Looking for competition proven handling performance for your Mustang but still be able to drive it on the street? Steeda has the springs for you!

Steeda's Competition/Street springs have been competition proven in NASA American Iron competition. They will greatly reduce nosedive and keep body roll to a minimum for the ultimate in performance.

For maximum handling, we also recommend combining our Steeda X5 ball joint s with our bumpsteer kit.

The springs are also a great match for our Pro-action shocks and struts for 2005-2010 here and 2011-2014 here

Steeda Springs are manufactured under these rigorous manufacturing certifications: QS-9000 & ISO 9001

Note: Not for use on 2011 & newer V6 Mustang, due to lighter front end.

All lowering springs are not created equal. Read our Steeda blog post to learn more:

Competition Springs
I have run the sport springs on my 2010 GT for several years without complaint. I added a supercharger and the extra weight on the nose was more than the springs could bare. I hoped the competition springs would hold the nose a bit higher off the ground but sadly, no. The spring rate is good but they are just too low.

Great Choice over Progessives
'11 V6 I just can't part with. Mostly track car (don't suggest these for road enthusiast) paired with Strange single adjustable shocks/struts, & maybe some other stuff (adj/lighter pan bar/adj front & rear sways). Definitely needed linear for the rear, and I'm too cheap to go with coil overs-GREAT CHOICE!

Excellent be springs
After much research, these were it for my car. I HAD FRPP P-springs but they actually collapsed and the company I bought them from didn't want to back them up. I couldn't get my low profile racing jack under the car! I never have to worry about Steeda backing their products up and these are lifetime warranty. Steeda Competition springs are IT. I have Viking Warrior shocks out back and Koni Yellow up front. Very nice handling combo...and linear rate FTW on a corner carver car.

These are it.
If you're looking for linear rate springs that won't launch you into low orbit on freeway grade separations--THESE ARE THE ONES! Real solid ride but with just enough compliance to prevent the rear axle from stepping out on sharp bumps. You can add 1/2 spacers under the rear coils to maintain that Mustang rake in case you haul moonshine occasionally. Those should disappear on track days when you're winning the championship. The rest of the time load up the trunk with **** and never worry about tailpipes hitting driveway aprons. *Pete*

Amazing handling and stance
This gives your pony the best stance out there - great for daily driving and you can feel the improvement in cornering.

Fantastic ride and handling
I run time attack in my 2012 GT. The performance gain was immediate. Nose dive was reduced, cornering sharper, and the ride is better now than it was before. So why don't I have a perfect 5 star rating on the board? I still drive the car on the street As mentioned in another review, the front end raised up compared to stock. The rear is lowered perfectly. It just looks a tad odd. The average person won't notice, but the hardcore Mustang fan will definitely see something a bit off. If mine was a pure track car, it wouldn't matter at all. Any Mustang with a supercharger on it should sit perfectly.

A good improvement
I take my '12 V6 Manual to the track quite often, and the one thing you notice off hand is the extremely soft suspension on the stock car. Unfortunately, I am not a big fan of progressive springs, and there are very few linear progressive springs in the market, and this is one! I found the difference right away! My turn in was sharper, response was stiffer, and I added a strut tower brace from Ford racing to further tighten the front end. The front end is much more disciplined than before. If you are fan of linear springs, this is a good spring to go with your stock struts.

Great for GT500
These springs were recommended to me by Sam Strano when I first bought my 2009 GT500. Even though they are called competition springs, I was surprised that they improved the ride as much as handling. No more brake dive, and very responsive around the corners. I prefer the way my car ride now, even better than stock. They seem to work well with the stock struts and shocks on the car, so I can only imagine how much better these springs would respond with an adjustable Koni or Tokico setup. One word of caution, unless you have a heavier engine in your standard S197 GT, opt for the Sport Springs. The higher spring rate in the front coil competition spring will actually sit higher than the rear due to the lighter 4.6L aluminum engine. Overall, I give these springs a 5 star rating, as I have been very impressed with the ride and handling.
