We've made quite the collection of suspension packages that are heavily focused on handling with the S550 Chassis. These packages were developed, tested, and hand-crafted by our very own Steve Gelles, along side Scott Boda and Chris Cervenka from Steeda, with the pure intentions of making an easy choice for those looking to boost their cars' handling capability, without ruining the nice, quiet ride quality by producing any N.V.H, or Noise, Vibration, and Harmonics.
Starting development on Steve's personal Whipple-Charged 2018 Ford Mustang Saleen S302, the boys at Steeda started off slowly adding parts to build. As each "Level" of parts was added to the build, the car was taken out, thrashed on a bit, and data on differences was noted and sent back to Scott & Chris. Now, we have taken the entire process and compressed it down into Levels, starting with some of the most popular basics that just about every Mustang owner starts with and eventually leading to an entire suspension overhaul.
This is going to be the perfect starting ground for just about any S550 Build, as it covers for both increasing the looks AND handling, but correcting the geometry.
- Your choice of Steeda's Lowering Springs, depending on your application and/or build goal.
- Your choice of a Front Camber Adjustment, again, depending on goals as with Camber Plates, you will gain slightly more adjustment capabiltity than with the Camber Bolts.
- Steeda's IRS Bushing Support System
(Choice based on application)
Bumping up the stiffness of the chassis of the car, focusing now on the rear section.
- Steeda's Rear IRS Subframe Support Brace
With this brace, you can now limit the movement of the subframe by filling in the voids of the OE bushings.
Anytime a piece is moving, twisting, or vibrating when it should be stationary is a problem effecting the stability and handling of any car.
Now we're finally getting into some of the major changes in the chassis where you truly start to feel the car become like it's on rails...
- Steeda's Adjustable Front and Rear Swaybar Kit
- Steeda's Billet Aluminum Vertical Links
(choice based on application)
- Steeda's K Member Brace
(choice based on application)
Taking away body roll, as well as stiffening up that K-Member truly helps the S550 Chassis feel together.
With the addition of an often over-looked aspect of many street-driven builds, a shock and strut upgrade is one of the most crucial pieces to having a good driving car.
- Steeda's Pro-Action / Pro-Active Shocks and Struts!
(Choice based on application and build goals.)
This level is mainly for the Non-Magne-Ride cars, since you Magne-Ride guys already have some fairly high tech suspension. This is currently the level that Steve keeps his car at, as he finds it just enough for his style of driving through the mountains of Tennessee and North Carolina, as well as the occasional on-ramp excitement!
This is the total package and as far as you can really go on Handling mods for the S550 without getting into NVH.
- Steeda's Rear Adjustable Rear Camber Arms OR their Camber Adjustment Kit
(choice based on build goals, as their Camber Arms will have much more adjustability than the Camber Adjustment Kit)
- Steeda's Mustang Adjustable Rear Toe Links
With these two components added on, you can now fine tune the rear camber and toe of your S550, while upgrading the stiffness from your OEM components.
An IRS subframe support brace helps limit movement in the rear subframe, which can improve stability, predictability, and handling response. It is especially useful for drivers looking to make the S550 feel more planted.
Upgraded sway bars help reduce body roll in corners, keeping the car flatter and more controlled. This can improve turn-in feel, confidence, and overall road-holding performance.
Vertical links help control rear suspension movement and improve stability under acceleration, braking, and cornering. On the S550 Mustang, upgraded vertical links can make the rear suspension feel more precise.
A K-member brace helps stiffen the front chassis structure for improved steering feel and overall rigidity. This can make the Mustang feel tighter and more composed during aggressive driving.
Level 4 adds upgraded shocks and struts, such as Steeda Pro-Action or Pro-Active dampers, depending on the application. This is a major step for improving ride control and suspension behavior.
Yes, these Steeda suspension packages are built with street use in mind. The goal is to improve handling performance while maintaining a comfortable and refined ride for regular driving.
Lowering springs can improve the car’s stance, lower its center of gravity, and sharpen handling response. They are also one of the most popular first upgrades for S550 Mustang owners.
Lowering a Mustang changes suspension geometry, which can affect alignment. Camber plates or camber bolts help restore proper adjustment and improve tire wear and handling balance.
