Product Overview

If your S550 Mustang spends more time turning laps than grabbing groceries, Steeda's S550 Mustang Dual Rate HPDE Suspension Package is your ticket to victory lane! A race proven kit which has laid down impressive times with Steeda's own 2016 and 2017 Mustangs, the HPDE Package comes with Front and Rear Adjustable Sway Bars, Adjustable Pro-Action Shocks and Struts, and Competition Dual Rate Springs.

Our Steeda Mustang Front and Rear Sway Bars for your 2015+ Mustang GT, EcoBoost, or V6 provide an increase in front and rear roll stiffness for a balanced handling package. The press-fit welded billet ends are far stronger than stamping the end of the bar. Billet machining construction of the Steeda Mustang Front and Rear Sway Bar ends makes for far greater strength for a bulletproof sway bar. We engineered these bars to control the vehicles' roll stiffness properly while still allowing you to run softer springs. This optimizes your overall grip and balance of the vehicle while still allowing you to maintain exceptional ride quality.

Our Pro-Action Adjustable dampers feature street and track-proven technology which have been methodically tested and tuned to achieve optimum compression valving, giving you that quick sports car reaction on the road with easily adjustable rebound damping at the twist of a knob. From soft and com fortable to stiff and aggressive, these Pro-Action shocks have more adjustability than you will ever need!

The Dual Rate Competition Springs, which have the highest rates on the market, greatly reduce nosedive and keep body roll to a minimum for the ultimate in per formance handling. By lowering your S550 Mustang .750" all around, these springs provide an optimized center of gravity and an aggressive stance.

Competition proven in both NASA and SCCA events, this suspension package is going to make your 2015+ S550 Mustang an absolute winner on the track! Installed on our 2024 Mustang GT HPDE build along with our 'Stop The Hop' Handling Ultimate Kit, we achieved over a 2 second improvement in our lap times!

Note:Front Sway bar will not fit vehicles equipped with MagneRide Suspension. The factory shock mount will need to be drilled out to 12mm or theSteeda Billet Shock Mountscan be used.
