Bumpsteer Kit - Mustang 15-20

The STEEDA AUTOSPORTS Bumpsteer Kit for Mustang 15-20 is a precision suspension geometry correction system designed to eliminate bump steer—the unwanted steering input that occurs when a vehicle's suspension compresses and extends over rough pavement or track surfaces. This adjustable kit restores predictable steering response during aggressive cornering, trail braking, and weight transfer events by fine-tuning the relationship between suspension travel and steering linkage angle.

The kit includes adjusting sleeves, hardware, rod ends, and spacers—the complete set of components needed to dial in proper steering axis inclination (SAI) and Ackermann geometry for your specific suspension setup. Bump steer is particularly noticeable in lowered vehicles, lifted trucks, or cars running modified suspension components where original OEM geometry no longer applies. By allowing independent adjustment of the tie-rod height relative to the control arm pivot points, this system lets drivers compensate for suspension changes and achieve neutral steering feel across the full range of suspension travel. The 2.55 lb kit is compact enough to store easily while containing all fasteners and rod-end components required for professional installation.

This bumpsteer correction kit is essential for 2015–2020 Mustang owners running lowering springs, coilovers, or custom suspension geometry. Track drivers, autocross competitors, and street enthusiasts experiencing wandering or twitchy steering inputs during corner entry will benefit from the adjustability this system provides. Proper bump steer correction improves front-end stability during weight transfer, reduces mid-corner steering corrections, and enhances overall suspension tuning precision when combined with other geometry modifications like camber plates or control arm adjustments.

STEEDA AUTOSPORTS is recognized in the Ford performance community for suspension and chassis components engineered to restore or improve handling characteristics on modified vehicles. Bumpsteer kits address a real geometric problem that factory suspensions do not anticipate when altered, making this a foundational upgrade for any serious Mustang platform suspension project.
