Springs are the foundation of good handling. So start with the best. Our experience and expertise in high performance street and racing suspension systems is second to none. Put that experience to work for you. Steeda springs are all custom made to our specifications. Specifications that have been refined and improved through years of testing.

Steeda's performance lowering springs improve the overall handling of the by lowering the center of gravity and reducing body roll and pitching during braking. The reduced longitudinal pitch of the vehicle during heavy braking improves the overall braking efficiency. The higher rate of the front springs reduces the amount of load transferred to the front tires. This causes the load on all four tires to be more evenly distributed providing additional traction to the rear tires. The additional gain in rear traction can also improve brake performance and result in reduced braking distances.

The increase in spring rate also reduces body roll, which improves handling and steering response. Reduced body roll also confines the suspension geometry to stay within parameters that enhance the tire contact patch relative to the road, The result is improved vehicle cornering and handling. Higher cornering limits can be achieved as the built in understeer characteristics of the vehicle are reduced and provide for a more neutral handling platform.

All these benefits along with the excellent ride quality Steeda Sport springs are famous for. Steeda Sport Springs give you the best of both worlds. Performance and ride quality.

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

Product Reviews

I've had these on my 86 GT for a couple years now. These springs are the best of both worlds in my opinion. They have great manners on the street and handle dips, bumps, and the horrible road conditions Michigan has to offer just as good as an OEM spring - but provide a great increase in responsiveness, reduced body roll, improved grip, and lowered stance.
The quality of the construction of the springs is also top notch. The factory finish hasn't faded in the least bit either. I recommend these springs to everyone.

Have had these installed for a year now along with some Tokico HP shocks/struts, and absolutely love how they make my '02 GT handle. While I do wish they lowered my car a bit more (1.5" with top isolators removed), that would not be very practical for a year round daily driver. Highly recommend to anyone looking for a high quality spring.

These springs gave my Mustang the look and ride that it should have had from the factory. The ride height was lowered enough for good looks but not so much that it bottoms out in parking lots. The ride quality has also improved compared to the factory setup. The handling was improved over factory on the street and in more aggressive driving conditions. Letâ

The quality, finish and overall perfomance and appreance of the springs is excellent. Installation is not to hard just remove your sway bar which I was upgrading to a new Steeda sway bar, and the tie rods, and then unbolt the two long bolts holding the A-Arms to the frame ( hint instead of removing the outside bolt when sliding out the inside bolt just slightly apply pressure and once the lip or the bolt is passed the bolt head yu are sliding under it will just slide right out, instead of busting your behind trying to pry/breaker bar the bolt attached to the frame/sill plate, saves so much time!) Then putting the springs in is a breeze no commprssor needed ( but you also can and/or use one for safety! when re-installing) they will slide in, I purchased the X2 balljoints and the polyurethane isolaters/pads and they wrk great and are better then the rubber stock ones; and you can jack the A-Arm back up and slide the before mentioned bolts back in that conect the A-Arms to the cahssis; then tighten everything back up when the suspension is loaded. It will lower you car about 1"- 1 1/4" or if not using the plates with the X2 ball joints 1 1/2"- 1 3/4". Installing the stock springs gives your car an agressive look a nice firmer and better handling ride, but will not sacrafice that much to notice on road harshness or ride, it is still smooth enough for daily driving. I reccomend also buying the offset A-Arm bushings and the offset sterring rack bushings as well. Both will benifit when lowering your car, the extra caster will help with if any bumpsterr which their is almost non and helps in cornering, and the offset sterring rack bushings which you till have to remove or slide out when installing the springs so just buy the offset steering rack bushings to help prevent bumpsteer, and they do help with that as well as firm up the sterring response. All in all a really good designed spring and with the extra parts mentioned a perfect lowring kit!

I got these and some Tokico HP shocks and struts as the first major modification on my '90 5.0L hatch, and I'm glad I did. The stance is perfect, with just a tiny amount of rake and its just low enough in the front to get rid of that monster truck wheel gap but it still doesn't rub (with stock rims anyways). The handling is also noticeably better, and the ride is better than stock, but I did have blown up shocks so I don't have a good basis for comparison. Also one important thing to note is any lower and the car would start to drag on rough roads, I am pretty close with my 2.5" exhaust and full length subframe connectors, I think any lower would start to have issues on rougher roads.

I installed these springs on my 1997 Mustang GT. The stance was beautiful, but did not compare to the ride. The linear rate allowed my car to ride comfortably when I was running about, but firmed up when I was at the track. The performance continued to improve with speed and the springs would drop an additional 1/4" over 220km/h. I would definitely recommend these springs on any SN95 model.
