Overview

The BMR Suspension SB045R is a rear sway bar designed to control body roll and influence understeer or oversteer behavior. It is manufactured from heavy-duty 25mm bar stock that is cold-formed to resist torsional fatigue and retain its memory. This sway bar features CNC forming for precise tolerances and attaches to the vehicle with 88-durometer polyurethane bushings that reduce deflection compared to stock rubber bushings.
Show original supplier description
The BMR Suspension SB045R rear sway bar is engineered to significantly enhance the handling characteristics of your Ford Mustang (2015-2024). Its primary function is to control body roll and fine-tune the vehicle's understeer or oversteer tendencies, providing a more responsive and stable driving experience. Constructed from robust 25mm heavy-wall DOM tubing, this sway bar is cold-formed to provide superior resistance to torsional fatigue and ensure long-term durability and performance retention, unlike hot-formed bars. The SB045R comes equipped with 88-durometer, greaseable polyurethane bushings, which offer substantially reduced deflection compared to standard rubber bushings. These bushings are designed with internal fluting to effectively retain lubricant. The SB045R is designed for street performance, autocross, and road race applications, offering a 63%-208% increase in sway bar rate, depending on the adjustment setting. Its three-hole adjustability allows you to fine-tune the stiffness to match your driving style and track conditions. The sway bar features a durable red powder coat finish for long-lasting aesthetics. Installation is straightforward, with an estimated time of 1-2 hours.
