Overview

Let Steeda take your Non-Performance package S550 Mustang’s handling above and beyond the OE Performance Pack option, competition! Our Steeda suspension packages have been long sought out by competitive racers, weekend warriors, and daily drivers. With this new Steeda S550 Mustang EcoBoost ‘Non-Performance Pack’ Handling Kit for your Mustang EcoBoost you will notice a dramatic difference in the way your car handles and rides. We have spent countless hours making sure all components are fine-tuned to our specifications.

The Steeda Mustang Sport Progressive Springs that come in our Steeda S550 Mustang EcoBoost ‘Non-Performance Pack’ Handling Kit will lower your vehicle 1.125″ in the front and 1″ in the rear. This Steeda progressive spring will be the foundation of your new suspension set up. It will optimize the center of gravity and suspension geometry of your Mustang EcoBoost, resulting in a reduction in nose dive, launch squat, and body roll. These springs will maintain your OE ride quality, but will give you far more responsiveness than any OE spring.

Our Steeda S550 Mustang Camber Plates are great for both street and track use. Our camber plates come into play especially when lowering your vehicle. With the addition of our new adjustable strut mounts on your lowered ‘Stang you will be able to correct excessive negative camber and increase your front steering response. If you lowered your daily driven S550 Mustang, running the correct camber will eliminate uneven tire wear. With the addition of these camber plates you will be able to dial in precise front suspension camber for each front toe adjustments resulting in a more balanced and predictable vehicle on the street or track. You will notice improved overall handling capabilities, elimination of understeer and increase in your Mustang’s turn-in response.

First-hand note

FFP fits Steeda parts every week in Thousand Oaks.

— Why we stock Steeda

OE-style engineering, in-house manufacturing, race-proven on Steeda's own SCCA program.

Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.

We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
