did all the work in my driveway in a couple of hours, there is no need to take it to a shop and have it done. Lowered my mustang about 2 inches, ride quality is great and traction is a lot better with these springs, Gives your car a more aggressive look. I would recommend this product to anyone who wants better ride quality in there mustang.

    Springs are perfect

    Bought these along with struts and shocks. Had them professionally installed. There were no problems after the installation and I loved the stance. Be warned if you don't buy the extra things like sway bar anti rolling kit, lower control arms, pan hard rod and more you will feel wheel hopping. I couldn't stand the wheel hopping so I saved up money to buy the extra things and dont feel any wheel hopping anymore. The ride feels smooth and looks great.

    Outstanding item, well worth it for your GT, V6, greatly improves handling, i noticed it right as i drove off the drive way. installation could not be easier. just make sure you have spring compressors, also instructions are clear and easy to follow. droped my pony down about 1 in front and 1.5 in back, now i have to be carefull over speed bumps. Overall this is a great product and i recomend it to all pony owners who moderatley want an agressive stance on their Mustangs.

    Installed the new springs on my 08 bullitt! Only to about 2 hours to do! Simple and easy. Ride is a little rough but you gotta take the good with the bad. Made my 1/4 mile time go from 13.09 to 12.7. Handles like a dream and looks like a true muscle car!! Highly recommend to every mustang owner
