Give your 2015-2017 Mustang the proven performance of Steeda manufactured suspension parts. This Steeda Stage 1 Handling Package - Sport Progressive for your 2015-2017 Mustang EcoBoost is designed to improve cornering grip, handling balance, reduce brake dive, and reduce body roll while maintaining exceptional ride quality.

This Steeda Stage 1 Handling Package - Sport Progressive for your 2015-2017 Mustang EcoBoost will also lower the vehicle about 1.125" in the front and 1" in the rear, for a great appearance and improved weight distribution.

Our Steeda Stage 1 Handling Package - Sport Progressive come paired with our Steeda Mustang Sport Springs - Progressive. These springs are a great daily driving spring much like our other line of Steeda Springs, and are engineered to perform exceptionally on the track. The progressive rate of the springs will increase spring rate as your Mustang's body roll increases, giving you improved corner handling at high speeds.

Our sway bars have machined steel billet sway bar ends, whereas others on the market have coined ends. What does this mean? Our sway bar ends are machined out of billet steel round stock, in-house, on our multi-axis CNC lathes and go through hundreds of computer simulations to ensure the ultimate in strength and performance - this provides greater resistance to bending stresses, and has three major advantages:

• These parts are less prone to cracking/fatigue failure on the ends themselves.
• It also reduces unwanted deflection in the sway bar end. Excess deflection creates unwanted geometry changes, which physically changes your sway bar stiffness to a non-ideal rate.
• With less unwanted deflection, our bars will 'wear out' slower - any spring will eventually become softer over time as it is cycled through its life, our bars will maintain their designed rate for longer with less unwanted deflection.

Our bar rates are developed and optimized through advanced vehicle dynamic simulation and through extensive real-world testing. 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.
