Overview

Give your 2015+ Mustang the proven performance of Steeda manufactured suspension parts. This Steeda Stage 1 Handling Package for your 2015 Mustang GT or V6 is designed to improve cornering grip, handling balance, reduce brake dive, and reduce body roll.

This Steeda Stage 1 Handling Package for your 2015+ Mustang GT or V6 will also lower the vehicle about 1 inch all around for a great appearance and improved weight distribution.

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.

Key Benefits

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.

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.
